truck wont warm up
My 1994 v6 gmc 1500 4x4 will not warm up the
gauge barley gets over 100 an it blows cold air i
replaced both coolant sensors an put a new
thermostat in an i even took the fan off to see if it
would get warm an it wont i have tried everything..
thanks for the help in advance
verify the temperature before and after the thermostat - it is possible the gauge is faulty
I just drove it like 4 miles i wanna say an i can get out an grab ahold of all the hoses on the motor
An the truck didnt barely move from 100 when i change the thermostat
if the coolant is full and the temperature is still low then its possible the new tstat is bad - that is the only temp controlling component I the system.
But with no fan it would still get hot shouldn't it
if you have acces to an inferred thermometer check tsat housing temp and make sure the housing gets to operating temperature
without a fan or with a fan if the tstat is stuck open it will not heat up properly

I could touch the manifolds even though
The exhaust an i tested the tstat an i touched the intake
Do yo have access to a inferred thermometer (electric laser thermometer) you need to physically check the operating temperature of the vehicle - make sure it is warmed up properly - I'm not sure where you live, I live in Arizona so it only takes about 5-8 minutes to warm up a vehicle to operating temperature
I agree with MStamps, gotta be a defective tstat. Take it out and put it in a pan of water on the stove with a thermometer, see when it opens. It may be open now when you pull it.
