V70: General - Fitting new A/C belt

Jinxie · Feb 11th, 2018, 14:49

Hi all,

I have to get to grips with fitting a new A/C belt, in addition to the aux belt and the cam belt, 'cos that's what everyone says you should do. Anyway, I was kind of dreading the A/C belt fitting on account of it's a stretch belt that requires no tensioner which makes it a PITA to fit AFAIC. Anyway, done a bit of searching for a service tool that would make the job a lot easier and the Gates site threw up this pictogram (I hate them for their ambiguity!) which seems to imply that a special tool is not needed and one can just use a 3mm cable tie instead! As I said I'm no good with pictograms so if anyone can verify this is the case I'd be most grateful. Here are the diagrams in question which outline the procedure:

Is that what they're trying to say?

ITs a nice idea but it won’t work. The ac pump has a centre nut but this only spins the clutch not the pulley. The pas pump pulley is held on with 4 10mm bolts if i remember correct. You can’t use these to spin that pulley either as you will shear them no question.

The only way is either the correct tool, or bruit force. It took me an hour of swearing to get it on with my hands. It’s an awkward position especially if your doing it on the floor. When I do it again I’m going to buy the tool or just pay a man to do it.

How about blipping the starter motor instead, then?

I would say your asking for trouble, you don’t want to damage the new belt. When I wound it on with me hands it took a lot of messing about to get it sat in the correct place as it has to go over the lip on the pas pulley. There is a good chance you will split the new belt if you try and spin the engine on starter and it’s not seated right.

Someone might come along with a better way but I couldn’t think of one once I’d chucked all my spanners across the drive.

Haha! I know how you feel. I'm just confused by why Gates would advocate the use of a cable tie when I'm sure they'd rather sell those service tools they make for this job. I'm pretty sure I went through Gates' rigorous vehicle model version flow chart for my particular engine correctly and they of all people ought to know the correct method to install any particular product of theirs. :-/

Do they actually sell fitting tools though ? If not, they might be reluctant to recommend anything that could render them liable.

With a cable-tie attached to the belt, the fitter can't do any more damage [to the belt or the car] than they would by forcing the belt on by hand.

Starter motor ? No way, sounds very dangerous. Besides, if you've not got the auxillary belt fitted, if you turn the engine over, there won't be anything turning the upper pulley (aux belt goes on outer pulley, A/C belt on inner pulley)....or have I got that wrong ?

Take the auxilary belt off, so the PAS and A/C are free running and gently feed the stretchy belt onto the pulleys while turning the A/C pulley and pushing the belt carefully into the correct position. There's no need for any special tools and there is no damage. Replace the auxiliary belt and all is good. I used a Gates kit.
