Re: Radiator Overflowing At Normal Temperature..
Just to be sure, when you fill a system
1 - fill it to the top
2 - run it at idle with the cap off until the thermostat opens and it sucks a bunch in, it'll breathe and burp then just drop like a rock
3 - top it off and put the cap back on
If it doesn't drop, thermostat could be bad or backwards, if it continues to build pressure not just heat expansion, but like a compressor, it's a bad head gasket
