    You are thinking of the 3.0 engine which in theory does require the body off but it can be done with some difficulty with the body on. The 2.7 fuel pump belt does not need to be timed but the 3.0 is timed, so some work is required in a tight spot.

    There are two timing belts. Front, cam timing belt and rear, HPFP.

    It will be about a three hour job for someone who knows what's going on. It took me six hrs for the first one I Did. That was including redoing the HPFP one as the belt was incorrect and the tensioner didn't take.

    The 2.7 is a bit easier in regards to the HPFP belt, but you need to wind it on by turning the motor over. The 3.0 is a bit easier to slip the belt on, but it needs to be timed and has a special tool to hold it in place. You have to be careful though as there is a gap in the plastic which the tensioner tang can locate in instead of its actual slot, if it doesn't locate right the tensioner won't take up properly.

    The cam belt is the same for both engines.

    I would replace all pulleys while there and maybe the fan belt tensioner. The water pump can be done when ever as it is located outside of the plastic timing cover.

    As above, replace the water connector while there, it's a 5 min job once everything is out of the way.

    The only other thing to check with the timing cover off is the oil pump. If where the timing belt tensioner bolts to doesn't have a brace between it and the to bolt hole of the cover, it needs upgrading. Probably just do it to save an oil pump failure in the future.

    You will also need to drain the coolant. Easier way it's via the fuel cooler.

    It's not a hard job to do yourself, as long as you have a degree of mechanical ability.

    Belt kits are around 300-600 mark, Gates are the genuine brand.

    Technically there is only 1 TIMING BELT at the front. The rear belt is not timing related.

    I had 4 quotes but half the workshops are saying my car has 1 belt and the other half are saying it has 2. As a result the quotes for the job are between $2400 and $3800 depending on the number of belts that need replacing.

    ive been told the pulleys and water pump should also be replaced.

    Can anyone shed some light on their belt replacement and how many bloody belts my car has.

    Cheers

    Yes for the 2.7 but the back belt for the 3.0 is timed so two for the 3.0

    Gee, just had my belts replaced 2 days ago. It's SDV6 so not the same. 2 belts but possibly a more fiddly job due to timing and access issues. $1870 from the dealer and I got a discount of ~$200 on top of that a/c being a member of a local club the dealer sponsors.

    Thanks for all the info everyone. I’ll get the additional parts replaced as per your suggestion.

    To the guys that got the job don for less than 2K, I wish I could find someone that could match that. I’ve gone to dealers as well as Indie and cont get a better price than I’ve mentioned

    I can see what you are saying, but..

    On the 3.0 it is timed. Thus the timing tool to lock the pump.

    With the 2.7 you can unlock the engine once the front belt is done and wind the rear belt on, but with the 3.0 you must leave the engine locked up and fit the rear timing tool so the HPFP does not turn during fitment.
