Nangyari na kasi sa akin yan sa dati kong Chevy cavalier broTS, bago na lahat, radiator,thermostat,cooling fan,water pump...overheat pa din..

Cylinder head gasket na pala....after mareface at palitan ang gasket, ok na siya.....

Goodluck na lang...

The heater cools down the coolant because coolant is what goes through your heater to heat the car.

If all the hoses are new and the radiator is not leaking and you're still losing water, it might be the cylinder head, but I'd get a compression and leakdown test to find out for sure.
