Anyone running an electric cooling fan with a thermoswitch? If so, where did you locate the switch?

Some rad have a bung in lower tank for it,if not some switchs fit the drain on lower tank,if not on hotrods you could put it in were lower heater hose would go if no heater. There is some ideas.

Hi! I drilled and tapped (pipe thread) into the intake manifold behind the thermostat. The control box I have has an adjustable pot and is set to come on at 190 degrees. My 292 wont overheat even without a shroud and stock 1956 rad. Love it and no drag on motor makes it snappier.

Scott;

Wonder if you could use a "T" fitting from the heater hose port on the intake behind the T-Stat housing??

I used an an existing hole behind the thermostat housing. I don't know why you couldn't use a T for it. Its not rocket science since the on/off for the fan isn't that critical. The T would get plenty hot. They also make a sensor that fits into the radiator hose at either end. Chuck

Might be a neverending battle which is better, upper or lower radiator hose, but I prefer upper.

I check the temps at the upper and lower hose all the time with one of those temp guns because of my "fear" of the always moving temp gauge on the dash. Normally I've found the the upper 35-40 degrees hotter than the bottom. It's a new max cool radiator. I would not put anything in the bottom unless it was controllable after you check the differential temps.

The gauge has settled down since I followed a suggestion from Greenbird by plugging the bypass and drilling a 1/8" hole in it......Good Luck

Perhaps an adapter for a temp gauge in the passenger side head, that's what I did for my mechanical gauge so I could still use the factory dash gauge. They replace the rear freeze plug in the head and are available from a variety of Thunderbird suppliers and probably others.

The top rad hose should always be hotter than the bottom. Water rises in the motor falls in the rad. So After the rad does its job should be cooler coming out. This is why I put my fan sensor right before the thermostat myself.
