I have to do the timing belt on my 3.5 in the next couple of months. Would appreciate if you could share anything like:-
How long did it take? (It will be first time for me with the Pajero.)
Do you have any special tools?
What sort of cost to expect for parts?
Any other problems or lessons learnt?
Anyway, good luck with your job & hope it went
well!
Cheers Roy

The correct way to tension these belts, compress the hydraulic tensioner SLOWLY in a vice and insert a pin, refit to engine with new belt in place and all timing marks in line, loosen tensioner pulley bolt and insert cir clip pliers into two holes in pulley, turn pulley anti clockwise until the pin is loose in the hydraulic tensioner (leave pin in), turn engine clockwise twice until marks line up again leave sit for five minutes, if pin is still able to be removed and replaced ie loose tension is correct.
Things to be careful of, if this is a quad cam the drivers exhaust cam will fall over when old belt is removed no big deal, but if is twin cam or one cam per head the drivers side cam will be just balancing at tdc and if bumped will fall over and this can some times push a valve into a piston so treat it carefully or have an assistant hold in position.
Also it is easer to hold belt on cam sprockets with large paper clip or bulldog clip.
Good luck
