What is the reason why the auxiliary water tank of automobile is often short of water?

1, water pipe joint, water pipe itself leaks, replace the water pipe or strengthen the seal.

2. The cylinder block is cracked, and the cylinder head gasket is lax or damaged, resulting in water cross-flow.

3. The oil radiator sealing ring is damaged or has sand holes, resulting in cross flow of water.

4. The water tank cover is not tight.

5. The heater water tank leaks.

6. The tee leaks.

It is abnormal that the auxiliary water tank has no water. If the water pipes and water tank covers of the main water tank and the auxiliary water tank are connected normally, the main water tank of the automobile will absorb water from the auxiliary water tank without water. It is enough to keep half of the coolant in the auxiliary water tank, but it is impossible without water.

Matters needing attention in the use of water tank:

1, first of all, remind safety, please don't open the water tank cover directly when the water tank is boiling, steam and boiling water will cause personal injury.

2. According to the situation described, it seems that the water circulation is abnormal, otherwise the temperature of the upper water pipe should be higher.

3. If the effluent is basically normal, insert the nozzle into the water to see if there are a lot of bubbles coming out. If so, the cylinder gasket may be flushed. Adjust the ignition advance angle.
