blazer overheating

greenblazer02 · 02-07-2010, 10:49 AM

i am having a problem with my blazer. i just got back from a deployment and now its overheating. the crazy thing is that it seems to be heating up while i drive but when i stop it cools down. alittle backwards right. i have a 180 thermostat that i installed about 2 or 3 years ago. it also doesnt have heat anymore. could that be the thermostat having gone bad? im thinking that it is. im a little nervous that it could be the water pump. what do yall think?

what does your rad look like when you take the cap off?

i had the same problem last summer. turns out the dexacool crap had clogged my system. had to replace rad and flush system

I'd say radiator flush too or the hose is colapsing

thanks for the advice fellas. it ended up just needing a new thermostat. works like a champ now

Well I'll be damn, thats crazy,you would think it would overheat all the time with a bad thermostat...

not if the thermostat is stuck open. it can allow the coolant to pass to fast thru the rad and not cool while driving

Well with it open more than likely it WONT overheat.

It had to be a thermostat problem mixed with low antifreeze. ANY time you don't have heat, it's because you're low on Antifreeze, or theres a bubble you need to burp out of the system, and fill it again.. but yeah man, good to hear you got that taken care of... Hope you did it yourself, save some money.
