How to Replace Coolant for BYD F3?
2 Answers
Method for replacing coolant in BYD F3: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage in the pipelines. Drain the old coolant, then flush the liquid channels with clean water. After draining for about an hour, add the new coolant through the radiator hose to allow the coolant to flow quickly into the radiator. Can different coolants be mixed: Only use the same brand of coolant.
I've changed the coolant for my BYD F3 several times before. The procedure isn't difficult but requires safety precautions. After turning off the engine, wait at least one hour for it to cool down, otherwise there's a high risk of burns from hot liquid. Locate the radiator drain plug or reservoir drain plug in the engine compartment, use a wrench to open it, and let the old coolant flow into a catch pan. The BYD F3 typically uses green or red coolant. After preparing new coolant, I first flush the system - add some clean water and run the engine for a few minutes to rinse out rust and deposits, then drain completely. Next, pour new coolant up to the MAX line, start the engine to let it warm up, and the coolant level will drop after the fan circulates - top it up to the proper level. Finally, close the air bleeder valve and ensure there are no leaks. Remember to change it every 2 years or 30,000 kilometers to protect engine components.
