Throttle hose temperature is high

1, thermostat failure.

When the thermostat fails, after the engine water temperature reaches the target temperature, the thermostat switch cannot be turned on, and the thermostat is still closed. At this time, the water supply pipe will be hot and the water pipe will be cold.

2. The water temperature in the engine is low.

When the thermostatic switch is started, the coolant participates in the large-cycle cooling of the cooling system. When the engine temperature is lower than the target temperature, the cooling system is still in a small cycle state. The hot water pipe will be cooled.

3. The water pump is out of order.

The high temperature coolant of the engine enters the water tank from the thermostat. After the water tank is cooled, the engine is pumped back by the water pump to participate in the circulating cooling work. When the water pump fails, the pressure of the coolant in the water tank is insufficient, so it can't enter the body for cooling circulation, and there will also be cooling water pipes and hot water pipes. Matters needing attention in automobile water pipe maintenance:

1, no open flame

Car maintenance must be inseparable from gasoline and engine oil, which are flammable. Therefore, it is necessary to raise safety issues in automobile maintenance. Flammable and corrosive articles shall be stored reasonably according to regulations.

Step 2 keep it clean and tidy

Automobile maintenance is not a clean and tidy job, but even so, the staff should try their best to ensure that the ground in the maintenance area is clean and tidy, and clean up the spilled gasoline and engine oil in time, which is also for safety reasons. Moreover, a clean and tidy operating room is also convenient for maintenance personnel to carry out maintenance.
