Water jets for radiator / oil / trans coolers
I just found another interesting upgrade/change on my "new to me" 1997 MH. I found 4 jets that point at the radiator and the engine oil and trans coolers. It looked like a water line was run to a co...

Those of you that have installed this system do you put it at the top across the A/C heat exchanger or in between the A/C across the actual radiator itself? It looks like it would be an easier install in front of the A/C heat exchanger.
Gjac,
When I did mine, it was on a '77 Four Star, Class C Dodge. I set it up so the tubing I built, was about an inch away from the top tank of a vertical flow radiator. When I triggered the pump, the little holes I put in that tubing, sprayed directly at the top tank. That way, to me, it "pre cooled" the water as it entered the radiator from a hot engine. Then, it would have time to continue cooling as it flowed down it's normal path and into the bottom tank. And, like I stated, I removed the presence of the auto trans cooling in the bottom tank. That way, the cooled water/coolant, was not "pre warmed" again by the hot transmission fluid, prior to it entering the engine.
Now, on this Diesel pusher of ours, If I were to do it on it, I'd have to plan some interesting routing, because it's a horizontal flow radiator. And, in case you, or anyone else has not done any radiator work, that radiator, on a rear radiator unit, (not side cooler) is seriously tight in there and it would be darned near impossible to put it so it's aimed directly at the entrance tank of it. I'd have to come up with plan B.

Directing the spray across the radiator core should work fine. The air flow would pull the water spray through the core and across the fins which is where the majority of the heat exchange occurs.
