2012 Maserati Quattroporte Accessory Belt Change

Post by smellody » November 18th 2023, 12:51pm

Documenting this here as there are no web based instructions short of a Turkish made youtube video.

Last Tuesday on the way home from sushi 🍣, the Maserati started running strangely and there was a billow of smoke behind the car as I was heading home.

Shit, I must have killed the 4.7 liter Ferrari engine. . . The battery light came on and it steered like an old pickup truck. Thank God, just the accessory belt. I limped home and parked it.

As I couldn't find any decent instructions, I am writing it up here in case I forget over the next 60k miles.

Step 1: Order all the parts.
Image

Step 2: Source a local generic six rib belt because they sent two short belts.....
Image

Remove the under engine "beauty" cover. 300 t20 bolts and 4 Phillips screws.

Remove the air box. One 10mm bolt with sleeve.
Image

Now there is plenty of access.
Image

One pulley belt is 17mm. The other is 13mm. The tensioner is one 13mm bolt and has a pin to locate it to the block.

Replaced both idler pulllies and the tensioner.

17mm socket on a breaker bar to remove tension and route the belt.

This is the pulley that disintegrated and killed the original belt. (Causing all the smoke.)
Image

Generic belt diagram not correct for Ferrari.
Image

Correct diagram.
Image

Reinstalled!
Image

36mm socket to turn the engine to install the small belt.
Image

One bruise. Pinched my thumb 👍. Worth the cost though.
Image

Fixed! Now I can go to work Monday.

$1,100 saving. New belts, tensioner, and two pullies were under $300.

Happy Motoring!

Glad it's back to on the road, I guess this means you can return the rental. Looks a lot like the power steering pump that locked up on my truck a year ago. More time spent removing stuff for access than the actual replacement.

I dunno, that rental was pretty hot. It gave me a gosh darn chubby. Nice photo essay!

It must be difficult to hitchhike with that jacked-up thumb! 🫢
I'm kind of down to one thumb 👍.

Wondering if I can get a week off or at least some disability.
