Hi,

So the coolant drain into the resolvor reserve bottle, but would not return it back to the radiator when it's hot. I have to keep adding antifree and empty the bottle almost everyday. I had change a new radiator and new cap. Also changed a thermostat on it. Still having the problem of losing antifree into the resolvor bottle. Any idea what esle could it be? Thank you

Hello,

The coolant is going somewhere. Does your vehicle exhibit a lot of white smoke? If so this would indicate a blown head gasket. Usually how a cooling system leak is diagnosed is to do a cooling system pressure test. Here is a link below explaining how to do this:

Please go through this guide and get back to us with how everything turns out, or what you are able to find out.

Thanks,
Alex
