Engine Temp

The fan position is about inch forward in the fan shroud.
I feel pretty sure the temp gauge is pretty accurate.
I have not checked it with a manual temp gauge I guess I could.
If I let it idle for a long time in the heat without the a/c running it will get hot enough to bring out coolant I only let it do that once.
Couldn"t get out the traffic to pull over was in a bad place.
I guess I will try a fan clutch and a regular fan as you suggested before I put an electric fan on.

Thanks for everyones suggestions any more?

Sonny K.

I have a 390 that was bored 0.020 and seemed to run hot also. There was the Ford gauge and then an aftermarket. In the end I put a thermometer the radiator to see what it said vs. the two gauges. So in the driveway it ran right at 195-200 with the 195 thermostat. The Ford gauge needle was straight up. The aftermarket gauge was at 225 degrees. Obviously there is an issue with that VDO gauge. The truck has a shroud, with a 7 blade fan,spaced the correct distance inside the shroud.

If you decide to go with an electric fan, a low dollar choice would be a fan from a '92-'93 Crown Vic. Those fans are inside the shroud in front of the belt driven clutch fan. I use one of those to cool my Ranchero with a/c and it works perfectly. If you can find one in a Pick your Part yard you can get them for about $35. and they move a lot of air. I run mine with a switch that you stick through the fins by the upper hose through a relay. It also runs when the a/c cycles. I power my fan with a 30 amp circuit breaker feeding the relay, zero problems. Good luck!

I've never overheated and dumped coolant but here in TX on 100 degree days and heavy traffic I approach the upper line in the stock gage and it can be a little stress producing. I'd like to add a AutoMeter temp gage to see what the actual temp is running as a reference to what the stock gage is reading. Has anybody run 2 gages off the stock water sending unit? Like to see if I really have to fret.

TIA

You can always buy a temp gun to verify your actual running temps including block temp, radiator temp etc.. They run around twenty to thirty bucks and would provide a good reference compared to your gauges.

Your stock gauge uses a different ohm range and voltage than the Autometer. The Autometer would require it's own sender and power supply. All the stock gauges are going to read a little different depending on the ICVR and the gauge. I checked my gauge out of the truck with an accurate thermometer and the the top of the normal range was 195 degrees.
