Timing Belt precautions!!
11 Attachment(s)
I am writing this post because there has kind of been a little debate lately about timing belts and the service intervals.
[/align]The post is to show why the timing belt should really be changed at about 70,000 miles instead of 105,000 like Volvo says it should be. [/align]Also Make sure you replace the tensioner and idler pulleys as well. [/align]I have some pics of belts I have replaced at work on cars. [/align]I have the belts from a few of the different models the milage will vary between 70K and 80K. You will see how the belts crack at that milage. [/align]I would not trust the belts like that on my own car. That's why I am making this post so that everyone is informed about the belts and what can happen if they break. [/align] [/align]I know not everyone has the money always to get the job done. I know how it is I have 4 kids and very little money. But the point I am trying to make is that it is better to pay between $700.00 to $800.00 or so. Rather than having to Junk the car or pay over $3000.00 to get the head rebuilt or replaced. Or maybe even more to have a new motor installed. [/align] [/align]I have my own theory on why they go bad faster on the 1999 and newer cars than on the older cars. [/align] [/align]I think it is because of how the timing covers are made. [/align]The older cars all the heat that gets to the timing belt only comes from the front of the motor. [/align] [/align]The 1999 and newer cars the timing cover are different because of having the VVT valve in the cam cover. That allows all the heat from the top of the motor to access the timing belt and add more heat to that area causing the belt to go bad faster. [/align] [/align]On the 1993 to 1998 5 cylinders and 1994 to 1998 6 cylinders the timing belts could last a lot long but I wouldn't trust them either. [/align]But that's my theory. [/align] [/align]Now onto the pictures the first batch will be the timing belt pictures with the model,year and milage that they were changed. [/align]Then the last batch of pictures will be an idler and tensioner pulley from a S80.(Not as bad as I wanted for an example picture but will work. [/align]Then finally a picture of an engine that had the belt break. [/align] [/align]This way everyone has an Idea of the entire situation. [/align]Then you can make your own decisions from here. [/align] [/align]The first belt is from a 2000 S80 with 72,623 miles [/align]Attachment 24184 [/align]Attachment 24185 [/align]The second belt is from a 2003 S40 with 73,746 miles [/align]Attachment 24186 [/align]Attachment 24187 [/align]The last one is from a 2001 V70 with 82,700 miles [/align]Attachment 24188 [/align]http://img.photobucket.com/albums/v6...Picture008.jpg [/align] [/align]Here is a tensioner if you look closely in one spot you will see where grease started coming out of the bearing. [/align]Attachment 24189 [/align] [/align]Here is the idler same here both sides were spinning grease out. [/align]Attachment 24190 [/align]Attachment 24191 [/align]If your serpentine belt looks like this replace it I have seen them break as well and get sucked into the engine and break the timing belt as well. [/align]Attachment 24192 [/align] [/align]So there is my post the pics might not be the best but should help some. [/align] Sorry here is the pics of the head and block.

RE: Timing Belt precautions!!
WOW, the pics showing busted valves sitting on the pistons are scary!
What is the reasoning for Volvo using the rubber belt instead of a chain? On the 1993 to 1998 5 cylinders and 1994 to 1998 6 cylinders the timing belts could last a lot long but I wouldn't trust them either. [/align]But that's my theory. 100,000 miles ain't what it used to be, it's barely broken in. Besides fluids, tires and brakes, most new cars go 100,000 miles before you have to lift the hood; even then it's just to change the plugs. I know not everyone has the money always to get the job done. I know how it is I have 4 kids and very little money. But the point I am trying to make is that it is better to pay between $700.00 to $800.00 or so. Rather than having to Junk the car or pay over $3000.00 to get the head rebuilt or replaced. Or maybe even more to have a new motor installed. And if they don't; the valves might crash into the pistons and blow the engine! Volvo should cover this maintenance at 80,000 miles; free of charge for all model years 2000 and newer. Today's consumer is not going to buy another Volvo if the engine blows on his 2002 s80 before it hits 150000 miles. He is going to trade it in on a Hondaand never look back. Meanwhile telling everybody the story of how the engine blew because a "belt" broke. Anyway, thanks for the advice tech. It is taken seriously. |
RE: Timing Belt precautions!!
This is hugely helpful to know -- thank you! I've got 102K miles on my V70 and won't wait around for 105K ...

