The timing kit includes:

• toothed belt
• tension roller
• guide roller
• water pump (if driven by the timing belt)

More information about timings:

The time for replacing the timing belt or the timing drive kit is given in the car’s owner’s manual.

In most cases, the timing belt is replaced every 40,000 – 80,000 miles

In used cars with unknown mileage or newly purchased cars, we recommend replacing the timing kit, especially in the absence of service documentation.

The timing is a system used to control the opening and closing of the valves in a four-stroke engine (this is rare in two-strokes). It is a very precise and one of the most important mechanisms in the engine.

The drive from the crankshaft is transferred to the camshaft, usually using a belt or chain, but there are also timing gears driven only by gears. Valves open and close at specific times.

If these functions are not synchronized, the engine will either not start at all, or will run erratically, and serious engine damage may occur. As technology progresses, solutions are more and more often used that, within certain limits, allow changing the valve timing, i.e. shifting the moment of opening and closing the valve, and sometimes even changing the valve lift.

This is achieved by the increasingly popular electronically controlled devices inside the heads or at the cams of the rollers. Such solutions (e.g. VTEC in Honda or VarioCam Plus in Porsche) increase engine efficiency and its ability to work at high revs, and above all, increase its performance without supercharging.

Breaking the timing belt causes a very serious engine failure as a result of the pistons colliding with the valves, which can cause the bending of the valve stems, and damage to the pistons, and valve guides.

To transfer the torque from the crankshaft to the camshaft, gears, chain or belt transmissions using a toothed belt are used. The last solution does not require lubrication, is wear-resistant and does not overload the bearings. It is most often used in modern cars. During operation, this belt is subject to many millions of variable stresses, temperature changes and wear as a result of friction with cooperating elements.

A broken belt causes very serious engine failure due to the pistons hitting the valves, which can cause bent valve stems, damage to the pistons, valve guides, etc. Understandably, repairing an engine after such a failure is very expensive.

These types of failures occur either as a result of not meeting the timing belt replacement interval specified in the owner’s manual, or, rarely, a manufacturing defect in the belt. Peering into the engine compartment of modern cars won’t help much as even the belt cover is often invisible. You can only listen to the operation of the engine and pay attention to whether there are any strong and disturbing noises coming from the vicinity of the belt – “torn” belt elements can cause noise by rubbing against engine elements or covers. In this case, you can take it as a signal and prevent a serious failure. When buying a used car, the documents of which do not show when the belt was last replaced, it is better to incur the additional cost and replace the belt.

Breaking the timing belt always causes the immobilization of the engine, and in many cases also its destruction. Unfortunately, even strict adherence to the replacement dates recommended by the manufacturer will not necessarily protect us from failure.

The timing belt is a toothed belt made of rubber that drives the camshaft. Its durability is limited, so it must be regularly replaced. However, many belts do not withstand the mileage assumed by the manufacturer. One of the reasons is the lengthening of the mileage. Just a few years ago, it was recommended to replace the belt every 40-60 thousand km. miles

Currently, practically all companies have extended their mileage to 120,000. kilometres and even more. Therefore, in order not to repair the engine at your own expense, it is better to replace the belt earlier, because in most petrol engines and all diesel engines, breaking the belt practically destroys the engine. Both valves and pistons need to be replaced, and in addition, in some engines, the camshaft and shaft mountings are also broken. In this case, the motor head is only suitable for replacement.

Unfortunately, observing the timing of belt replacement by the manufacturer’s recommendations does not guarantee that the belt will not break. In addition, it can happen 10, 20 or even 40 thousand. km before the scheduled replacement! Therefore, it is better to consult the mileage after which the belt should be replaced by mechanics servicing a given brand, who should know what is the safe mileage for a given engine.

Belt durability

Belt durability depends on many factors. The main ones are the driving style of the driver and the conditions of use.

Significantly higher loads due to frequent accelerations and braking, and thus faster wear of the belt occurs during city driving. In addition, standing in traffic jams, the engine is running, and the miles on the counter do not come.

The timing belt also ages and should be replaced after three to a maximum of five years of operation, even with low mileage.

The belt should also be replaced after buying a used car if we are not sure when it was replaced.

The belt is also suitable for replacement when it was flooded with oil.

It is not worth saving on the belt, it is better to choose a more expensive, but reputable company. Then we have a quality guarantee.

Not just a belt

When replacing the belt, it is also necessary to replace the tensioners, other timing elements and the water pump, which in most engines is driven by the timing belt, even if they do not show wear. It is also worth carefully checking the condition of the seals.
