I was having problems with my old T-stat sticking on me in the mornings. When I say old, it's really not old at all. Replaced it when I did the heads about 1000 miles ago; along with timing belts waterpump etc. etc.

 

So last night I bought a new t-stat along with upper and lower radiator hoses, put it in, and this morning, again it stuck on me.

 

What happens is I get about 2 miles away from my house and the gauge slowly climbs past half, till almost in the red. Then Snap, it'll open up and the temp will drop to normal and stay fine till it's starts cold again.

 

Also, this morning a hose sprung a leak. It's the small hose that goes from the thermostat housing (or there-abouts) to the intake, just below the carb.

 

So, I'm not sure if the hose thing is related, easy fix though which I'll have to do at lunch...

make sure the coolant is full and no air in the system.

 

could the radiator be plugged?

Have you replaced the rad cap? It may be popping off at too high a pressure... that could explain the busted hose.

 

Just a thought...

Cap was replaced when the 1st tstat was changed, so yeah, it's new. Radiator is semi new too (replaced by the guy before me).