RE: Timing Belt precautions!!
I have replaced the timing belt on my 1993 850 GLT every 50,000 per Volvo. The 1993 2.5L engines had a narrow timing belt than the 1994 and later. The car has +240,000 miles and when my daughter lets me, I still enjoy driving it. I bought it new 1993 as my company car. I just can't give it up. It still looks great and drive great.

RE: Timing Belt precautions!!
This is good advice, my Houston mechanic (Southwest Automotive Volvo Specialists) recomends having the Timing Belt changed at 80,000 since they have seen several break before the Volvo recomended time.

RE: Timing Belt precautions!!
I have a 2000 V70 crosscountry and it has 123,000Km or about 78,000 Miles and had my mechanic check it and it is done. How can Volvo recomend 160,000 Km or 110,000 Miles when so many belts wear out prior to that???????????????
|
RE: Timing Belt precautions!!
Probably to cut down the maintenance cost on paper to appeal buyers. The belt probably will last to the recommended 110k miles or whatever it is but Tech was onlyinforming us ofthe condition they could be at a certain milage. The ultimate decision will be you the owner. Thanks for the heads up Tech.

RE: Timing Belt precautions!!
Hey tech; what percentage of Volvo's you have worked on would you estimate the timing belt has given out before the recommended replacement? What is the typical cost of replacing a timing belt on a '01 V70 2.4 non-turbo?
|
RE: Timing Belt precautions!!
About 20% and about $400.00 to $600.00 depends on alot of things.
|
RE: Timing Belt precautions!!
I have a 99 v70 non-turbo w/134,000 and it was done at 112,000. I drive 4k a month all hi-way 70mph.I never race the engine.How long can I go?
|
RE: Timing Belt precautions!!
It will last atleast 70,000 miles from the last time it was done.

RE: Timing Belt precautions!!
Hi guys just booked my 2005 2.4 V70 in for its 75000 service and told them to give me a price to do the cambelt replacement
the reply was theres no reason to do the cambelt until the 100k service I phoned two dealers to get a comparible price on the service and was told this by both of them when I asked them do they have many come in with broken belts they both said they have never had a car in with a broken belt I would have thought they would have jumped at the opertunity to replace it at £340.00 but both said it would be a waste of money ????????????? is this a different belt than the ones in this thread ? |
RE: Timing Belt precautions!!
I doubt the belt is any different at all. Inspect the belt your self and see what it looks like.
|
RE: Timing Belt precautions!!
I dont understand the dealers reluctance to replace the belt at this mileage if there is / was an inherrant problem with them ill have a look before it goes in for its service thanks Tech

RE: Timing Belt precautions!!
Keep me posted.

RE: Timing Belt precautions!!
It doesn't look like the timing belt is all that hard to replace in this engine.
Can you see those small cracks just by looking at it with the cover off, or would you have to do a hard bend like you did in that pic to see what shape it's in? |
RE: Timing Belt precautions!!
You can see the cracks just by looking at it.
|
RE: Timing Belt precautions!!
Well, I checked it out today and i have the same kind of small cracks as in your pictures you posted, only I think mine may be a tad bit worse. I have 74.5k miles.
It doesn't look all that hard to replace the timing belt yourself. It looks like you just remove the covers, remove the S-belt, remove the crankcase pulley, and you can easily get to it. Does the block and pulleys have markers on them where they are supposed to be lined up to, and are the t-belt pulleys easy to replace? I can scrape up the money to get it done, but I'd rather try to do it myself if it's not that hard. I'll just do the t-belt, pulleys, s-belt and all the tensioners all at once as long as I'm doing it. I do have a second car to drive just in case. What do you think? |
RE: Timing Belt precautions!!
Its not all that bad pretty straight foward.
|
RE: Timing Belt precautions!!
Are there any brands of belts better then the other? If I'm going to do this, I want to get the best quality stuff I can so it will last a LONG time
