Hey all, looking for some input and advice here on my 2006 long-tall 2500 (265k) van.
The engine has been running pretty consistently at 215F when driving on flat freeways at 65-80mph. Climbing a hill or mountain pass in the Summer it can get up to 230F, and then I turn on the heat, roll down the windows, which can bring it down to 215F if I down shift to 3rd or even 2nd gear. Going down the mountain it cools down to 180 no problem.
The radiator was replaced (it was actually stolen...long story) at around 150-160k. The coolant has been exchanged several times since then, due to repairs, replacement of head, replacement of harmonic balancer. So, the coolant isn't old.
Are these temps abnormal for flat freeway driving at ambient temps of 80F+...?
Any advice on how to clean, service, etc to get this puppy to operate a bit cooler?
EDIT: also, the aux fan comes on when it's supposed to (as far as I can tell, I hear it). And I've have the big/main fan replaced this Feb. It was running all the time, so it may have been over cooling...? Still confused....
