Does Chevrolet Lafont have a drain valve in its water tank? How to change antifreeze?
Main answer
1. When the car is cold, open the lid of the antifreeze pot, reach the left side of the water tank (co-pilot side) with your arm, unscrew the black plastic screws at the drain with a wrench of 12MM, and empty the original antifreeze. Pay attention to the container that receives and discharges antifreeze, because it will pollute the environment!
2. Rinse the lower pipeline with clear water, then drain it, screw on the screw of the drain, add the cleaning agent for the cooling system, then add a proper amount of water to the normal level, start the vehicle, and clean the cooling system at idle speed for 10~ 15 minutes.
3. After cooling, repeat step 1.
4. Rinse the cooling system continuously with clear water until the discharged water is clear and foam-free.
5, start the car, idle running for 3~5 minutes, using heat to dry the residual moisture in the system.
6. Tighten the screw of the drain, add new antifreeze to the maximum liquid level, start the car, the liquid level drops, and continue to add until it reaches the normal liquid level.
