Default RE: Timing Belt Precautions!!

I wish I was that lucky. Timing belt broke on my S80 and now I don't know if I should count my losses or get it fixed. Interference engine ...wow...I will have to wait until after Christmas to evaluate the damage done.

Default What about the 2.5T engine?

The interval for the 2005 S80 2.5T engine is 120,000 miles. Is that too long to wait? Is this the same or virtually the same engine in the 850?

Does it have variable valve timing where it has oil running near the timing belt heating it up and accelerating its decay?

Is the timing belt and related parts as easy to change as on the 6-cylinder engines?

thanks

I would have the belt checked at 70k and take it from there.
Yes it has VVT.

Default Cam Lock For replacement

Is there a tool to lock the cams in place when doing the belt replacement, I have seen them for other Volvo models on IPD, but have yet to find one for the S80, I think I want to tackle this myself, but dont want to fu$k up the timing on my car. Cuz the stealership wants $782 to do it (without the water pump being replaced) and I am not about to spend that kinda dough if I can do it myself.

If you mark the pulleys and cam cover before removing the belt there is no tool needed.
You can make a mark on the back of the pulley and one on the cam cover inline with the one on the pulley and just make sure they line up when going back together.

I have a silver sticker on the passenger side of my engine that says 107k belt or something or other...is that for the serpentine or the timing belt. It's a big silver sticker on a black cover.

To help you distinguised,A timing belt or cam belt is a part of an internal combustion engine that controls the timing of the engine's valves.It is also used for the more general case of any flat belt with integral teeth.

Hey Tech. I am new to this, and see where several people read my post\question regarding replacing a valve in my 99 S80 2.9L turbo - but nobody seems to have any suggestions. My friend has a lot of experince working on Toyota and Audi autos, and was hoping to find some helpful tips on Volvo's with this process - do you have any helpful ideas? Thanks so much.

Newbie here - Bought 2002 s80 non-turbo with 80,000 miles. Car well cared for, dealer and non-volvo mechanic said, "wait until 100K before changing Timing Belt - Read these posts and decided to insist on it being done. The old timing beld had a crack through it and could have broken at any time - Glad it was changed

I just had to rebuild the top end of my mom's car due to the beltbreaking with only 26,000 on it. 5 valves bent, 5 pistons with hit marks on them. Previously done by a very reputable shop. I could find no reason for the breakage. The tensioner bolt had already been "upgraded", the belt was not dry or cracked, but it had clearly ripped in two. I guess all I am saying is it isn't even safe at a 50,000 mile interval. I work on Porsches for a living and am very familiar with timing BELTS on interference engines particularly on the 944's. IMHO The S80 is a time bomb. After this experience I will be replacing the belt on my S70 EVERY year regardless of mileage

I had the dealer replaced mine at 110,000 and just recently at 205,000. All went OK the first time, but the service engine light came on after the second replacement. The dealer claimed this is unusual (how many times have we heard that) but because of wear, the engine needed to be "pinned." You gussed it, the job had to be redone. I got some break on labor and parts, but needed a new cam shaft and related seals. The old belt and bearings look OK. Lesson to be learned: there are side effect to replacing the timing belt. Knowing what I know now, I could have just drove the car till the belt failed and then put in a new engine. A new engine would have saved me the cost of new oxegeyn sensors too.

Hi,

The 2004 Volvo S80 I am driving has 73,000 miles on it. Do I need to worry about the timing belt right now? The car is a 2.5t awd and runs great with no weird noises. I understand better safe than sorry but 73,000 is well under the 120,000 mark.

Thx
Chris

That car should be done at 105k by what Volvo says. But I would check it.
