Good Monring,

Does anyone knwo if its possible to get hold of the cam belt tensioning tool for a 1985 944? My workshop manual says its a dealer only job but I thought I would ask the question.

Regards

Hello,

While I am on the subject of belts can anyone tellme how much it costs just to get the belt tension done? Also how often do the belts need changing on an 85 944. Also one last question how much does a typical service cost from a specialist but not dealer?

I have just been to view a 944 and am very close to parting cash but need to know these figures before I commit.

Many thanks

Gary
 
I bet you could fine a million posts on here about belts

Anyway - new belts every 3-4 years, 45k miles, re-tension after 2K
If there's no history of a recent change, get it done as a priority - likely to cost between £3-400, depending on the other bits that might need doing - rollers, oil seals etc..



 
When I got my belts changed my specialist said the re-tension was free as it was all part of the service. I was under the impression it is a fairly quick job so I can't imagine it costing you that much if you were chaning the belts yourself and just wanting them tensioned at a specialist.

As edh has suggested there are many views about the replacement period but my handbook states for a turbo it's 40k mils or 4 yrs. I'm planning on erring on the side of caution and going for a 35k mile interval.
 
I thought officially it was 48k or 48 months, but I'm with Graeme and go for 36k (or 36 months; like I've ever had a 944 for that long without clocking up 36k miles or rebuilding the engine [:(])
 
Many thanks Guys,

I have decided to take the plunge and next Saturday I shall be picking up my 1986 944, a little birthday present for myself. I have beed through more than my fair share of cars but I have not been this exited about getting a car since picking my MR2 Turbo up from the importers. Maybe Ill grow up one day......maybe.

Regards

Fen you are correct about the official belt change interval but like you I prefer the relatively small bill for a belt change rather than risk needing a head rebuild.

I just looked at your profile - I'm considerably older than you and I haven't grown up yet where cars are concerned.

If it's the same as the S2 then no it doesn't keep the tension on all the time it needs to be loosened then allowed to tension then tightened up, did this with mine the other week but the spring was worn so had to manually move the tensioner and then tighten up.
 
Ok thanks for that.
I looked at mine the other day but it seems that it is nearly set to maximum anyway with only a small amount of adjustment left.
Could this mean it was slightly overtensioned when it was replaced so there will be no need to adjust it now perhaps?
 
Not sure of your situation but I suppose it depends when your belt was changed as to whether it has stretched, it does not need much adjustment to make a big difference to the belt though and be careful of which nuts you undo as one holds the tensioner to the backing plate and if this is undone as it is a bolt and nut the unit needs to come off for refit. From memory it is not the obvious nuts but the one in the middle of the tensioner and the other at the top right that need to be undone.
 
That tensioner is a right pig to wiggle out to retighten the nut too. Having made that error I know what a pain it is.
 
There is a good guide on how to do this in the workshop manual; shows which (2 of 3) nuts to undo, wiggle the belt to settle at the right spot and the right tension, then tighten the nuts. There are lots of health warnings around about not trusting the spring, need to use the proper tension measuring tool etc etc. Apparently if it is a new belt the tensioner will not set enough tension. Clarks Garage as ever has good diagrams and photos for the procedure.
 
The Clarkes guide is easy to follow and worthwhile using but make sure your cam pulley hasn't got two marks which look like TDC marks as mine has which really confused me for a while.
 
The auto tensioner isn't an auto tensioner, it only roughly sets the tension of the belt. You still need to adjust it with the gauge and then tighten the 2 locknuts. The springs do loose there springiness so worth watching out for.

You'll probably find that the auto tensioner isn't that accurate anymore.

If you join the club you can borrow the official tool from the club office.
