when i let my truck(03 cummins) idle it gets up to like 140 on the temp guage and thats it. should it get up to normal temp or is it some kinda safety or something that it will only get up normal temp when u drive??

thanks guys

 

Mine won't get up to temp at idle in the winter either. I beleive it is because the engine gives off as much heat as it creates.

 

ittl get up to temp once u start driving tho right jakebrake?

 

It'll run 190 when I drive it, even after driving it, if I let it idle for about 10 to 15 min it'll drop back down to around 140-150.

 

mine doenst get up to temp until about 7 miles from home... if i fire it up, it'll take forever...

 

With all of the homes that you have Steve, I don't think there's more than 7 miles between them all.

 

alright cool. thanks guys. i thought i was gunna be replacing crap already. but its good to know that this is normal

 

On a side note, you don't want to let it idle cool like that for too long. It is not good for these engines. Run it up to temp once you start it in cold weather.

 

I'm down to 3 (sold one) and your right... the farthest is 6 miles from home
