RE: 2001 Dodge Truck Overheating
how hot are we talking about here ? about 195 is normal. AC adds another 10*. slow,stop/go can add another 10* easy.
you could replace the stock 195 w/ a 180*, which should yield some improvement. if not enough improvement you could then try a 160*, but that one's more likely to throw a code and set off the check engine light, however, that won't hurt anything. i would do this first.
you could replace the fan clutch. might help, might not.
you could add a big ol external transmission cooler. this might help because your radiator also contains a transmission cooler, so there's a lot of heat trying to dissipate there. a/c adds a lot of heat too. i'd do this too, as it will make your trans last longer.
you could replace your clutch fan with electric fans, set to come on at 170-180*.
