Auxiliary Engine Cooler?

[redoil]

I haven't posted for a while. just took a trip towing a 7000 pound travel trailer with my 2000 Excursion 7.3 psd. had some problems overheating (engine) through the NC mountains. Can I add an auxiliary radiator with a fan on this truck -- or a larger radiator?

You can but where you going to put it. I don't think there is a bigger radiator unless your gonna go with one from a Semi truck.

I would find out why your truck was overheating. Was the fan clutch engaging properly, is your radiator clogged, are the fins blocked with dirt and debri so air can not flow through it. I mean there are several reasons why your truck would over heat.

If everything is working good you could try adding water wet'r or some other additives. That would be a cheap place to start. I know we stock and sell alot of the DEI products. Do you work in a high dust area? I know with my semi trucks a good power washing of the RAD helps alot. We work in some high dust areas. Thats two cheap things to try is everything appears to be working.

ok -- i'll clean up the radiator -- i was driving with my foot all the way to the floor up a mountain with both front and rear AC going -- for about a mile and the temp gauge got near the red zone. so maybe I should expect trouble.

The cooling system on the 7.3 is so over designed you can remove the fan and rarely have heat issues. I would say you might have a fan clutch issue or your just being overly cautious. I have never had a heat issue with any of my 7.3's...

I ran hot once....had max A/C running with out side temps around 109 switched to reg A/C kept it around 60mph & temps went back to norm. This was the only time. Don't know how much more max a/c works the engine

WOW! I figured with this huge radiator and fan it would hold well. Actually, I pulled a 8k trailer up the pass at around 60 mph and the engine did not get hot. The ETS were getting dangerously close but she held flawlessly! AC was on full tilt as well! I agree with the others, I would find out why it was heating up. I recently replaced my water pump and thermostat. The pump was dripping slightly, and the thermostat was defnitely in need of replacement with only 120k on her.
