[Ramblin Fever]

Just went through some cooling system issues myself - in regards to a radiator flush with the installation of new hoses and a thermostat. 2 days later, we found one of the clamps not tightened down on the lower radiator hose - didn't overheat, but was peeing a lot of green juice.

A week later my waterpump went out, had 90k miles on it, and it didn't give but a half days warning - had it towed to town where they fixed her up, this whole time the truck did not overheat, although the radiator was sucking in antifreeze from the reserve, leaving the reserve dry, but the radiator was always full.

I wonder if it didn't overheat because Colorado was in an artic freeze that whole week.

Couple of things - it is always possible to end up with a bad thermostat, stuck in the closed position; another thing is clamps can prove to be weak even when they're new.

Are you dripping antifreeze anywhere?
