Question Alternator change / V70 Tdi..

Hi everybody.. Happy New Year to you all..

It seems for the greater number of my posts about my 1998 V70 Tdi CD I'm in France with a problem.. ha ha..

To get straight to the point, my alternator is shot, and I've got to change it. I've got a new one coming from Germany at a very reasonable price, and with luck it should be here sometime next week, so.. I need to start getting my head into mechanics mode.

Now.. I've done just about everything to this car, including two engine rebuilds, so I'm pretty conversant with it, but.. being a really OLD guy now.. the old memory isn't what it was. So if any of you can refresh my memory as to removing the alternator from the D5252T lump I'd be most grateful.

I'm pretty sure the engine cover and steering fluid pump has to be moved, cos there doesn't seem to be a lot of room, to get what is quite a large alternator.. out.

Many thanks in advance for any ideas.. Dave..

Hey, Dave, many happy returns to you and yours for 2019!

Fortunately, in my personal opinion, our cars were over engineered so we don't have a great deal to complain about

If you slacken off the retaining screws/bolts that hold the alternator in place, one or two revolutions should do, and if you can get a copper mallet or engineers hammer to the head of the bolt before you completely remove the screw/bolt, that should release the captive/tapered nut on the other side of the bracket that will be pressed against the alternator housing. This should make for easy removal/refitting otherwise it will prove difficult!

Given your experience the rest should be child's play!

Good luck!

Many thanks Liam.. I appreciate your reply..

Yes, I certainly agree about the over engineering of these cars. That's why I want to hang on to the old gal as long as possible if I can.

Its a pity I can't say the same about my memory.. its not doing my experience with these motors any favours. The last time I did any major engine work was in the late Jan/early Feb of 2015. If my memory isn't playing tricks I'm sure I had to get the steering pump out of the way.. and that's definitely something that looks like the brackets were especially fashioned for getting the Audi/Vag motor into the Volvo.

Still, I'll succeed, I always do, and the alternator hasn't done bad. Its probably the original on 260,000 miles +.

If you want a laugh re my Tdi and its French experiences.. my mammoth thread on engine wrecks is here..

Many thanks again.. Dave..

You will need to remove the engine cover, the plastic air intake to ECU housing, the auxiliary belt and its idler pulley (which I think hinders access to one of the alternator bolts), the power steering pump and it's bracket assembly. You can leave the pump to one side, wrap a cloth around it to catch any fluid, and I think that should give you enough clearance to manoeuvre the alternator out.

Thank you very much for that Liam.. got it!

The brand new alternator arrived at my house here in France from Germany at dinner time today 5/03/19. I only ordered it yesterday morning. It was only about 20 dearer than used alternator's people were trying to flog in the UK. I'm really pleased..

I'll post when the jobs done. I'm up to my eyes and armpits in building a bathroom at the moment..

Dave..

Well.. I thought I'd give it a go and get the old alternator out late this afternoon. Bad move, after two hours and no joy getting the alternator out I had to walk away from it, and have a go in the morning.. what a pitta..

I've read a couple of other threads on the forum regarding this alternator removal job, and I'm glad I'm not alone in the frustration and bad language stakes regarding this job.

However.. I'm going to sleep on it, and apply a couple of suggestions in the other two threads concerning this job, mainly removing the headlight, and freeing up the radiator on the drivers side.

I love this old TDi, but there are a few things under the bonnet that definitely say.. this engine was bought in from Audi/Vag so expect things to be awkward to get at..

I'm off for a glass of wine..

Dave..

Cool

I've had two out and don't remember any major problem. What seems to be the holdup?

The hold up huron is quite simple at this moment in time at least.. I cannot remove the alternator from its place of refuge despite trying to free it using a myriad of different positions.

All the normal procedures have been carried out to give the supposed elbow room to be able to remove the alternator. I'm someone who definitely has infinite patience, but alas, I had to walk away from the job this evening because I simply could not succeed with said removal..

Alas.. hopefully after a nights sleep and a bowl of porridge for breakfast the task tomorrow will tackled with more favourable results gained..

Well.. I did it.. but what an absolute pig of a job. Made worse by a biting NW wind, heavy showers and mud!

As much as I love my old TDi, changing that alternator just about did for me today, and I'm damn good on the tools. Ok, the weather didn't help, but jeez.. it pointed out to me that there are certain things that try your patience, and then some, and this was one of them.

As for the bracket arrangement for the steering fluid reservoir/pump.. even Heath Robinson wouldn't own up to something like that..

I did end up taking out the drivers side headlight, and loosening off the drivers side radiator support bolt, (it snapped off), so I had to fashion a wedge to hold the rad in place. It worked and is secure.

So yes.. all done. The new alternator is in place and I can now go out after dark..
