Reply to "Radiator & front condenser clearance"

A Fluidyne with shrouded sucker fans AND a front-mount A/C condenser CAN be installed with the rad in stock upright position but as you've found, its not easy. There are three minor mods most of us do to fit big radiators and/or front mount A/C condensers.
First, cut the few spot welds that hold the pusher fan mounts and remove the entire assembly. Shrouded sucker fans are far more efficient, will lower your running water temp and are simpler to install.
After that's done, add a pair of 3" long straps between the radiator top mounts and the radiator body mounts such that the rad tilts foward at a 20-40 degree angle (exact angle unimportant). The lower mount posts welded on the radiator will pivot in the stock rubber bushings and the welded frame brackets.
This is done strictly for convenience in servicing and installation; the lay-forward position will have no effect- positive or negative- on your engine water temp.
The last thing you need do is make a new upper sheet metal panel to fit the far smaller opening now between the front edge of the rad and the body, so all the air coming in the grille goes thru the rad, not up and around it. Not doing this will raise water temps by a significant amount. A simple flat sheet metal panel held with a few sheet metal screws will suffice.
NEVER use plastic tie-wraps to hold the shroud to the Fluidyne rad. The tie-wraps will eventually cause water leaks & ruin your radiator.
