hey,

i just installed a 160 degree powerstat from hypertech. once installed, i used the hypertech power programmer to set the fan kick-on at 185 degrees. the problem is that the temperature gauge is telling me my temp is 270 degrees and my check gauge light is on. why would i be overheating with a 160 thermostat and fans running at optimal times and what can i do to fix the problem? THANKS!!!!

Is the thermostat opening? If it is then I would try to flush out the system, if that doesn't work it might be time to start looking at a new water pump.

ok ill definatley try that. you know how much an electric water pump is gonna run me? thanks!!

 

could it possibly be that my temp gauge isnt right, it says i was running at 265 degrees and the surge caps wasnt feeling super hot and i didnt hear anything boiling. any ideas?? thanks!!

 

Do the fans run on high all the time when the gauge reads hot?
(ECT sensor telling pcm it's feaking hot down here)
Might try replacing the ECT sensor.

 

Did you properly bleed the coolant system after installing the thermostat? You might have an air bubble in the system.

 

i went out and bled the coolant system this morning and there were a lot of bubbles!! but once i finished that, the temperature was perfect...right around 190 degrees. thanks for all your help!!

One thing I've gotten in the habit of doing, is
drilling a small hole in the thermostat disc when
I swap in a new 'stat. This lets bubbles pass and
ensures that when closed, the 'stat "sees" the
true coolant temp (not totally stagnant water).
Just one little 3/32" hole won't hurt nuthin'.

 

That's all just weird to me. I've drained my system several times-never had any problems. Never had any "air pockets" in any vehicle I've ever done a coolant change in, either. Maybe I'm just lucky, or I know what I'm doing.
Glad you got it fixed, though!

 

thanks.
