The difference between the leakage of Sega outlet chamber and the leakage of cylinder gasket.

When there is an abnormal phenomenon of decreasing antifreeze, water may leak. There are several reasons for water leakage, such as water leakage in the water outlet chamber, water leakage in the cylinder gasket, water leakage in the heater water tank interface (the symptom is water mark under the driver's foot pad), water pump leakage, water pipe aging leakage and so on. , but most of them are leaking from the water outlet room. If you see water or white crystals (antifreeze residue) at the joint between the outlet chamber and the water pipe and beside the cylinder gasket, it is water leakage. But it is almost impossible to judge whether the water leakage comes from the water outlet chamber or the cylinder pad.

Judging 1, only there is water in the engine oil or milk emulsifying phenomenon with engine oil in the water, or the exhaust pipe discharges a lot of water, and the coolant is very short; When the lid is opened, bubbles are constantly discharged: it can be judged that the cylinder gasket is leaking;

2. In most cases, it is impossible to directly judge whether it is the water outlet chamber or the cylinder gasket, but in fact, most of them are the problems of the water outlet chamber, and the possibility of water leakage of the cylinder gasket is very small. Therefore, both Peugeot and Citroen headquarters stipulate that in case of such water leakage, the outlet chamber must be repaired first. After maintenance, the owner can only carry out maintenance if he finds that the cylinder gasket is still leaking. On the one hand, this regulation prevents unnecessary waste in the warranty, on the other hand, it also prevents 4S from deliberately repairing the cylinder pad after the warranty is issued to cheat money, ruin the reputation of Shenlong and affect the sales of the model. But in fact, many 4S are said to be leaking in the water outlet chamber before the accident (in order to avoid major maintenance), and then they are said to be leaking in the cylinder gasket after the accident, as are many black-hearted repair shops and service stations.
