Antifreeze can prevent the coolant from cracking the radiator and freezing the engine cylinder block or cover when parking in cold winter. Many people think that antifreeze is only used in winter, but it is actually used all year round.
High-quality antifreeze is replaced once a year, and those cars with short running time can be replaced once every two years or 30 thousand kilometers. In order to prevent excessive foam and reduce the heat exchange between non-freezing liquid and engine parts, confirm that the product is within the validity period when adding.
Extended data
Before completely replacing the antifreeze, it is necessary to conduct a comprehensive inspection to see if there are any signs 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. The antifreeze is distributed to different parts of the car after flowing through the five-way water pipe. If there is antifreeze leakage in this part, replace the water pipe or re-fix the interface according to the situation.
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 from the pitcher is a little pink at first. Continue to inject clean water until the water is clean. Be careful not to forget to remove the heating water pipe and clean the water in the heating water tank.
