2. It can protect cast iron, brass, copper, aluminum alloy, solder and rubber parts.
It is compatible with any antifreeze and cooling water. Take care of the water tank and all cooling system components all the year round to protect your travel. Suitable for all kinds of automobile, ship engine water tanks and various industrial cooling water circulation systems. Note: Replace the new liquid and add new water from the water pipe of the water tank (radiator). This is the way to make antifreeze flow into the water tank quickly. Then add a bucket of water tank to the antifreeze tank until the antifreeze tank is almost full, and take a taxi for about 10 minutes. At this point, the liquid level of the cooling system drops due to the exclusion of some air, and then antifreeze is added and filled to the highest mark of the storage tank. Before checking the bottom and replacing the antifreeze, you should make a comprehensive inspection to see if there are any signs of leaks and cracks in each pipe. The key point is to check the five-way water pipe, which is named after the five interfaces connecting all parts. The water in the water tank is distributed to different parts of the car after passing through five water pipes. If this part leaks from the water tank, replace the water pipe or re-fix the interface according to the situation. Waterproof drain the old water tank, and then clean the liquid channel with clean water. Add clean water to the water tank, then inject clean water into the tank to make the clean 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 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.
