Hi all just changed the cam belt on my mh fiat 2.8 jtd, fairly easy to do? Hardest bit engine mounting, anyway warning to all i thought these engines have a self adjusting pully wheel they dont, they have a manuel self adjusting pully tensioner. How to adjust, if you steer hard right and drive up a small ramp ie the yellow fiamma type you will have room to do?? No wheels off or jacks needed. Remove bottom shroud cover 1 ten mill nut then 2 17MM nuts, then look up into the engine just high of the bottom pully to the right you will see a 17mm nut loosen it of a bit just to give slack, this will allow the adjuster to take any slack up in the cam belt then re lock the nut back in place. Make a note of how many turn you turned the nut to loosen and turn it back to the same and a little bit more if you like, make sure you lock tight it. If you over tyten it distorts the plastic shroud and can make it rub.if you under tyten it the roller will fall of and the belt will to and reck the engine?? Anyway hope this helps my cam belt was very loose and i was lucky it never sliped a tooth but i replaced the lot anyway. No special tools where used only the bottom pully nut is a 36mm socket and i used a snap-on hammer wrench so didnt need to lock engine??to loosen the big nut at the bottom on the pully wheel. If you only have spanners wrenches sockets etc you will have to lock the flywheel there is a tool but a well placed bar screw driver tyre lever etc in the flywheel should hold it, get someone to hold it in place as you wont be able to do 2 things at once. But this is only if your replacing the belt. Make sure you lock all the timming marks up as well. double check use paint marker etc. And when done make sure you turn the engine over with the 36mm socket a good few times, NOT BY THE CAMSHAFT before you start it. Hope this helps someone or saves there engine all the best all. i can not be held responcible if you mess it up sorry.
