The article tells about one of the reasons for the high fuel consumption, as well as the extremely unstable operation of the engine on the Chinese car Geely MK (aka MK-cross, because they have the same engines). The method of diagnosing this malfunction and methods for checking actuators and sensors are described. Read the article...
Geely MK KROSS
Actually, all of the following is fully true for such Chinese as: solano, breeze, emgrand and x60. Although the motors on them are different, but this does not change the essence of the matter.
Brief description of the fault
Very, according to measurements, when driving on the highway with a more or less constant speed, the car eats a hundred 12 liters. For a 1.5 engine, this is an excessively high consumption.
The car stalls at idle. That is, when the accelerator pedal is released, it can work normally for some time and stall at any time, regardless of external circumstances.
How to look for the reason?
Let's start from simple to complex. P checking the air filter-everything is normal here, there are no traces of oil, dirt too. Knot throttle valve- just remove the corrugation coming from the air filter. The throttle valve should not bite when moving and there should not be too much dirt or greasy deposits in the throttle itself.
If there are oil stains in the throttle, then this is an occasion to thoroughly check the motor. We twist and check the spark plugs. here on all four candles black soot was found. The presence of such carbon deposits on the insulators of the candles tells us that a very rich mixture enters the engine (a lot of gasoline or little air).
But we have already checked the air intake channel, everything is clean here. And suspicion falls on the fuel system. We connect the device for fuel pressure gauge and take the necessary measurements. Pressure 2.6 bar, this is the norm for Geely MK.
Here I will explain a little about fuel pressure. The fact is that the nozzles open with pulses for a certain time, for example, 2 microseconds. At a pressure of 3 bar, one amount of fuel is injected during this time, and at an increased pressure (for example, 6 bar), much more fuel will pass through the nozzle in the same time. Here is a rich mixture for you.
So do not forget about the fuel pressure in the rail, it also depends on how voracious your friend's car is. If the pressure is too high, then the cause may be in the fuel pressure regulator or in the fuel pump itself.
But in our case, everything was fine with the pressure. The option that the injectors “pour” (ie, they let fuel through when closed) was discarded into the far corner. Still, such a disaster for all 4 nozzles at once is a rarity.
This is where the "manual checks" end. We checked the air intake duct, everything is normal there. We checked the fuel supply, it would not be superfluous to remove the nozzles and check them on the stand. But…
Connecting a diagnostic scanner
Well, then everything is trite and simple (for me), among other parameters, the engine control unit also outputs air pressure in the intake manifold. And here a very overestimated value immediately catches the eye: 66-70 kPa, and the normal value of air pressure in the Geely Mk engine at idle is 29-39 kPa.
Conclusion: the air pressure sensor in the intake manifold is faulty. It gives incorrect readings, that is, it shows the control unit that a very large amount of air is entering the motor. The block reacts to this by increasing the injection time, so a large amount of fuel also begins to enter the engine.
A visual guide to the repair of Geely MK will allow each visitor to the site to independently troubleshoot the car. Recommendations from experienced owners will exclude the possibility of making mistakes, and photo and video materials will allow you to quickly understand the algorithm of actions necessary to repair or replace a part.
Despite this, it is impossible to cover all questions on the topic of repair and operation of Geely MK. In order to get help on a specific problem, it is enough to visit the corresponding page of the portal and wait a bit until other visitors give a comprehensive answer along with valuable recommendations.
If at this point in time there are no signs of breakdown, do not miss the time to study the most common repair procedures. From time to time, car owners will need to know how it is carried out, the gearbox and other details. Often, an instruction will come in handy explaining how the clutch is performed or replaced. In addition, information regarding the most popular procedures will be useful. For those who want to master the repair of Geely MK with their own hands, replacing the stabilizer is useful, and.
Geely MK - from start to finish
The Geely MK model was developed in 2006. The front-wheel drive car received 2 body options: "sedan" and "hatchback". Despite the use of 1.3 and 1.8 liter engines in China, a model with a 1.5 liter volume entered the foreign market. As for other characteristics of the motor, its power is 94 hp. It consumes fuel economically and does not create problems even in conditions of active operation. Since the beginning of 2010, Geely Automobile has entered into an agreement with the manufacturer Derways to assemble Geely MK cars in the Russian Federation in its own plant.
