Are you running the ranger heater core and radiator?

Even though it's opening a little at 80, I'd replace it anyhow. They are only a couple dollars, and it's good peace of mind.

Maybe the radiator and the fan flows enough that the engine isn't under enough of a load to get the engine warm. I would try putting cardboard or a feed sack in front of the radiator and see how it works then.

11-01-2013, 07:08 AM #5some time ago when the truck had no ac i was using a 14 inch fan,one day i noticed that the fan wasn't working but the engine was at the right temp,but i was away from home so i drove home no trouble,but then i was so busy that i forgot that the fan wasn't working,i run that truck for months without a fan,fast speeds ,congestions any condition the motor doesn't overheat,then i got a big and powerful BMW 2 speed electric fan ,installed the ac and a fan switch set up at 190,low speed for the engine cooling high speed for the ac,the fan never kicks in with the ac off and i tested the switch,it took like 45 minutes idling to get the fan running for like a minute only
