So I recently figured out I hsd s bad fan clutch and seized electric fan. I replaced the fan and clutch with what appeared to be a good one out of a 2001 D2 and also installed a new electric fan. Truck idles at 188 and also stays around there in traffic but once I get up to 70 it goes right up to 210. I'm driving with 2 kayaks on the roof but that shouldn't be an issue. Everything in the syst is fairly new.

 

How old is the radiator?

 

210 is not out of line, yes it might be improved on a little depending on your ambient temp. Also, a new clutch would most likely benefit you over a somewhat we'll used one.

 

The radiator is a couple years old and was flushed last year when I fid the head gaskets. I also installed a new water pump with a bronze impeller and a genuine 180 t stay at the same time. Regarding the fan clutch, I didn't think the fan did anything at 70 mph.