In the same year, a new modification of Geely MK called Cross appeared. The city crossover received a compact body, sports body kits, additional moldings, new radiator and many other exterior elements. The interior decoration of Geely MK has also changed. The red and black colors in the upholstery emphasized the car's sporty orientation and became an excellent addition to the overall design.
Geely MK Сross is equipped with a digital display on the instrument panel. Its engine remained unchanged, but at the same time could boast of low fuel consumption- only 6.3 liters per 100 km.
In 2011, the Chinese version of the Geely MK Сross model was rebranded. In order to improve the image, the company decided to change its name to Englon Jinying Cross. The name change also affected the model without modifications. After the marketing ploy, she became known as Englon MK.
Since 2015 Geely MK was completely replaced by Geely GC6- a car that has undergone a complete restyling to radically differ from its predecessor.

Geely MK is a Chinese representative of class C, which is a development of Geely Automobile companies. In recent years, the Chinese auto industry has made a real breakthrough in the automotive industry. One of the main components of the popularity of this model is the design - the appearance of the car is not typical for an eastern manufacturer and is more reminiscent of an "American". It is not worth comparing this car with Americans, Japanese or Koreans, since they are higher in build quality and components, but this model has one parameter in which it surpasses all its competitors, and this is its price, and this parameter has always been one of the main when choosing a car. And, here's how the low cost of the car affected its reliability, and what you should pay attention to when choosing Geely MK with mileage in the secondary market, now let's try to find out.
A bit of history:
In the domestic Chinese market, the premiere of Geely MK took place in 2006, but in the CIS this model appeared only in the middle of 2008. The first generation Toyota Yaris was taken as the basis for the development of the car, and motors from Toyota are also used on cars. Geely previously bought these engines from Tianjin Industrial (FAW), which is licensed by Toyota. In January 2010, at the plant of the automobile company "Derways" in the city of Cherkessk (Russia), the production of cars for the CIS markets was launched. Prior to this, Geely MK were delivered to car dealerships straight from China. In 2011, Geely rebranded, as a result, the car was named Englon MK, and MK Cross was renamed Englon Jinying cross. The rebranding was carried out in connection with a new marketing strategy aimed at updating and raising the brand's image. In 2015, Geely MK was replaced by GC6, which is a deep restyling.
Weaknesses and shortcomings of Geely MK with mileage
The metal, like the paintwork, is very thin, because of this, chips and dents appear even from a small pebble that has flown out from under the wheels of oncoming vehicles. The body is weakly resistant to aggressive environmental influences, which is why rust appears on the car body after a couple of years of operation. Corrosion appears most quickly on the bottom of the car (additional treatment with anti-corrosion agents is required) and in places where the paint is chipped. Also, watch for rust can be found on: the front doors (under the seal), the hood and the gas tank cap (near the lock). The protective glass of foglights often cracks when used in cold and wet weather.
Engines
Geely MK was equipped only with gasoline power units - 1.5 (94 hp), 1.6 (107 hp). The most common engine in the CIS is a 1.5 liter unit, which was assembled under license from Toyota (a copy of the 5A-FE engine from). If we talk about its reliability, then, in general, the motor is not bad, but a couple of weaknesses in it, nevertheless, have been identified. The first thing you need to pay attention to is the timing belt. According to the regulations, it does not require replacement up to 60,000 km, but, as operating experience has shown, cracks appear on it after 40,000 km, and a couple of teeth may also be missing, I think it’s not worth explaining what consequences this can lead to. For those who like to carry out repairs in their garage, it is worth considering the fact that in order to replace the timing belt, you will have to remove the right engine mount.
It is not uncommon for owners to encounter trouble when an unheated engine starts to triple, fortunately, to solve the problem, you can do without a trip to the service - you need to change spark plugs, high-voltage wires or ignition coils. If these manipulations do not give a positive result, you will have to adjust the valves. To perform this procedure, you should contact an experienced specialist, since improper adjustment of the valves can lead to their “clamping” after 40-60 thousand kilometers and with subsequent burnout. Remove high-voltage wires very carefully, as there is a high risk of breaking them.
