Kia Rio when to change the timing belt. Removing, replacing and installing the timing chain Kia Rio III When to change the timing for Kia Rio 3

The reliability of the operation of each car directly depends on the state in which it is. A car will never let you down on the road if its technical inspection is carried out regularly, and consumables are changed on time. You can change some parts of the car yourself, but for this you need to have at least an initial idea of ​​\u200b\u200bits device. Here we will talk about how you can change the timing drive to Kia Rio 1.6 yourself.

The gas distribution unit serves to remove exhaust gases and to ensure that air enters the cylinders. The air mass enters the cylinders due to the cyclic opening and closing of the valve system. This is possible due to the work of the shafts, which are connected by a drive. Some Kia Rio models use a chain as a drive, while others use a belt. Let's take a closer look at this.

Chain resource

Of course, the chain is more durable, as it is made of solid metal, and the belt is made of rubber, albeit of high quality. Metal, by definition, lasts longer. The chain tension is provided by a hydraulic tensioner. This mechanism is automatically lubricated with oil, as it is located inside the propulsion system. The chain can be operated up to 300,000 km, but over time it can stretch, so it is highly recommended to diagnose it at least after 40,000 km. If there is play between the links, the chain will stretch. This can lead to the consumable coming off the sprockets, and then serious repairs cannot be avoided.

The belt is made of rubber alloy, and has a serious wear resistance. The belt is no longer built into the engine, but outside it. The belt drive is tensioned on gears, which are protected by a plastic cover. You have to change the belt more often than the chain, you need to do this after 150-170,000 km. But the need to replace it may arise much earlier. This is influenced by a number of factors, the main of which is driving under increased loads. If you use a trailer, then you should be in the belt drive condition more often, as its use wears out the belt a lot. But increased loads are not the only factor affecting premature wear. Aggressive driving is also important. In this case, the belt also wears out faster. In this aspect, one can also mention extreme weather conditions. In severe frost, the belt freezes, and while driving it has to experience strong friction, this also affects wear. Finally, engine oil can get on the belt. This happens when the stuffing box has lost its tightness and started to leak. In this case, it will also need to be replaced along with the belt drive. If this is not done, then the engine oil will continue to drip onto the new consumable. From this he definitely will not be healthy, as the oil corrodes the rubber.

But what external signs will indicate that the belt has already worn out enough and needs to be replaced with a new one:

• the outer and inner surfaces look clearly worn;
• the sides are frayed and separate threads stick out of them;
• the material began to delaminate;
• cracks and bulges are visible on the surface;
• oil stains.

The above was about the chain. So, its main advantage is the fact that it never breaks. Unfortunately, the same cannot be said for the belt. If you do not monitor its condition, then it can wear out a lot, as a result of which it breaks. In this case, the car will receive serious damage, after which serious repairs will be necessary. Judge for yourself, as a result of a broken belt drive, the valves will collide with the pistons and bend. Other parts of the assembly will also receive damage, so it is better not to bring it to a break. It is necessary to check the condition of the belt from time to time and change it if necessary.

You can also replace the belt drive yourself. Every motorist who follows the instructions can do this. To carry out such repairs, it is necessary to prepare the necessary tools and new consumables. Here's what we might need:

• a set of keys;
• set of heads;
• screwdrivers with different tips;
• pliers;
• jack;
• shaft lock;
• torque wrench;
• new drive;
• a set of seals;
• gasket set;
• new tension roller (if necessary).

Replacement process

1. Remove the front wheel from the motor side;
2. Weaken and remove the tension belts of mounted units;
3. Remove the clutch housing cover. To do this, you will also have to unscrew a few bolts.
4. Matching labels. To do this, turn the crankshaft 2 turns to the right.
5. We fix the crankshaft so that it does not scroll. To do this, you can use a special latch, or you can get by with a regular screwdriver. It is inserted between the crankcase and the teeth. Loosen the crankshaft pulley bolt.
6. Now we dismantle the pulley.
7. Remove the spacer to expose the crankshaft sprocket.
8. We remove the pump.
9. After unscrewing a few bolts, remove the lower casing.
10. We check the alignment of labels. The mark on the camshaft gear must align with the mark on the cylinder head.
11. We set aside the tensioner, after unscrewing the fasteners.
12. Remove belt drive. If it is not removed for replacement, then marks should be placed on it that will indicate the direction of its movement.

