The radiator fan for my 98 12V 5 speed 2wd is no longer available from Chrysler. It has developed a few small cracks. Would like to replace before it becomes a major problem. Who is a good source?
I'd look for a used one on eBay, there are a couple of vendors that part out these trucks and sell lots of parts. They don't sell junk and will back up their used parts too. The Horton is a nice set up but it's a few hundred bucks, you should be able to get a used replacement for about $60.
For now, if you are driving on the highway and not towing too heavy (near max GCVW), you can run without a fan. I've done it for a few summers and the only time I had a problem was in bumper to bumper in Chicago after about 20 minutes.
