Hi gang, been a long time viewer of these forums and have to say you guys have helped me out through out the years... A BIG THANK YOU!!!!... But I have an issue that has just cropped up as of last night... I got the Timing belt done 3 1/2 years ago via a Volvo main dealer it costed €749 .. my figuring was in the long run save me money... BUT (as the photo will show.. the timing belt last night came through the casing!!) Ive a couple of questions for yas ...

1. How did this happen?
2. is it an easy fix?
3. should I bring it back to the main dealer?
4. should I cry?

Love my Volvo and have done all of the repairs myself except for the timing belt

 

For some reason the belt has slipped off of its track. I am not savvy to V70s, but I can only assume that the hydraulic tensioner cylinder (or other components driven by the belt) has failed, allowing the belt to slack & slip.

I am moving this post to the V70 forum for better results. If you did not hear metallic clash noise, which is extremely rare & lucky, DO NOT start the engine. Have it towed to the dealer.

Only if the head has experienced damage then should you cry.

excellent I'll be putting it up on axles after Christmas, showed a mate of mine, and we think we rooted the problem to a belt tensioner guide? wont know till I get the part.. Thank you for the move!! As I am hoping someone has come across this issue, If not I'll do a step by step guide Merry Christmas All!!

 

Hi All finally got around to exploring the cause of the timing belt slippage and its not good.... I went to a Volvo garage 3 years ago to replace the timing belt they did... but thats ALL They did... they didnt bother changing the water pump, Idle pulley, or Belt Tensioner. The Idle pulley and belt tensioner comes as part of the kit they never bothered with the Serpentine belt either. Now comes the nasty bit The Garage is a reg Volvo garage, but seemingly the changed the name of their garage (one word and kept the rest of it) they said they went into liquidation yet they still use the same phone number, email, and website. and that even though I have a receipt theres nothing they can do.. Now back to the car.. 1999 V70 the timing belt has slipped (see pictures) and the Tensioner pulley is destroyed also the timing belt cover marking are no more (and thats not all!!) the cam shafts are out of line any ideas (even toying around with changing religions now!!)

 

why are the photos not appearing with the message ?

 

Hi Creep, sorry to read about your issues with your car.

Not sure how you are doing your photos but you can do it two ways. 1. Use the advance edit option and MANAGE ATTACHMENT, upload them there. 2. You can link to the photos from somewhere else on the web (you can copy and paste photos here from another website).

It is a shame that the shop replaced the belt only on your car. That is an option on the pre '99 cars because the belt schedule is every 115,000 km (70,000 miles) but on the '99 models the schedule is every 168,000 km (105,000 miles). Those rollers might last 230,000 km but will not last 336,000 km. Really a shame. Mechanics offer the "belt only" option as a 1/2 price option to customers that they grab most of the time but it should never be offered on the post '98 cars. I believe you can skip the water pump every other change but that's about it.

Now for your damage... If you was forced to find your problem because your car stopped or failed to start it damaged your head. If you was under your hood to check your oil or something and seen your problem you're likely fine. So if it caused your car to stall you have bent valves and have to get your head repaired or replaced.

 

Excellent RSPI the car was running but I notice I was losing power and there was the noise, from the engine, (I rarely have the radio on) and lucky I was in my drive way so I stopped the engine, and looked and could see the timing belt cut through the casing , If you look at my album you can the photos

 

I was uploading the photos to my album and then tried to link them to the message here so people could see the damage Im talkng about

From the looks of the photos and the updated info you added, there is a chance that you caught the situation in time to avoid damage. One is 1,000, I mean less than a 1% chance of doing that.

If the tensioner failed at the low speed and caused the belt to slip off the path which started the cutting process, that may have slowed the motor. Also, there is a good chance that the car jumped time a tooth or two which would have tossed timing off enough to loose power but maybe not enough to damage valves. As stated, you may be one of the few that was blessed enough to dodge the bullet.

What I would do is get new belt parts and rollers, replace everything in the path and see if it cranks (or have a shop do it). If it fails to start and run smooth, have a compression and leak down test done to see if the valves are bent. I wish you the best.

 

RSPI I cant thank you enough! Spot on, Ive had a few petrol head friends call over just a while ago and they all said the EXACT same thing!!!!!!! Even about getting the parts and Compression parts, I'll be doing it in my drive way, as a garage I normally use (has a lift and inspection unit, and all the tools is 36 miles away, its also heated!!) so I'll be doing it in the cold open air .. oh well!! But Im thrilled with the possible good news! my only question and I am nervous as hell about it, is the markings on the cams (there white markers which are not true markers) the real metal markers are out of sync to where they should be, would it be ok to turn the Cams by hand to line them up to the correct position would you say? Im worried about bending valves as you can imagine