13. Before installing a new consumable, we check that the mark on the camshaft sprocket matches the mark on the cylinder head.
14. It is worth starting to tighten the gear from the camshaft gear and then counterclockwise.
15. We let the automatic tensioner work by loosening the bolt of its fastening.
16. We tighten all the bolts and check the tension of the belt drive. It should be optimal - without sagging and pulling.
17. Once again we check all the marks and begin to assemble the mechanism in the reverse order.

After the procedure for replacing the belt drive, you need to check the operation of the engine. Plug it in and listen to how it works. If there is extraneous noise, everything will have to be done again.

Replacing the timing belt Kia Rio is one of the most important car maintenance activities. The gas distribution mechanism (GRM) is a control system for opening and closing valves in the engine cylinders. The timing drive transmits the driving force between the camshaft and crankshaft in the car engine. In some engines, a chain is used instead of a belt, which, as a rule, increases their reliability and increases the service interval. Many owners do not know what type of drive is installed in the Kia Rio engines with a chain or belt. We will help answer this question. In Rio 2 engines, the timing mechanism is controlled by a belt. Its resource is 50-60 thousand kilometers, or 3 years of service. We recommend checking its condition every 15 thousand kilometers and if you find visible damage or loose tension, you should immediately adjust it or replace it.

The motors of the third generation machines use a chain. The timing belt on the Kia Rio 1.6 has not been used since 2011. This also applies to the 1.4 liter engine. So why is it so important to monitor the condition of this part and change it in time? Over time, the material from which the belt drive is made tans and stretches, cracks appear on it. This could threaten to break it. On 16-valve DOHC engines that are installed on many modern cars, a situation may arise when, when the belt breaks, the pistons meet the valves, which leads to the bending of the latter. As a result, the motor needs an expensive overhaul. To prevent this from happening, you need to keep the Rio timing drive in proper condition.

We remind you that the repair of the engine, as well as other complex vehicle systems, must be carried out by specialists in a specialized service center using special equipment and original parts (or their high-quality substitutes), but if you have experience in repairing such systems and the necessary tools, you can perform this work and yourself.

Kia Rio do-it-yourself timing belt replacement

Observe safety precautions during work. Experts, together with the belt, recommend replacing the tension and support rollers. Although the replacement of the Kia Rio roller is less often required, you will not have to carry out a complicated procedure if they fail.

1. 1. Remove the negative cable from the battery
   2. Remove auxiliary and drive belts
   3. Disconnect the generator
   4. Remove pump and crankshaft pulleys
   5. Remove the belt guide plate
   6. Dismantle the upper and lower casings of the Kia Rio timing belt

1. Install the crankshaft so that the timing mark is aligned with the delay time mark on the engine
2. Make sure that the I and E mark on the camshaft pulley is aligned with the mark on the cylinder head.
   NOTE! Do not move the shafts after the marks have been correctly set.
3. If the timing belt needs to be put back, mark the direction the timing belt used to rotate
4. Remove timing belt tensioner
5. Remove timing belt drive

Installation:

1. Replace the timing belt tensioner pulley, move the tensioner to the farthest point and tighten the mounting bolt
2. Install the timing belt on the shaft pulleys and rollers
3. Loosen the tension roller and let the tensioner springs become the position that will create the optimal belt tension, then tighten the fastening bolt with a torque of 38-51 Nm
4. Rotate the crankshaft clockwise 2 turns and check that all marks are still properly aligned
5. Install the remaining components in reverse order, tightening the mounting bolts with the following forces: crankshaft pulley - 12-17 Nm, water pump pulley - 12-17 Nm
6. Connect negative battery cable

This completes the replacement of the belt, you can not be afraid of the consequences of its breakage. The Kia Rio chain also has a significantly longer resource, but it also undergoes stretching over time, especially with an aggressive driving style. It must be changed, as recommended by the manufacturer, every 170 thousand kilometers or 12 years, regardless of mileage. In one of the following articles, we will consider this procedure.

The reliability of its operation depends on the technical condition of the parts and components of the car. With regular inspection and timely replacement of consumables, the car will not let you down on the road. To replace spare parts yourself, you need to know the internal structure of the machine and the parts that need to be replaced. The article discusses what is installed on the Kia Rio: or the chain, and also provides a comparative analysis of both consumables and a description of replacing the timing belt with the Kia Rio.

Which is better: belt or chain?

