    Fan Shroud Alignment problem

    I bought a 325e last summer, and it came without a fan shroud. Since I'm in TX, I decided I'd put one back on.

    I bought the correct shroud according to realoem.com, and was trying to install it as a final piece of replacing the water pump and timing belt. When mounting the shroud on the radiator. the center of the opening in the shroud looks to be offset an inch or so to left when looking from the front of the car relative to the center of the fan, and there's no clearance between the right side of the fan and the opening in the shroud. The radiator is sitting correctly in the rubber mounts, the radiator mounting bolts are in the correct holes in the radiator support and the tabs on the bottom of the shroud are in the slots at the bottom of the radiator.

    Has anyone else had this issue and if so, how did you resolve it?

    Thank you in advance for sharing your experience.

    Hopefully the car was not involved in a front collision

    The front 4" or so of the driver's side fender has a dent in it, but that doesn't seem to be enough to account for that kind of shift in the radiator support. If there were, I'd expect the hood to be extremely misaligned, but it's not.

    I would not expect left/right alignment issues that severe with bad motor mounts. I would expect up/down issues. Take a good look at both frame rails. Compare with a "known good" E30 if you don't see anything obvious. Something is bent somewhere.

    Or you could have an aftermarket radiator that didnít have the fan shroud mounting points put in the right location

    This is very likely, i have an INA radiator and it is just 1-2 mm off on the shroud mounting points. When i laid the old radiator (origina 30 year old BMW one) on top of the new one, everything lines up (to the naked eye). Only when i mounted the shroud i noticed it was just that smidge off, just enough to make one notice but not enough to cause any issues, some slight hand pressure was enough to get spot on alignment.

    Or maybe the plastic parts on the old radiator have expanded and contracted so many times over the years, the alignment slightly changed when compared to a brand new one?

    Or were there different sized shrouds available?
