85' E350 460 Engine Coolant sensor resistance
Hey Guys/Gals, new to the forum. Wondering if someone can help me out.
The temp gage on my E350 reads low even after its at operating temp. It does come up off full cold, but not much. Am trying to find what the resistance of the temp bulb should be cold vs hot. I get 370 ohms cold and 55 ohms hot. Was wondering if the 55 reading is a little high and not driving the temp gage needle to mid band where it should be, but the Chiltons book I just bought for it doesn't have anything on it. Its got the 460 carberated engine and the 1 terminal screw-in temp sensor at the front of the intake. I know the sensor is proble $10-15, but I like to verify the parts actually bad before I start swapping out parts. Also, is there a better maint book I can buy for this rig other than the 1961-1988 all encompassing Chiltons E-sereies book I have now? It doesn't have much in the way of wiring at all. Its actually a Jayco Mini RV on the Ford chassis.
Thanks, Jamie

I've had to replace that little sender a couple of times on my '82 RV in the past 10 years. I've got the Chiltons too, and it's not the best, but it's all I got.
Keep posting your questions, and the guys here seem to be able to come up with a diagram. Whenever one of them gets pasted in that's even close to my model year, I save them, print them, and stick them in my Chiltons.
