Electric Fan
undefined[[/FONT]undefined 
Installed a 16" Electric puller fan with a 185 hypertach fan switch installed in the intake, with a relay. Fan works, but temp gauge got dangerously close to the red. Never did that before with the mechanical fan. Also the engine started cutting out, I wonder if the engine was getting too hot. I checked the overflow bottle and it was still in the full cold side, even with the engine reading 220. Any suggestions appreciated. I like the electric fan, but may have to go back to the mechanical one.

Does the temp go down when you are moving (say at 50mph or so) for a few miles? If not, then it's not your fan. Maybe there are some air pockets in the system if you changed or did something with the coolant.
I'm running a similar sized fan and don't have problems.

Realized that the inline fuse I had installed may have hampered the fan output. I had a 25 amp fuse, went too a 5 & 10 amp and it blew. The 15 amp worked good I could tell the fan pulling more. I then clipped the inline fuse out and will try it. I also have a new radiator. I cann't afford the aluminum one. Thank You for all your replies and suggestions. I love this column.
