I work with a guy who has a 98 F-1, 4.6/auto 2wd with about 210,000 on it.
Truck is in good shape and has never been abused heavily. Problem is, he's on his 6th radiator, and he's not sure why, and the mechanics he has used have not been able to penpoint the problem. I dont have any detailed info, Ill ask him tomorrow at work, but what are some possible causes to this? He said that one mechanic commented on some electrical problem...any possible connection? Could it be the brand of radiator; as far as I know, he's used factory replacements.

Thanks guys!!
