How to Solve High Water Temperature When Running AC in Haval H6?
1 Answers
Here are several solutions for high water temperature when running AC in Haval H6: 1. Insufficient coolant: Coolant leakage or low coolant level can cause engine temperature to rise. Check the coolant level and top up if necessary. Recheck after a few days for significant level drop, and locate any leaks if present. 2. Cooling fan malfunction: When the vehicle runs at high RPM, heat cannot be effectively transferred to the antifreeze, affecting heat dissipation and causing antifreeze temperature to rise, potentially leading to boiling issues. 3. Water pump failure: Common pump failures include seized bearings or damaged impellers. Seized bearings are rare, while impeller damage (cracking or loosening from the pump shaft) can slow coolant circulation, leading to engine overheating. 4. Thermostat failure: The thermostat automatically adjusts coolant flow to the radiator based on temperature, regulating the cooling system's capacity to maintain optimal engine temperature. A faulty thermostat may prevent the cooling system from entering full circulation mode, resulting in elevated water temperature.