On vehicles with a mileage of over 50,000 km, coolant leaks appear through the throttle heating gasket. If the defect is not eliminated in a timely manner, this can lead to premature failure of the idle speed controller. The main signal of a malfunction of the regulator will be: difficult start, the engine stalls immediately after setting and starts only when you press the gas pedal. A new regulator will cost 20 USD, but you can save a little by installing an analogue from the Chevrolet Niva (8-10 USD).
In the warm season, it is necessary to carefully monitor the temperature of the engine, most often the engine overheats when driving for a long time at a speed of 80-100 km per hour with the air conditioner on. The main reason is not turning on the cooling fan, poor contact at the wiring terminals and belated opening of the thermostat. The ability to control the temperature of the engine and prevent its overheating is complicated by the fact that the temperature sensor can give incorrect data. If it is not possible to warm up the engine to operating temperature for a long time, most likely the problem is related to the souring of the thermostat in the open position.
On most specimens, on a run of 80-120 thousand km, it is necessary to change the cylinder head gasket, the reason is the cylinder head gasket burns out. At the same run, the pump needs to be replaced. The cooling radiator is subject to corrosion. A signal that there is a problem will be red spots that appear in the expansion tank. With the advent of cold weather, a cooling radiator may begin to flow at the junctions of plastic and metal. On a run of 80-100 thousand km, it becomes necessary to replace the front crankshaft oil seal (oil smudges appear). Once every 60-80 thousand km, an oil pressure sensor needs to be replaced. A slightly smaller resource (40-60 thousand km) have engine and gearbox mounts. Many owners blame for high fuel consumption, in the combined cycle 8-10 thousand km, and this is much more than the manufacturer promised.
Transmission
Geely MK was equipped with only a five-speed manual transmission. Transmission diagnostics should be treated with the utmost care. The main ailment that owners have to deal with is the fragility of the bearings of the primary and secondary shafts. Most often, owners of cars with a mileage of 50-70 thousand km turn to the service with complaints about extraneous noise in the box. You will have to spend 100-150 USD to eliminate the malfunction. Semi-axle oil seals are not famous for their durability either, as a rule, oil leaks appear after 30-40 thousand kilometers. On a run of 60-70 thousand km, the clutch master cylinder needs to be replaced. To save a little, the cylinder can be repaired using a special repair kit. When using low-quality oil, with the onset of cold weather, there are difficulties with shifting gears. The clutch, with careful operation, can last 80-100 thousand km (a set of a new clutch with a release bearing will cost 40-60 USD).
Features and disadvantages of running Geely MK
Geely MK uses a standard suspension for this class of car: MacPherson strut in front, beam in the back. As for the reliability of most elements of the running gear, the situation here is not so optimistic. Most often, it is necessary to replace the stabilizer struts, for inaccurate drivers they go less than 10,000 km, with careful operation they can last 15-20 thousand km, bushings up to 40,000 km. Shock absorbers serve 50-60 thousand km, but there are often cases when they had to be changed even after 30,000 km, since their price is not too high up to 50 USD. PC. Front wheel bearings, levers and ball bearings can please with a mileage of 70-80 thousand km. CV joints are able to last up to 100,000 km. In order to be less likely to deal with chassis repairs, many owners, when selecting spare parts, prefer interchangeable parts from different Toyota models.
There are backlashes in the steering rack even on practically new cars, the reason lies in the poor-quality assembly of the assembly, fortunately, it is enough to tighten it to eliminate the defect. The rail resource differs little from a similar part of most Japanese and Korean manufacturers (100-150 thousand km). Buying a new rail will cost 150-250 USD. Steering tips require replacement every 50-60 thousand km, traction every 70-80 thousand km. There are problems with the brake system, the main one is the corrosion of the brake piston, which leads to brake jamming. Also, the rear cylinders require special attention, there have been cases when smudges of brake fluid appeared on them.
Salon
The interior of Geely MK cannot boast of the quality of assembly and materials, and thanks to the use of hard plastic, crickets feel at home here. If during the movement a rattling is heard from the steering wheel, it is necessary to check the degree of tightening of the bolts holding the airbag (they are unscrewed over time). During intensive use, the front seats can be wiped out in a year, taking the heating elements with them. If you neglect the replacement, everything can end in a fire. Due to poor-quality sizing of the windshield and constantly flying off rubber plugs on the bottom, water appears under the driver's and front passenger's rug over time. Also, after heavy rain, a puddle may appear in the trunk, the reason is poor-quality seals for the rear lights and rear shock absorber supports.
