Ihave an 82' 300. Almost done witha full resto, but i have heard that I should put some electric fans into it b/c it frees up alot more air for more hp. Also i still can't find where the water temp guage wire goes. I alos have to find it coming out of the fire wall. Does anyone know what is the best thing to do and where it goes?

 

Water Temp sensor is UNDER the intake runner for Cylinder #6. It has one wire going to it. then trace it back.

 

Electrical fan can increase power if ambient temp. is cold or almost freesh, because once engine tempe is going over 185ºF it will need cooling, son electrical fan start but it use power coming from alternator and it use power from belt, same used to move water pump so power comes from same place >>>engine crankshaft

There are differences, because fan clutch has low reponce so it can still blowing when engine is actually fresh, electrical fan stop as soon as temperature goes down.

There are some electronic controller able to control even fan speed, the blow just enought air as needed by engine, this is real power saving and maximun efficience.
