I was just wondering if anyone knew how often the serpentine belt and fuel filter should be replaced on a 2007 mini cooper s??? Any help would be great, thank you!

 

Fuel filter = no service / replacement is specified as it's apart of the right-side fuel tank sensor assembly.

Accessory (Serpentine) Belt = every four years.

The fuel filter is part of the gas tank?

 

It's apart of the right-side [US-Spec passenger side] fuel tank level sensor submerged in the fuel tank.

To change out the fuel filter, does the tank need to be nearly empty? Or can i have a full gas tank?

 

Here's some info on replacing the accessory (serpentine) belt on a '07 MCS. The '07-'12 MINI Bentley service manual ($$) recommends this belt be replaced every 4 years, but I pulled mine after 6 years of use and 60K miles. The belt ribbing was seriously cracked, but the main belt structure and fabric webbing were undamaged.

The Bentley manual has you remove the right front wheel well liners, right headlight assembly, the hood latch support and the front grill. Unfortunately, after removing the last three items, you still do not have enough room to rotate your 20 mm wrench far enough to lift the belt tensioner into the "service lock" position. IMO, you would need to remove the entire radiator assembly and support structure to free up enough space. No room for a socket/u-joint setup either. Arghh!

This is much easier ... Remove the wheel liner. You have a good view of the belt and pulleys. From below, insert a stout wood dowell about 3 feet long (I used a 3/4") and position it against the bottom of the tensioner pulley. You can work it around the belt, but since I was replacing mine, I just cut it to get it out of the way. Push straight up on the dowell or use a floor jack to raise the tensioner wheel just enough (1/4") to push in the tensioner's "service lock" pin. Other than having to pull out and hang on to the water pump friction wheel's tension release strap (awkward), replacing the belt is straightforward. Just push the tensioner wheel up a tad to release the tensioner service lock.

 

I think i will check mine this weekend. 76k and no record or belt ever being changed (bought car with 50k).
Thanks for the tip.

 

I think I had mine changed already but I will look. Also on all but one of the 4cyl cars I have owned I just paid someone because it is just such a PITA.
