Thanks, Its and RV trick to add a Temperature Gage to compensate the Hot Idiot Light on the dash, also know a few guys that have used the same Ideal on the Transmission oil cooling line but used a 3/4 in. copper tee with the bulb in the tee so it did not restrict the flow. they didn't won't to drop the pan and have some one weld a threaded bulb for the sensor. By the way thanks for not pointing my sailing problem........... My wife says my RV looks like an airplane with all the temperature, oil, and battery gauges.

I hadn't thought of Copper tube. I may be able to find a piece here at work as there was some large pieces left after the last renovation. I think I may try mounting a wet sensor in the return hose. As long as I keep it down around or below the 210 degree range it should be fine. So I'm thinking that if I pick up one of the G.M aftermarket wet sensors that trip at 195-200 range they will kick on when the returning coolant gets to the point that it needs the fan on. I know 87-90 XJ's had the sensor in the radiator tank close to the return hose, IIRC! If I had thought of it I would have had a bung added to the lower radiator tank, but it is in and mounted and I fooled with it all last weekend to get it how it needed to be with the G.M electric fan on in. I'm not pulling it out again!
