Beyond stumped on this.

IAT2 is through the roof. Cruising temps hover 130-140. Car off the IC pump is DEFINITELY flowing they shoot up to 160 and sit there.

The pump works, i hear it and can feel the coolant running through. I squeeze hose from filler neck to H/E and the neck pisses itself. Feel hoses in and out the endplate and feel it flowing. I SEE the coolant flowing. So what the monkey **** is going on? The pump works no doubt about it.

 

mods?

 

thermostat might be stuck open. my temps would hover around 150-160 and it turned out that a gasket had broke and jammed its way into the thermostat. might wonna check that out. as far as the intercooler goes....i cant help you there.

 

Stage 2 pulley, 60's. Intake header ZZP H/E. Stock one is MIA.

Irrelevant, im talking strictly IC here. Thanks for input though

 

stock endplate?

 

Yes.

 

hmm, cause im running gm stage 2, and only cooling mod i did was option b and was running 120-140 then put my stock ic tank back in and now im at 90s.

 

Air in the system?

Sorry, that's always my suggestion for threads about this problem.

 

oh **** my bad. i mis read the post

 

So I went and looked more at the pump. It shuts off and comes on as it wants to, and yesterday I found it completely dead. Hit it with a hammer and it kicked back up. It was running last night last I checked, but IAT's are still sky high. I think the pumps shot so I'll be doing a new bump+all water for the summer.