As for the electrics, then, most often, unpleasant surprises are presented by the heating of the rear window, mirrors and the climate system. Many owners complain that the air conditioner does not cope with its duties even in cool weather. On a run of 80-100 thousand km, freon leaks appear, on the same run the air conditioning compressor may jam. At the most inopportune moment, the stove fan may stop turning on, the reason is the failure of the speed controller relay. After 100,000 km, problems begin with the voltage regulator (repair or replacement of the generator is required), as a result of which the battery stops charging. Due to the failure of the microcircuit of the driver board of the electric motors, the backlight of the instrument panel stops working.
Outcome:
Despite significant progress in the automotive industry, the Chinese auto industry is still not up to the level of Korean and Japanese manufacturers and Geely MK is no exception. It is impossible to call this car bad, since the small resource of some parts is justified by the low cost of the car, the cheapness of repairs and maintenance.
If you are the owner of this car model, please describe the problems that you had to face during the operation of the car. Perhaps it is your review that will help readers of our site when choosing a car.
Sincerely, editorial Autoavenue
The Geely MK engine has a timing belt drive. From experience, the condition of the belt does not interfere with checking at a run of 40-50 thousand km. Some do not show the slightest signs of wear for 60 thousand km, while others may already lack a couple of teeth, and the belt is covered with cracks. When replacing the timing belt, the right engine mount must be removed.
With a cold start, the Geely MK motor often starts to “troit”. It is possible to solve the problem after replacing the candles, high-voltage wires, coils (1 thousand rubles) or adjusting the valves. When removing high-voltage wires, owners often tear them off. Neglecting to adjust the valves is fraught with their "clamping" with a run of more than 40-60 thousand km and subsequent burnout.
The gasket on the throttle heater begins to leak antifreeze over time. Drying, the coolant contaminates the channel of the idle speed regulator and the regulator itself. The result is a difficult start, the engine stalls immediately after setting and starts only with the gas pedal depressed. Whatever leak occurs, after cleaning the channel, it is better to put the throttle gasket on a heat-resistant sealant. A native new idle speed controller costs about 1 thousand rubles, an analogue for a Chevrolet Niva for 500 rubles is suitable as a substitute.
The Geely MK motor is prone to overheating in the warm season when driving for a long time at a speed of more than 100 km / h with the air conditioner on. The problem appears with a run of more than 40-50 thousand km. One of the reasons is the failure of the cooling fan due to poor contact at one of the three attachment points of the ground wire. Also, the cause of overheating can be the late opening of the thermostat and the peculiarity of the operation of the engine ECU, which gives the command to turn on the fan even at critical coolant temperatures. The coolant temperature sensor itself may give incorrect values due to acidification of the contact terminals. "Underheating" or a long warm-up of the motor indicates the souring of the thermostat in the open position, which is also not uncommon. A new thermostat costs about 200 rubles.
Some owners are faced with the need to replace a burnt cylinder head gasket. The engine liquid cooling pump may fail with a mileage of more than 50-100 thousand km. Bewilderment causes the appearance of rusty spots in the expansion tank. In frosts, cooling radiators often flow at the junction of plastic with metal.
The sealing ring of the exhaust system at the junction of the exhaust manifold with the pipe often has to be changed due to burnout. With a run of more than 80-120 thousand km, the front crankshaft oil seal begins to leak. The oil pressure sensor may fail with a mileage of more than 50-60 thousand km. The rear engine mount runs for more than 40-60 thousand km, after which it starts knocking. A new support will cost 1.5-2 thousand rubles.
The 5-speed "mechanics" on the new Geely MK suffer from poor gear shifting for the first few thousand kilometers. After the elements of the box “roll in” and there are no problems with the ease of shifting gears. A considerable contribution to the poor speed selectivity is made by the “cheap” oil poured into the box during assembly. Such a "transmission" thickens very much in the cold. After changing the working fluid, the operation of the box improves.
