During the National Day, an auto repair friend of the editor found that there was an oil leak in the front of the engine when he was maintaining Hyundai Tucson. Further inspection found that the cause of the oil leakage was that the front oil seal of the camshaft was not well sealed, and there was a very serious problem. The timing belt was damaged! If the timing belt is not changed, it may break at any time, which will seriously affect driving safety. This made the car owner very scared and directly agreed with the master's suggestion to replace the timing belt suit.

Next, we will take a brief look at a group of pictures taken by the master!

As shown in the figure below, the mileage of this Hyundai Tucson has exceeded 150000 kilometers, and the owner said that he has never changed the timing belt!

As shown by the arrow in the figure below, there is oil leakage at this position. It is located on the timing housing at the lower part of the camshaft. Only the cooling fan, water tank, anti-collision beam and front bumper at the front of the engine can be repaired.

As shown in the figure below, this is a part of the parts removed by the master. A box is not enough. As shown by the arrow, this is the cooling fan of the engine water tank, a relatively old silicone oil fan.

According to the master, special tools are needed to disassemble the timing belt suit of this engine.

As shown in the green area in the figure below, the special tool has caught on both camshafts.

This is shown in the green area in the figure below. This is the location of the damage on the timing belt.

The master said that the owner has never changed the timing belt. Since the timing belt has been wrapped better, the aging situation is not obvious, but it must be changed now.

As shown in the figure below, the master has removed the upper part of the timing belt shell, so that you can see it more comprehensively.

We can see that there are many cracks on the timing belt, and each crack may break. The consequences of a broken timing belt are still quite serious. The engine has to be disassembled and repaired, which makes the owner very scared!

At the same time, the auto repairman checked the chassis of this modern tucson, and there were many problems!

As shown by the arrow in the figure below, the shock absorber has serious oil leakage and has failed to play its due role. Absorbed noise will occur when driving on uneven roads. It is recommended to replace it. And the stabilizer bar small connecting rod installed on the shock absorber has also had problems and needs to be replaced!

After the auto repair master inspected the entire Hyundai Tucson, it is recommended that the owner replace the timing belt suit (including timing belt, tensioner and idler), generator belt, two oil-leaking shock absorbers, and stabilizer bar. Small connecting rods and rubber sleeves, as well as various oils, etc.

After half a day of maintenance, the master replaced all these parts.

As shown in the figure below, these are the parts replaced by the master. The orange area shows the timing belt suit, and the arrow shows the generator belt, etc!

Let's take a look at the new timing belt.

The green arrow in the figure below shows that this is the new timing belt, and the orange arrow shows that this is the old timing belt. The difference is very obvious!

Finally, after the auto repair master changed the timing belt, he started the engine and everything was normal!

Through this maintenance case, what our car owners should know is: if the engine is a timing belt type, when the mileage is more, don't forget to check the status of the timing belt when maintaining the engine, and replace it when it should be replaced. Don't be like the Tucson owner in this repair case, just maintain the engine every time and never check the timing belt.

I hope this repair case can help the car friends!
