Internal viscous coupling is a bit different. You *CAN* use the gasser fan clutch, but you'll lose some cooling.

 

I know I've read about guys who just ditch the fan all together. So is it a safe bet that the gasser clutch would buy me some time until I can get the propper part in there. I drive mostly unloaded on the highway, but I do see ocasional traffic jams where I'm driving 5-6 miles at 20 mph. Thats why I'd like to have some sort of a fan.

My fan wobbles pretty bad on the end of the shaft there, and I'm afraid of throwing the fan through the rad if it gets much worse.

 

Just pull the fan now. The wobble of unbalanced weight is killing the bearing in the water pump. But, the radiator is easier to replace than the water pump you are tearing up. :doh:



I've had my truck at idle for about 20 min without a fan. Just don't run the a/c. The cooling system can take it, but monitor your oil temps. If your oil hits 230*, change it. Oil temp is gauge ford SHOULD have put in.

 

Well, I pulled it on friday evening. Everything has been fine. I will get a new clutch put in it soon. I have to get the fence put up for the wife first. Thanks for the help!
