V70 P3 D5 Timing Belt change

[bobsy852]

So as my mileage keeps increasing (coming up to 103,000) now, I'm keen to get this done sooner rather than later, and its a job I'm hoping to do myself at home. Before I undertake the task though I have a couple of questions, so sorry in advance for the long post.

1. First question is a simple one, I guess the engine mount shown in this pic has to be taken out of the way? I can't see how the job can be done with it in place?


2. Now I know I'll need to take the Aux belt(s) off and they NEED to be replaced. (I'm under the understanding that there are two on these cars? One is a stretch fit, and the other has a traditional tensioner?)

One of the belts and its tensioner was replaced around 15,000 miles ago (before I bought the car) but I will replace this again with a new tensioner. However, I've read that I should replace all the pulleys as well. Is this true?

3. If I should replace all the pulleys I was looking at the air conditioning compressor & alternator:




As you can see they're quite close to the chassis and I've read I'd need to get a clutch pulley removal tool in there to get the pulleys off? This doesn't look like it'll be possible with them in place? Will I have to take them out if I need to replace the pulleys?

4. As for the timing belt, I'll be buying a kit from Volvo, and will most probably replace the water pump at the same time?
I've also already ordered one of the protection devices from Element on this forum so hopefully I'll be able to help protect it with that in the future.
The haynes manual doesn't go into too much detail about setting the engine to TDC but I presume it's fairly well marked on the crank and camshaft pulleys?

Thanks,
Rob

Have you seen this thread: http://www.volvoforums.org.uk/showthread.php?t=208501

I bottled-out in the end, and had it done at just under the 100,000 mile mark, at Hutton Brothers garage

Hi Martin,

Yeah I'd seen that thread. I'll be using that as my starting point.
However, that thread, nor any other I can find, mentions how to replace the pulleys for AC compressors/alternators etc.

I've briefly seen it mentioned by some member that it is advised. I was wondering if someone could tell me if it's necessary?
i.e, are the pulleys part of the failure of the Aux belts which then get thrown into the timing belt?

If so, I think i'll want to replace them for peace of mind. Just looking at the car without having taken anything apart though I don't see how I can with the in place?
Although looking at the link from Martin it looks as though the A/C and lower pulleys wont be that bad when the wheel arch liner is taken out. That alternator one though....?

Sounds all good, but I think you will find that the recommendation is to inspect the water pump and only change is there is evidence of any wear. If you do change it, I think it is essential that you replace it only with a Volvo pump.

Thanks Austin I'll bear that in mind!

I guess the question I'm really after answering is "should I change the alternator and/or air con compressor pulleys"??

The alternator pulley has a nominal service life of 80k miles but lasts longer. Mine was 160k ish but they've be known to become a problem at 110k or lower so will almost certainly not make it to your next timing change.

The ac pulley doesn't get changed, it's the bearing that fails.
Of all the causes of pulley/belt failure though, ac is at the lower end of liklihood and they more often than not give lots of warning.

These are the things to bear in mind so it's more down to your interpretation of risk.

Thanks Cheshire! I'll get the alternator pulley changed at least and I'll just inspect the AC pulley/bearing! Cheers!

I was wondering about the procedure of replacing alternator's freewheel clutch.

There is no enough space to fit the special clutch removal tool. Does the alternator need to be removed first ?

On our older D5s, there's a little more space and Volvo have a low profile tool which enables changing with the alternator in place but with the space available on later D5s, it looks like alternator removal is the only option.

That's not what the guys told me at FRF. I asked about alternator pulley and the answer was clear - there is no recommended schedule for this item - it is a case of checking during routine servicing. Having said that, mine was fine at 108k but I will probably have it replaced as a matter of course at the next scheduled aux belt change which is 54k I think, so will take it to 162k.
