    Doing your own timing belt

    I've never done a timing belt on a LET before but quite like the 150 quid saving. My only worry is the tension on the belt after fitting, and does anyone have pics of the tensioner on the engine. Ive seen andys how to on z20let.co.uk but theres not much info on tensioning. Any info much appreciated. Doug

    i was in the same position - how-to was very vague, and ended up rounding the tensioner adjuster thingy

    gonna pay 20 notes for another tensioner, get sum1 in to do it and watch whats involved for next time!


    it may very well be easy, but without someone showing you first hand it may as well be the most difficult thing ever!

    I just dont want to balls it up, but i'm quite handy with the spanners and wouldn't see any problems with the mechanics of the job, its the tensioning of the belt. I have read there are marks to line up for the right tension, is this correct, any pics. Is it worth paying vx to do it, do you get a warrenty if your service history aint up to date.

    if you buy all the parts, then pay a garage to do it. shouldnt be more than £50 to do it.

    the garage i go to charge £30 to do my timing belt and water pump

    i would rarther pay them and if timing is out or belt jumps they will pay for any damage to head

    If you are pretty handy with spanners you shouldn't have to many problems, did mine the other week took just over an hour.
    There are marks on the tensioner and it becomes clear when you have it on and you can also use the old one for reference.

    There is a 'New' and 'Used' mark on it with a line for each.
    Once you have got the new rollers on put the tensioner on ( it bolts on straight through a hole in the middle), do it up finger tight.

    Put the belt on following the correct route.
    To one side of the bolt holding the tensioner in place is a 6mm allen key hole.
    You need to put the allen key in and rotate it 'anti-clockwise' as you do you will see the belt get tight and an arrow will come around and line up with the marks 'New 'Used'. When it is lined up with 'New' tighten the centre bolt and lock the tensioner.

    The part that makes it tricky is putting the allen key in at the correct angle, because if it is in at the wrong angle it will be in the way of the bolt and you can't tighten it.

    Hope this helps.

    Aye Griffin that does shed a bit of light on it, but i'm almost scared to do it myself incase it goes tits up. I'm sure its straight forward once you've done one, but.......

    Always wanted to know how you went about sorting the tensioner out.

    Yeah that's understandable you wouldn't want to get it wrong and maybe it's worth paying someone........ But as long as you are methodical and take your time I'm sure you would be fine. Good luck either way
