Won't warm up?
 

I need advice on getting my pickup to get up to operating temp. I recently put a new radiator, thermostat, and water pump after I was in a wreck had to replace the radiator and the thermostat was sticking so I replaced it and I did the water pump because it was easy with the front end off. Anyways after all that it won't warm up past the first line and it used to go to the middle. This is not a problem now since its summer time but come winter it will really suck!

Cummins thermostat? Or an autoparts supplier special? Stant, napa, etc thermostats fail constantly. A cummins replacement is your best option.

x2 on stat.

I put whatever brand orieley has in it I didn't realize that it would make a difference I couldn't justify paying 50 bucks for a little thermostat but I guess it woulda payed off. I'll try that and see if it fixes my problem thanks guys :c:
