Fluidyne Radiator for Automatics - ZR-1 Net Registry Forums

After a delay, I'm working on the radiator again. When I dropped in the first radiator that I got, the inlet pipe on the driver's side was almost against the fan shroud. I took a picture to the shop that got the radiator for me and they emailed it to Fluidyne. Fluidyne sent a new radiator, this time for manual transmission and there is more clearace.

The advice on cutting the shroud and removing the thermostat housing was a big help. It also helps to follow all the instructions in the service manual. Putting a little silicone grease on the rubber top mounts also helps.

Right now I''m having a problem on the driver's side. I think it's because the mounting tabs on the top of the radiator are a little over 1/8" farther apart than the stock radiator mounting tabs. I may trim the rubber to fit if I don't find any other hang ups. Getting the inlet hose on is also going to be a problem. The pipe looks like it's the same size as the stock radiator but they flared the end a little. I don't know why they did that. There is a little bulge just before the end of the pipe that should give a tight fit. If I can't get the hose on, I may have to cut a little of the flare off or bend it in a little.

By the way, using gloves to protect your hands really helps. I couldn't find mechanic's gloves that were small enough so I got golfing gloves.
