How to change Alfa Romeo antifreeze?

1. Inspection: Before the antifreeze is completely replaced, a comprehensive inspection is needed to see if there are any traces of leakage and cracks in each pipeline. The key point is to check the five-way water pipe, which is named after the five interfaces connecting all parts. After the antifreeze flows through the five-way pipe, it is distributed to different parts of the car to play a role. If there is antifreeze leakage in this part, replace the water pipe or re-fix the interface according to the situation.

Second, drainage: drain the old antifreeze, and then clean the liquid channel with clean water. Add clear water to the antifreeze replenishment tank, then inject 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 circulate water. The water in the pitcher is a little pink at first. Continue to inject clean water until the water becomes clean. Be careful not to forget to remove the heating water pipe and clean the water in the heating water tank.

Third, change the new liquid: after about 1 hour, add new antifreeze from the water pipe of the water tank (radiator), which is the way to make the antifreeze flow into the water tank quickly. Then add a bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and take a taxi for about 10 minutes. At this time, due to the exclusion of some air, the liquid level of the cooling system drops, and then antifreeze is added and the storage tank is filled.
