    Idler Pulley bolt size?

    Gang - In a bit of a tight spot; On the way home tonight the car started screeching...got home and looked at the pulleys, thinking it was a bad belt or pulley... sure enough - the idler(?) pulley bolt had worked itself out and the arm was rubbing against the adjacent pulley (water pump?)

    Anyone know the bolt size?

    That's the tensioner, not the idler pulley.

    Looks like you need:

    11. Hex bolt: M8X105 07119904532

    12. Washer: 11287835130

    19. Protection cap: 12311713143

    It looks like you have a hydraulic tensioner, whats good about those is replacing the pulley on it is really cheap, while you're down there you can replace both the idler and deflector if needed for like 30-40 bucks.

    Awesome - thanks... Now I just have to see if my local dealer has them in stock tomorrow morning. Looks like I’m borrowing the wife’s car tomorrow!

    Ended up ordering a new bolt, washer and cover from FCP Euro... Shipping via next day delivery was offered at a discount so I went that route. Fortunately my wife is out of town tomorrow so I have the use of her car for another day... Hope to fix this Saturday.

    I also spun both pulleys with the belt off and they spun well, so I’ll leave that expense for another day. OEM BMW tensioner pulleys are $50 now.

    Thanks again for the help!

    Chris,
    There are (3) bolts that connect the hydraulic tensioner to the oil filter housing. It looks like the tensioner is very close to the water pump pulley. If that is the case you are probably missing one of the other (2) bolts. Just a fyi, hate for you to get in there and find out you need more parts.

    Thanks man... I actually felt around the housing and the other two bolts were in place. Iíll definitely check them for tightness when I put the new bolt in (still hasnít arrived; looks like FedEx failed FCP Euro this time.)

    Just thought Iíd add that Iím disappointed in FCP euroís customer service; I emailed them last night, and the response to my question asking what theyíre going to do about it was essentially Ďhereís your tracking information.í -No apology for the inconvenience or offer to credit me for the shipping or anything. Surprising, actually, because ordering from FCP euro has previously been a good experience. I realize the shipping problem is not really their fault, but they should be seeking a credit from FedEx and passing it on to me. I paid for something I didnít receive (expedited shipping) and it pisses me off.

    Now my car is dead in the water until Monday night, because the only time I had to do this repair was this morning. I have commitments for the rest of the weekend and have to work on Monday, so I canít do it until Monday night.

    Hello Chris,

    I'm sorry to hear that you didn't get your order in time. I'll be happy to refund the shipping you paid on the order.

    You can email me your order number - davidg1@fcpeuro.com

    Please let me know if there's anything I can help you with in the meantime.

    Regards,
    Dave

    Dave - Thank you. Email sent...

    Nice to see responsive/ responsible customer service like this.

    I placed another order, FWIW... Discovered my tensioner bracket was actually broken, which I think is what precipitated the bolt failure. (Bolt actually snapped, not loosened, and fell out.). I gooped the bracket up with some JB Weld and crossed my fingers. Hope it holds until the replacement bracket arrives.
