The pusher fans installed are not cooling enough in 50 deg. weather. I have a 185 thermostat and it is working. The engine is a fresh rebuild, and has only run about 2 hours. I have a new aluminum radiator from Champion, made for the straight six, however, there are tranny oil cooler ports at the bottom, that makes me thinks it is a universal (6 or 8). The radiator is installed at the back or the radiator support, and there doesn't seem to be a more forward set location available. How can I possibly install a fan and clutch, for a 235 engine that has been installed in the original mount location?

Are you driving down the road and getting hot or sitting still and having cooling problems? | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | A fresh rebuild will have more friction and tend to run hotter.
Make sure you have it timing advanced enough.
When you say short shaft I assume you mean a modified long shaft pump. They can work OK but are not the best for cooling.

They can work OK but are not the best for cooling. I'll second that. I ran a short pump in my 1 ton for years and it was just marginally OK at cooling. Had I known then about the water pump adapter plate I would have used one then and recommend that you use one now. Grigg | | |
