Precautions for use of equipment

Revo classroom

01
Factors causing high engine temperature

1.Water tank cover、The engine cylinder head is damaged

2.Insufficient or deteriorated coolant

3.The radiator and exhaust pipe are blocked.

4.Insufficient or deteriorated oil、Fuel quality is not up to standard

5.Too much fuel is injected、Incorrect fuel injection

6.Insufficient tension of fan belt

7.Water pump、Thermostat、Faulty fan clutch

8.Low initial injection pressure

02
Troubleshooting skills

1. When the engine is hot，First, confirm the authenticity，Confirm the actual temperature of the coolant；

2. If false high temperature：Check the continuity of the water temperature sensor and the harness from the water temperature sensor to the engine controller.；

3. If it's really hot：Check from easy to difficult，Water tank cover→Coolant capacity、Quality→Exhaust pipe→Oil capacity、Quality→Fuel quality→Belt wear、Tightness→Inside and outside the radiator→Water pump→Thermostat；

Precautions

1.When servicing the radiator，Synchronously check whether the sponge falls off；

2.Verify fan blade to radiator clearance 10-15mm；

3.Use special coolant for Lovol，Do not mix or change the proportion of coolant.；

4.View the fan status，Leakage of water tank，Lack of coolant；

5.Clean the heat sink regularly，Maintain fan belt tension；

6.Check hood and side door sponges regularly for missing，The cabin is poorly sealed，The cooling air volume is insufficient，It can also cause high temperatures.；

7.Except for the reasons of the vehicle itself，Unconventional operations may also cause high temperatures，If there is any fault, a comprehensive inspection should be carried out first.，Do not repair blindly，Call 400 in time-8291-888 service hotline for repair。
