Van, you never cease to amaze me.

Just a side question. Do you have the rear radiator or side?

And you never cease to amaze me at solving 12 VDC problems, Myron!

My coach is a 2000 Dynasty 36 with a side radiator. Its RADIATOR fan is controlled by a purely mechanical wax-type controller. I mounted a SEPARATE radiator and electric fan controlled by a thermostat for the transmission cooler so that coolant and transmission fluid could never mix. The engine has always run relatively cool, never exceeding 195*F even under extreme conditions. The separate trans cooler was just "insurance" before setting out on a trip to Alaska four years ago. At that time there were quite a few posts about in-radiator transmission coolers rupturing and destroying transmissions. My setup has functioned for four years without a hiccup.

Thanks for the reply. Just going to add that on my rear radiator setup as you know but not everyone does is that there is a fan blade available that instantly takes a huge load off the engine. I measured the acceleration before and after and just using a crude stop watch test but and the fuel mileage increased as well.

Cheers.

Myron, I've often wondered how much unnecessary power is robbed by the highly-powered hydraulic fan on my coach. Someday I may see what I can do to remotely manage the fan's hydraulic motor. It would be interesting to watch coolant temperature as I remotely controlled the fan speed.

Oh well...another entry in the "Project List"!

If memory serves me, about 35 hp for the stock rear radiator fan.