With a run of more than 50-70 thousand km, the box starts to make noise. The reason is the wear of the bearings of the primary and secondary shafts. It is noteworthy that the box bearings are listed in the warranty book as a separate item, and the warranty for them is only 30 thousand km. About 3 thousand rubles will have to be paid for the work on removing and installing the box, about 4 thousand more rubles for the bulkhead, a set of new bearings will cost 1-2 thousand rubles.
The clutch takes care of more than 90-120 thousand km. A new set with a basket and release bearing will cost 3-5 thousand rubles. With a run of more than 100 thousand km, the box often starts to make noise when the gas is released in third gear.
Drive oil seals can leak after 30-40 thousand km. The cost of the drive gland is about 500 rubles. After 50-60 thousand km, it may be necessary to replace the clutch master cylinder. A leaky cylinder can be restored using a repair kit for 600 rubles.
The anthers of the outer CV joint will most likely have to be replaced with a run of more than 100-120 thousand km. Original anthers cannot be found separately, as they are only sold assembled with a drive. But picking up an analogue in a spare parts store from other car brands is not difficult.
The Geely MK suspension is not very durable. The front stabilizer struts are the first to be surrendered with a run of more than 20-30 thousand km. The stabilizer bushings run a little longer - about 40-60 thousand km. Shock absorbers can leak or knock with a run of more than 30-60 thousand km. The cost of a new one is in the range of 1.5-2.5 thousand rubles. Front wheel bearings serve more than 60-80 thousand km. The same amount of ball and suspension arms go. A new ball joint costs about 800 rubles.
Due to the “curve” of the assembly, the steering rack has a transverse play, which is removed after tightening. Often the rail begins to leak after 50-100 thousand km. The cost of a new rail is about 15-20 thousand rubles. Tie rods and tips go more than 50-80 thousand km.
Due to corrosion of the piston coating of the brake cylinder of the front caliper, with a run of more than 50-70 thousand km, the brakes can wedge. The repair kit will cost 400 rubles. Sometimes the rear brake cylinders begin to "poison" the brake fluid.
The Geely MK body does not resist corrosion well. The first foci inevitably appear on the chips. And after 1-2 years of operation in the lower corner of the front doors under the seal, in the area of the trunk lid lock, gas tank hatch and on the inner surface of the hood. Headlights and taillights often fog up, and fog lights often break when used in cool, damp weather.
The hard plastic of the Geely MK interior is very creaky, especially in cold weather. Rattle in the steering wheel may appear due to the screws that hold the airbag unit loosen over time. A loose steering shaft seal increases engine and exhaust noise in the cabin. One of the problems of Geely MK is the water in the cabin. It gets there because of poorly glued windshield and rear windows and through flying rubber plugs on the bottom. Water in the trunk accumulates due to the rear light mountings and rear shock absorber mounts. Also, water can enter through the ventilation valves.
A lot of complaints are caused by the operation of the air conditioning system. The air conditioner becomes ineffective at an ambient temperature of more than 25-30 degrees Celsius. This is facilitated by the design feature of the heating system: hot pipes and a heater radiator are located directly under the panel. Even in cool weather, with the air conditioner turned off and the temperature controller in the cold sector, warm air comes out of the deflectors. With a run of more than 100 thousand km, leaks in the air conditioning system become more frequent. The air conditioning compressor can jam with a run of more than 50-100 thousand km. A new compressor will require about 9-12 thousand rubles. The heater fan may stop turning on or change the rotation speed due to the failure of the relay (rheostat) of the fan speed controller. The new regulator is not expensive - about 400 rubles.
Problems with the charging current may appear with a run of more than 80-120 thousand km. Cause voltage regulator failure. A set of a new relay and brushes will cost 2.5-3.5 thousand rubles. A new generator costs about 4.5-5.5 thousand rubles.
Due to the short circuit of the temperature sensor of the heating element of the seats or the “sticking” of the button for turning on the heating, the heating of the front seats may stop working. Factory heating elements for mirror heating do an excellent job, but they often fail. After replacing the mirrors with an analogue, the heating becomes not so effective, but it is much more durable.
With a run of more than 100-150 thousand km, a break in the stalk loop of wires is possible. There are frequent problems with the illumination of the dashboard. The reason is the failure of the microcircuit of the driver board of the electric motors that control the movement of the arrows and the backlight of the devices. The cost of a new tidy is about 7-8 thousand rubles.
