My antifreeze seems to leak out only when I am driving. It does not leak out when the car is off. If I drive the car for a few miles two days in a row then by the end of day two the antifreeze is all gone. When the car was running hot while I was driving it was making a hissing noise not sure the problem. I also put liquid copper in the radiator about a week and a half ago because my radiator was losing coolant but it was losing it like once a month now it is more frequent.

Good evening.

The sealers do not work. They tend to clog up the radiator and the heater core.

The system will need to be pressure tested to find the source of the leak. Once that is determined, then repairs can be made to correct the leak.

The hissing is the cooling system leaking.
