cooling problem from hell, part duex!

gp001 · 03-11-2001, 11:56 PM

I have had 3 bad experiences with Stant thermostats in the past 2 years. 1 when I built my 347, damn thing would stick intermittently. 1 on my Dodge truck when I did a head change. And 1 on my buddies vette when we did a cam & head swap. The last one scared the @#!% out of us because when we fired it up to break in the cam the temps went through the roof. The only way we knew it was the thermostat in all 3 instances is because we have a Gano filter installed in the rad hose and we could see through the clear tube that little or no water flow was taking place.
Also, make sure you have no air pockets in the system. Check your fan as described in another post, and you might want to try running it without a thermostat to verify you are getting good flow. Boil the thermostat to verify it is working
