How to Bleed the System for High Engine Temperature?

[LaMaya]

Here are the specific methods for bleeding the system when the engine temperature is too high: 1. If the temperature is excessively high or the temperature warning light keeps flashing, stop the vehicle to check whether the coolant level in the radiator is normal and inspect the radiator, hoses, and all connections for leaks. If no abnormalities are found during the visual inspection, refill the coolant as required and continue driving. If the temperature remains high after driving for a while and the coolant level drops upon stopping to check, this is likely due to a sand hole or perforation in the cylinder block's water jacket causing leakage. Upon discovering this issue, repairs should be carried out. 2. When the engine temperature is too high, you can touch the upper and lower radiator hoses to determine the fault. If there is a significant temperature difference between the two hoses, it can be concluded that the thermostat is not functioning. 3. If there is air in the cooling system, it can create an airlock, hindering proper coolant circulation and leading to high engine temperature. Run the engine at high speed and gently loosen the radiator cap until gas begins to escape. Some coolant may escape with the gas. Repeat this process several times until all the gas is released. After resolving the issue, promptly replenish the coolant. 4. If the vehicle has been driven on dirt roads or muddy sections for an extended period, debris may accumulate on the radiator, which over time can impair cooling efficiency and cause high water temperature. First, use compressed air to blow out the radiator grille, then rinse it with a water hose.
