Fan hit the radiator again
Tonight I heard a strange noise so I opened the hood and found the fan hit the radiator again. It doesn't seem to have damaged it other than it tore off the thin support straps that go from top to bottom and scrapped some of the cores but it is not leaking. I replaced the motor mounts and the trans mount also and am still having this trouble. What else can cause this? The rad came with new mounts and all so they are not worn. The fan is a good used unit that I bought from a friend that was never hit or bent. How much clearance is there supposed to be between the fan and the radiator?

Is it a thicker core radiator, you should be able to get your hand between the clutch and core.
Is the fan bearing loose, there is a bolt on the back side, the fan has a tremendous amount of pulling force especially inside a shroud, I have seen fans suck themselves into a radiator if they hit water or the core gets swamped.
Is the hub hitting or the blades?

The difference is ~ 1".
For the STEEL brackets, the holes for the isolator are offset FORWARD on BOTH sides. The bracket with the half-moon notch (which faces UP) is the driver's side bracket.
The cast blocks that the steel brackets bolt to are offset by 1/2 inch FORWARD, meaning the cast block has a 1/2" bias towards the REAR.

Double-check that your mounts are correctly installed, sounds like the WHOLE ASSEMBLIES may be flipped side to side.

When the fan hut last time it made a full circle. This time it seemed to only hit on the driver side about half way up. I see my problem now though. The stamped steel brackets are swapped from side to side. The bracket with the slot you have pictured on the passenger side and mine is on the driver side. And the one with the round hole is on the passenger side. Looks like that hole is off set to the front when properly installed and mine are reversed. Thanks a lot for the help you guys are the best.

Ok I was wrong the driver side frame is slotted but the mount bracket is not. My brackets are just like they are in the pictures. If my radiator support was back that far I would have alignment problems with the sheet metal and I do not. What else could cause this? The fan is so close that when I thread it off of the support hub that it hits the rad a little on the last couple threads.
