View Full Version : cam belt tentioner

Tuesday 17th May 2005, 22:37
i took my 95 t5 estate to my favorite mechanic today to have a new cam belt fitted but he soon realized that allthough changing it is no problem it does have a hydraulic tensioner and in the book it says that you fit the new belt ,leave it for 5 minutes then fit the tension testing device and it has to be within 2.5-4 marks on the gauge (this is a volvo only tool which doesnt give a tension reading in pounds so the device that the mechanic would have used to set the correct tension can't be used) so he suggested that i take it to a volvo dealer where they can check the hydraulic tensioner is working properly. this is fine but volvo main dealer prices are astronomical. does anyone know of a way that the tension can be checked correctly or what the tension should be on a normal gauge? or does anyone know of a mechanic not far from stratford upon avon that has the volvo device? if not does anyone know if the tensioners ever need changing?
my car's done 156,000 but looks like its had 2 belts already. any ideas on this would be gratefully recieved. if not i'll just go to volvo and get ripped off!
thanks craig :bog:

My V70 should apparently have the tensioner changed at every cambelt change.

I seem to recall, but don't know why, that on 850's, the tensioner should be renewed every other belt change so it may be worth just renewaing the tensioner.

I don't know it that would still require the special Volvo tool though.

The VOC have a tool loan facility for members. If you're a member they may be able to help but the site is dead at the moment for some reason.

Hamish at VT did the automatic tensioner and the cam belt on my V70 T5 last week for a fraction of the main dealer cost.

thanks guys
i suppose it would be safe to just change the tensioner aswell then ,thats assuming the new hydraulic tensioner is working properly, but surely if a faulty tensioner were to cause an engine smash then surely volvo would be liable anyway? or is that just wishfull thinking ?
by the way rich how much did it cost if you dont mind saying.

Mine doesn't have a hydrolic tensioner on it, from what I recall its off a later/earlier car. Being ex plod you're never quite sure what you've got.

Does the V70 t5 have a hydraulic tensioner? How difficult is it to do a cambelt change with the hydraulic tensioner?

Change the tensioner if you have one!!!!!
I didn't and it went plop, slipped 4 teeth, bent 10 valves, upset poor spesh!
Non of you lot want to go through any of this as it a pain takin the head of grounding in new valves rebuild again, lucky I done this work my self, but the parts cost an arm and a leg and a foot, so please change the god dam TENSIONER!!
