I drove south through the San Joachin Valley in Sept. Outside temp was 105*. With my camper on the truck coolant temp never exceeded 190*. I climbed the Grapevine,a steep section of I-5 north of LA and same deal. No problem. I didn't have one on my '98.5 either.How is the engine coolant temperature, when ambient temperature is really warm?
I'm going to venture a guess that the picture in avatar has somethign to do with that... :hehe:I have been wanting to replace mine too. I just think the front ends looks funny without them. I have talked to a few people about used ones, but cant bring myself to spend what they want for it, especially since it will probably just get ripped off again.
