    I worked at the plant for years and have fitted thousands of V6 belts - so have a couple of issues with the above:

    I. You should have the sparkplugs fitted when you fit the belt otherwise you will not be able to set the tension correctly!!!!
    2. The top roller you show with the grease leaking out of it - needs changing thats the fail mode - very rare to see a belt on the V6 go - its always the rollers first!!!
    3. The proper tool set (kent moore) has a timing gauge that goes onto the cam gears to set them correctly
    4. If you set the rollers up correctly - you get the timing set first time

    Top roller - set to 12 o clock to put belt on then set to just before 9 oclock
    bottom roller - set to 3 o clock to put belt on set to around 12 0 clock - nip up just as the cam gear starts to move.
    tensioner set to the top quadrant (as in pic) should come down to the centre mark once the crank is turned 2 revs - over tension will reduce the life of the rollers!!!


    there are also belt location and rotation marks on the belt - if you fit an aftermarket belt i.e Gates they have marks for the C25XE and the later bridge engine (2.6 & 3.2) with a none excentric bottom roller there is also a double mark for the crankshaft.

    i fit them for £60 plus parts (cheaper than the fitting tool £160 plus vat)

    a2reed, I used the Lazer locking kit the last time. It does have a timing gauge in it too, which isn't mentioned here. The Sealey one sounds better though, I just assumed they were all the same. I got used to it though and it came out well; if anything, the thing ran better with a new belt and tensioners.

    Interesting comment about the spark plugs, it never would have occurred to me that having them in or out would have any effect on belt tension. Maybe that's another reason why it took me four attempts :oops:

    Hi geffd.

    Is it possible you could send me a detail step by step guide on how to change the belt on one of these beasts?

    Would be very much appreciated

    Sounds like a useful tip. But what's the relation between the roller and the clock face? Is it that the furthest tip of the hex from the T12 is reference i.e. is this at 8 o clock?
