Replaced my leaking water pump today (Balmy 32 degrees today.. awesome) got it on OK, ran up to temp. top hose gets hot bottom stays cool. is my T stat stuck? Gauge shows normal temp.

or is this pump not p u m p i n??

 

I would replace the thermostat and check from there.

 

That's what I was thinking.... but why would it not overheat if the T stat was staying closed?

 

well it might be broke and allowing only a little bit through just enough to keep it from overheating.

 

Yeah. Well they are cheap and I'm sure it needs replaced anyway.

 

Let us know how it goes.
