How to Remove Air from the Radiator?

Start the vehicle and let it warm up for 5-10 minutes. Wait until the cooling fan starts running, then the coolant level will drop. Refill the coolant and close the radiator cap. To completely eliminate air from the radiator, ensure proper operation during the next coolant replacement. Below are the steps: 1. Open the engine compartment when the engine is cold and check if the coolant level is sufficient. There are MAX and MIN level marks on the side of the coolant reservoir. If the level is below the MIN mark when the engine is cold, add coolant according to the marks on the reservoir. 2. Inspect all connecting pipes for cracks and signs of leakage, with special attention to the five-way pipe. 3. Drain the old antifreeze and flush the liquid channels with clean water. Let the water continuously flow through the engine cooling system, idle the engine for 3 to 5 minutes to circulate the water, and continue adding clean water until the water coming out is clear. 4. Let the new antifreeze flow quickly into the radiator. After draining for 1 hour, add the new antifreeze through the radiator hose. Add another bottle of antifreeze to the antifreeze reservoir until it is full. Start the vehicle and let it run for 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Add more antifreeze until the level is between the two marks.
