Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Leading evidence: 'Use nuts and bolts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use nuts and bolts' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Guys, I’m wanting to remove the fan and on my new 3.2 and clean it up. Being such a dominant part of the engine bay visually, I thought it’d be a good little job to start learning about the car.
Just wanted to know if that’s as easy as it looks? Is it simply a matter of removing the centre nut that holds the pulleys, as well as the bolts that hold the frame in place on the outside?
Once removed, I was thinking about having the parts media blasted and then ceramic coated. Any issues with this?
Is there anything I should look out for while doing this? Any do’s or dont’s?
Any advise would be appreciated.
Thanks.
Pretty easy job as described, obviously fan is attached to the alternator, so it may be a good time to have a good look at that while your in there, both the fan (excluding the pulley hub section) and housing are magnesium and would respond nicely to vapour blast, to make them look really schmick you can ceramic coat them and get the pulley hub section reanodised although that may be a step too far as it requires drilling out the rivets securing it to the fan.
Thanks 9er, I appreciate the feedback. I'm cool with drilling out some rivets. You then rivet it back together? Or use nuts and bolts? You don’t know of any vapour blasters in Melbourne do you?
cheers.
Re riveting would be the gold standard, but it's not easy finding the correct size, or a jig to set them correctly.
We ended up with a screw and lock nut arrangement on mine.
I think vapour blast is becoming a bit of a cottage industry, shouldn't be to hard to find one local to you
Very late on this I know but in case you haven't progressed I can offer some solutions.
Autohaus Hamiltons have a vapour blasting setup, and the proper riveting tool & rivets for a factory reattachment of the pulley.
Then send out the pulley (and any other CAD plated hardware) to be refinished.
Then select your preferred Ceracote applicator.
After vapour blasting and depending on the the condition of your fan & shroud, you may have to do some patching & fine sanding with JB Weld.
