Fault and analysis of the so-called fourth-generation golf maintenance of classic cars in recent years

1. The oil supply hose above the timing side in the engine room is prone to aging after a long time.

2. The high-pressure oil pipe of the steering booster, the pressure switch is easy to leak oil, and the low-pressure pipe is less broken.

3. The flange bakelite of the water temperature sensor on the battery side of the engine, commonly known as 4-way, is also easy to penetrate antifreeze. I recently bought an all-aluminum 4-way spare.

4. Warm air water supply pipe joint at the upper left of the brake booster drum

5. A complete set of cooling water pipes

6. Top glue and pressure bearing

7. Damping and cushioning glue
