its been really cold here past few days about -22 F without the windchill -40F with the wind chill. my truck has been plugged in and i went to go out today and i my truck ran and drove for about 10 minutes and my temp gage was reading just about half way which it has never done before and my truck wasnt blowing any hot air is this just something as simple as my thermostat being stuck or do i have bigger problems ? all of my lines were warm and it didnt appear that there was any ice in my over flow tank so im realy hoping something didnt freeze up in one of the lines. any help would be greatly appreciated thanks guys

 

but, if your thermostat was stuck, it would be stuck closed, and your truck would overheat pretty quickly. it might be low on coolant. if there is not enough coolant, and it would be really low at this point, your heater would not blow hot air. so i know how it sounds, but check your antifreeze level, if thats not it, i dont know.

 

well it did seem to be over heating pretty quickly my truck only ran for 10 min max and it is -40 here right now if not colder and in the 10 min the temp gage went above half before i turned the truck off

 

Not good. Heating to fast and no heat from heater means your coolant is freezing... Get it in a garage before something really bad happens. Then flush and get some better coolant in it.

 

Sounds to me like your coolant is shot or the ratio of water to coolant is way off, too much of the H2O...

 

its pre mixed stuff good to -40 celsuis so i doubt thats the problem

 

ok so my coolant was a tad low i topped it up and it doesnt seem to be over heating now had it running for 10 min again keepingh the rpm's around 2000 and the temp gage just stayed a bit below half which is where it usually is but still no heat

 

well whateevr it was its fixed now a sat the blower drier on the thermostat for a good hour added some -60 antifreeze and i dunno what exactly did it maybe a bit of both but its working now so thank you for your input
