Thermostat Question
I have a question about the thermostat on these engines. I drive to work and around town.. the temp is always in the middle but the lower radiator hose is always cold to the touch even after a run? Does it take a lot of hard driving to get these up to temp?

With a thermostat that didn't open, I could operate freely at less than one third throttle and not overheat.

More than many other diesels, certainly much more than a gasser.
Describe your driving mode, and ambient temps. Is the radiator as cold as the lower (return) hose? Is the rad temp consistent top to bottom, side to side?

I drive about 15 miles to work one way. I do drive easy for best mileage and the temps here are pretty cold right now. I would say 30 to maybe a high of 45 F

If I just start up an leave, I'm up to operating temp by the time I reach the highway 2.5 miles away.

Same here, In my case it`s appr 2miles usually taking 5-8mins driving, depending on traffic but very light driving, several redlights, Winter cond.
Idk if it makes a diff but heat/blower is definitely off (it`s often 14-20F (-5,-10C) now in the mornings) * ``the temp is always in the middle but the lower radiator hose is always cold to the touch`` My lower hose is always somewhat (or more) `colder` than the upper one, even after driving an hour at 65mph. A digital (non-contact) thermometer is your friend there Last edited by RedArrow; 01-15-2014 at 05:25 PM. |

Hot water in on the top and cold out the bottom. I assume that is the coolant
Flow. I would say the radiator is just getting the coolant close to ambient Tempature If a t-stat is stuck open the motor usually won't warm up at all do to the coolant Always flowing |
