1. Poor fan switch;
2. Poor radiator cap;
3. Poor thermostat;
4. Too little coolant;
5. The water pipe or water pipe sleeve is
blocked;
6. The radiator blade is blocked;

Inspection of performance
Inspection of radiator cap
Warning:
Make sure the coolant is completely cool
before opening the cover.
Install the radiator cap on the radiator
detector to increase the pressure of the
pump. If it can be maintained within the
The water temperature does not rise or
does not rise well
1. Poor fan switch;
2. Poor thermostat;
3. The cable is short circuited.
Water leakage
1. Poor mechanical seal;
2. Deterioration and poor adhesion of O-
rings;
3. Damage and deterioration of water pipe.
Radiator detector
Radiator cap
Inspection of radiator pressurization
Install the radiator detector on the radiator,
increase the pressure of the pump, and
confirm whether it can be maintained
within the specified pressure range for 6
seconds.
