Timing kit replacement

Timing belt (gas distribution mechanism) is an important part in any car that ensures constant exhaust and intake of gas flows into the cylinder of an internal combustion engine. Like any timing mechanism, it requires timely replacement.

Cars of different brands have individual qualities that distinguish them from others. Depending on the manufacturer, the timing belt has a certain service life. But most manufacturers recommend replacing it at least every 50-60 thousand km. This mechanism performs important functions of maintaining the car in working condition. For example, the timing belt is needed for:

• Ensuring the synchronism of the engine valves and pistons.
• Forces the water pump to operate.
• Ensures reliable operation of the oil pump.

The timing chain is the connecting link between the upper part of the engine (cylinder head and valves) and the lower part of the engine (pistons and crankcase). It transmits torque from the crankshaft to the camshaft. The intake and exhaust valves open and close synchronously, at certain intervals at each engine revolution.

Thus, the correct synchronization of the crankshaft and camshaft, which is guaranteed by the chain, ensures the correct operation of the engine, its power and economical fuel consumption.

How to understand that the timing chain needs to be replaced?

Good and high-quality operation of the engine directly depends on the timing system. It operates under heavy loads and it is not surprising that after several thousand kilometers the timing chain needs to be replaced. Wear and the need for urgent replacement can be determined by several factors:

• There is constant noise and creaking in the engines. If you hear unpleasant sounds while driving, you should urgently contact the masters.
  
• Idle speed has increased significantly and when the engine is started, noise is clearly heard.
  
• The pressure in the engine has increased significantly and the pipes have become more elastic.
  
• When diagnosing the timing system, worn sprocket teeth are visible, as well as poor chain tension

Visual diagnostics of the timing belt at home is not always possible, since this mechanism is usually covered by a protective casing. Therefore, when the first signs of wear appear, it is better to seek help from the VAG Master car service network.

The best way not to miss critical belt wear is to follow the manufacturer’s recommendations. It is recommended to replace the timing belt after 50-60 thousand kilometers. The exact mileage depends on the specific make and model of the car.

You can independently monitor when replacement is required only in the following cases:

• you know when this element was last replaced;
• a high-quality and original belt is installed, which is guaranteed to serve its intended purpose;
• the internal combustion engine operates without interruptions;
• the motorist does not overload the engine and does not create emergency situations for the engine;
• the car owner uses only high-quality fuel.

You should rely not only on the recommendations from the service book, but also make sure that your car is working properly.

If not replaced on time

If the chain is not replaced on time, “jumps” occur. As a result, the engine starts to work intermittently and all the consequences of such work are difficult to predict.

If it breaks at low engine speeds, the chain can only slip off the pulleys without causing serious damage. If the car’s speed is high, the chain breaks into several pieces and damages the inside of the engine. In this case, to fully restore the engine, expensive repairs will be required, which sometimes exceed the cost of six months of operation of the car.

After what mileage should the timing chain be changed?

Expert opinions differ. Some say that you need to follow the instructions in the technical documentation, others say that you should reduce the mileage, taking into account the climate and road conditions. Still other engineers say that there are cars that can easily “travel” 250 thousand km without replacing the chain, while on other brands, replacement will be required every 60-80 thousand km. Frequent oil changes and adjustment of the valve timing increase the service life of the chain.

But still, you need to look at the specific engine and operating conditions. The only thing that car mechanics agree on is that a well-maintained car, whose owner undergoes timely maintenance, changes the oil, and regularly monitors the systems, does not get into trouble from
