How to change Cadillac atsl antifreeze kettle;
1, first do a comprehensive inspection to see if there are cracks and leaks in the pipeline, with the focus on the five-way pipe (named because there are five interfaces connecting all parts). The antifreeze must flow through the five-way pipe and then be distributed to different parts of the car to play its role.
2. Drain the old antifreeze, clean the liquid passage with clear water, add the clear water to the antifreeze replenishment tank, then inject the clear water into the tank to make the clear water continuously flow through the engine cooling system, and then idle for 3 to 5 minutes to make the water circulate. The water from the water tank is a little pink at first. Continue to inject fresh water until the water is clean. Don't forget to remove the heater hose and clean the heater tank.
3. In order to make antifreeze flow into the water tank quickly, after draining for about 1 hour, add new antifreeze from the water pipe of the water tank (radiator), and then add a bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and ignite for about 10 minute. At this time, the liquid level of the cooling system drops due to the exclusion of some air, and then antifreeze is added, as long as the liquid level is the highest.
