How to Maintain a Car Cooling System?

[VanStephen]

Maintenance methods for a car cooling system are as follows: 1. Check the coolant: a. When cleaning the cooling system, if the engine is hot, do not open the radiator cap directly to avoid being scalded by hot water. Wait until the engine cools down, then open the radiator cap wrapped with a cloth. If there is residual pressure in the radiator, you will hear a venting sound when opening it, so take precautions. b. If the coolant is insufficient, add boiled water until it overflows, and try to avoid adding untreated water. If the coolant becomes dirty or full of scale, drain all the coolant and clean the cooling system. 2. Clean the cooling system: a. Simple cleaning. Drain the old coolant, fill the engine cooling system with clean water, start the engine and run it for 5 minutes, then drain the water. If the drained water is still dirty, repeat the above steps until the water is clear. b. Thorough cleaning. When the engine's heat dissipation performance is poor or there is excessive scale in the cooling system, use a dedicated radiator cleaner for cleaning.
