blazer not gettin up to temp
my 2000 blazer is not getting up to temp , i flushed the dexcrap out and put in the green antifreeze, i back flushed the heater core and everything else seems to be flowing , could it be a bad t-stat, or water pump.

I would start by checking your thermostat, they are designed to fail in the "open" state, so if it is bad it will let coolant constantly flow. The other thing to try is hook up a code reader and check your temp. that way, possible the gauge is reading right. and do you have heat coming out after 10 minutes or so of running?

Got my thermostat for $6 and tax, replaced it, and the truck gets right up to temperature now. Thanks guys, heat is like 3x as hot now. I lost about a quart of coolant, so plan for that as well. The install was very easy, just have to make room for the T-stat pipe to pull out of the way.
