Taking the engine cover off as suggested above is a start, however an additional inch or so of clearance is required. I have heard many people say that getting access is very difficult, and this is my experience. The objects which block access are massive and have a lot of wires and hoses attached to them.

I have seen posts in which people seriously suggest that dropping the engine a couple of inches for access by undoing the bolts on the engine sub frame is the best way to get access to this fan. This is pretty extreme, and I will try this last.

I have seen a post suggesting that taking the intake manifold off. On a 330 this is a serious job. I have a feeling that on a 325i it may not be quite as bad, but still to R&R the intake manifold on these cars is not a romp in the park.

I will probably remove the intake manifold next, in order to create clearance to install the fan. I have just ordered the gaskets, and I will be looking for limited service items, like hoses, to replace while I am in there. If any one has replaced a blower lately, I would be very interested to hear from them, as to exactly which parts need to come out in order to replace the fan.

Thanks in advance for any help.

Okay. I am a Newby and I missed the many interesting suggestions written AFTER the early post which I referenced. Apparently removing some of the windshield wiper structure will help. Lots to read here.
