I started to tow with my 95 F150 5.0 Air/Auto. I'm trying to control the temp going up extreme hills. I have what I believe is a two row radiator now(original). I also have the original water pump. There is 110k on the clock so I'm thinking changing out the water pump, but is there an upgrade to the radiator I can do?

What do you guys suggest?

 

A few here have switched to electric fans, if you search the forum for the postings, they provide links, info, etc, etc. Some say it's a good improvement, less rotating mass, less strain and whatnot. There's a fairly affordable set up available on eBay, although some prefer to buy the parts and build their own. That's the only thing I can think of othere than if you're missing your fan shroud.
Supposedly it also gives you a few more MPG as well. Hopefully someone better informed than I am will chime in????

 

you can put some water wetter in the radiator which will bring the coolant temp down.

 

There's no point in changing the water pump unless it's leaking. It will pump just as well as a new one. You can get a four row radiator.
