radiator?

Another prob. nothing leaks but I filled up the radiator and ran the motor all day and now the overflow is fillin up with the coolant I put in. Is it suppose to do this because now I have to fill the radiator up and it will do the same thing. I dont know if this makes any sense, if it doesnt tell me and ill make it clear.

is it bubbling? cuz if its gettin too hot dont drive it till you fix it! could be simple as a water pump or a radiator or worse a head gasket, but the hg on these is pretty simple

I would probably lean towards the water pump not flowing the coolant

I disagree. The water pump is going to continuously be flowing coolant regardless, it's driven by the timing belt. The ONLY 2 ways that it wouldn't circulate coolant was if the impeller disintegrated completely, and that's not very likely. The other way would be if there is a MAJOR restriction.

I am leaning towards either a seized thermostat or a bad head gasket. It is very easy to get a bad head gasket on these motors. FIX IT QUICK BEFORE YOUR HEAD GETS WARPED!!! It's happened to me twice in the past (once by a bad mechanic and the other on a long return trip Tampa-Atlanta.)