The gas distribution mechanism on the Kia Rio is designed to supply air to the cylinders and exhaust gases. Air enters by opening and closing the intake and exhaust valves. The whole process is carried out using a camshaft and crankshaft connected by a chain or belt. What are the pros and cons of the strap and chain?

The main advantage of the chain is durability. The chain is more reliable than the belt, as it is made of metal, and metal has a much longer service life than rubber. The chain is put on the timing sprockets. Constant tension is provided by a hydraulic tensioner. The mechanism is located inside the engine, so it is constantly lubricated with engine oil.

The service life of the product is on average 150-300 thousand kilometers. But during operation, the chain stretches over time, so every 70 thousand km it is necessary to do a timing inspection. If play is detected, the tensioner must be changed, as jumping over the teeth is possible, which can lead to serious repairs. If play remains after replacing the tensioner, the chain must be replaced.

A belt is a cheaper design, but less reliable than a chain. Although modern timing belts are made of a rubber alloy that is resistant to wear. The belt drive is similar to the chain drive, but is located outside the engine compartment. The strap is pulled not on the sprockets, but on the shaft drive pulleys, which are displayed on the front panel and protected by a plastic casing. Belt replacement is performed approximately twice as often as chains: every 70-150 thousand kilometers.

Thus, we can conclude that the chain is more reliable than the belt. A strap is installed on Kia Rio cars of the 1st and 2nd generation, but the chain is more reliable, so a chain drive is installed on all versions of the 3rd generation.

In what cases is a replacement necessary?

Although the chain is heavier and the chain mechanism has additional parts, this does not affect the reliability of the mechanism. It is recommended to change the chain for Kia Rio as it wears out, after about 180 thousand kilometers or after 12 years of operation, it depends on which comes first. Can be replaced during engine overhaul.
The belt has to be changed every 60 thousand km. But the main replacement criterion is a visual inspection. Replacement is performed when the following defects are found:

• wear of surfaces, both internal and external;
• frayed side edges;
• delamination of material from the base;
• cracks, tears;
• traces of engine oil.

One of the advantages of the chain is that it will never break. If the strap breaks, the valves can bend and the pistons can be damaged, which will require an engine overhaul.

Step by step replacement instructions

It is convenient to perform replacement work on a viewing hole, lift or overpass. The car must be put on the hand brake and fix the wheels to prevent the car from moving.

Tools

From tools and materials it is necessary to prepare:

• a set of spanners and heads;
• set of wrenches;
• flat screwdriver;
• engine mounts;
• torque wrench;
• jack;
• consumables (belt, tension roller).

Repair kit for Kia Rio

You should purchase only original consumables, this will save you from unpleasant surprises due to low-quality parts. If traces of oil are the cause of the replacement, the cause of the stains must be eliminated.

Stages

1. First, the front right wheel is removed, then the protection on the right side of the engine.
2. The next step is to remove the drive belts from the attachment by loosening their tension.
3. Having unscrewed the mounting bolts, you need to remove the clutch housing.
4. After turning the crankshaft clockwise, it is necessary to align the alignment marks.
5. Next, loosen the crankshaft pulley mounting bolt. To do this, you need to fix the crankshaft from turning, for example, using a flat screwdriver, inserting it between the crankcase and the teeth.
6. After that, completely unscrew the mounting bolt together with the washer and remove the crankshaft pulley.
7. To open the shaft gear, you need to dismantle the spacer.
8. Next, you need to dismantle the pump.
9. Then you should unscrew the fixing bolts and dismantle the lower protective cover.
10. Next, you need to check that the sprocket on the camshaft is aligned with the cylinder head alignment mark.
11. After loosening the tension bolts, you need to take it to the side and tighten the bolts a little.
12. Next, remove the timing belt. When reusing the product, marks should be put showing the direction of its rotation.

Timing without protective cover

Installation:

1. Before installation, you need to check the alignment of all installation marks, as well as the sprocket on the camshaft with the mark on the cylinder head.
2. The belt tension should start from the crankshaft gear in a counterclockwise direction.
3. After loosening the tension roller bolt, you need to let it work.
4. Then tighten the tensioner bolts with a force of 20-27 Nm.
5. Next, you need to check the tension of the strap.
6. Then check the alignment of the marks again.
7. Assembly must be carried out in reverse order.

After completing the timing belt replacement procedure, you should check the performance of the car.
