How difficult a job is this for a keen DIY enthusiast. I have replaced belts on V8 range rover, fiesta, escort, suzuki jeep and vauxhall nova. I am concerned about the need to keep other parts of the engine imobilised when carrying out this job. Advice please.

Coach,

You need to be determined but it isn't rocket science. The trade time for this job is two or three times that of the usual diesel timing belt. What makes it such a pig is that, unlike "normal" engines, the timing belt is hidden away where the timing chain is normally situated on older engines...behind the front timing case cover.

This means that you have to drain down the cooling system, remove the water pump plus the alternator and power steering pump before you can remove the timing belt cover.

Oh and not to forget the crank pulley bolt that is torqued to a a whacking 350Nm, that alone defeats many that then arrive at our local garage for them to do when the owner gives up.

It is often worth removing the radiator if there is any doubt you might damage it when getting the crank pulley off and it makes overall access much easier.

Once there the job is OK-ish as long as you are happy to fabricate (or buy) the correct timing "pins" for the flywheel/inj pump.

The tensioning procedure is quite exact and there is an odd little procedure at the end to get the injection pump timed correctly.

I would say, given the hassle of getting it all apart, it is well worth budgeting for a new tensioner, idler roller and water pump. The last one I did needed all of these and it adds to the cost.

HTH

Thank you - I was not looking forward to doing this. I might just price the job locally before jumping headfirst into problems.
