Mk2 Golf GTI Kjet Cambelt

Right after putting back together near enough everything barring a few hoses the fuel system and tensioning the cambelt.

Our next step is to tention the belt, all the timing is in TDC and we are confident of this, however we arnt very confident at the timing belt being tense.

The tensioner is in place but how do we actually tension this? its slack at the minute... we want the car to be running this weeked so it can be driven back to my house

Thanks,
Luke

u just tifghten the tensioner ,, youtube it,,, shd be 2 fingres wrth of slack to prevent strain
