Front diffuser rust

Hi all,
Anyone had the black paint peeling off directly behind the two front lower diffusers.
What would you suggest? Removal of bumper,primed and re-painted.
Seems to be just the very edge about half inch all round.
Thanks

Hi Gary, do you mind to post a picture so we can better appreciate the damage?

Gary- That area is probably either composite or aluminum, so there should not be any rust. Corrosion, maybe, if aluminum, but not rust. Not too much steel on an F430, except for idrivetrain and suspension components.

Gary,

I assume you mean the intake grilles which are items 12 and 13 (circled in red) on this diagram. If the car is under 4 years old they should be covered by warranty if the paint is flaking and causing surface corrosion.

You can view the original diagram on Eurospares website http://www.eurospares.co.uk/partTabl...A=2&B=19994&S=

Yes thats correct,sorry didn't know the terms.
Yes right behind the grill there is a small steel lip which has rusted so i need to do a decent job on it.
No warranty.

If it's only these steel lips, then it's a very easy job Gary just brush them with a small steel brush or sand paper to remove all rust and repaint it with anti-rust paint, then finish with black paint and there you go

Do you have to remove the bumper/fender or do the grills come off without?

Yes Gary, you have to remove the front bumper to access these grills from inside as shown on this picture.

Removing the front bumper isn't difficult but you may need a second person to help you removing without scratching it. If you need, I can document how to remove it

Removing the F430 front bumper

Here we go :

- Remove the front wheels
- Remove the lower parts of the wheelhouses
- Detach the front section of the underfloor from the bumper (6 screws)
- Unscrew the nuts (1) fastening the bumper's side to the chassis brackets and remember to keep the side plates (2)

- Gaining access from the luggage compartment, remove the grommets (3) against the bumper's fastening nuts

- Unscrew the nuts (4) fastening the bumper central part to the chassis

- Before removing entirely the bumper, detach the spray nozzle supply line from the headlight washer pump. BTW the rust you have there may come from a leaking hose which passes right under the grill.

- Remove the complete bumper, retrieving the gaskets (5) and the central spacers (6). The gaskets (5) must be replaced to prevent water leakage.

Refitting the F430 front bumper

- Reuse the original central (6) and side (2) spacers
- Fit the strip along the upper edge of the bumper
- Reconnect spray nozzle supply lin to the headlight washer pump
- Check the span and alignment with the body which must be 1 mm along the entire upper profile of the bumper
- Tighten the nuts (4) and (1) and, if needed, tighten also the nut for the adjustable fastener (7)
- Attach the underfloor panel back to the bumper using the 6 screws

Tightening torques

Tightening of bumper central nut : 40Nm
Tightening of bumper side nut: 20Nm
Grille retaining screws: 3-4Nm
Underfloor section fastening screws: 6Nm


Good luck

Gary- I guess Ferrari could not resist the temptation to put something on the car that would rust. Stainless or a coating would have prevented that.

Stef- Your F430 WSM is much more complete than mine. Where did you buy it?

Terry, as I wrote once, I think I bought at least 10 different versions of them and reassembled everything myself after having decrypted all the source pages. Also, I completed my custom assembled version of the WSM with many other missing info and pictures.

Stef- Now I remember. You should sell your version. Ricanbi did the same thing with the 575M WSM and it sells pretty well.

Thanks Russ and Terry. It's a good idea but I still need to finalise some chapters in such way that the WSM integrates also some of the wiring diagrams when needed (instead of 2 totaly separated software parts) + complete some of the info and integrate "real life" corrections. I'll let you know here when it's ready
