I'm thinking about changing the timing belt on my 99 S70GLT, which has a VVT exhaust cam. I have read a lot of writeups for other models, but have not found one specific to this car. So I have some questions:<p>Do I need to lock the cams with a cam locking tool, or will I be ok if I turn the crank 90 degrees past tdc, then back up to tdc to unload the vvt hub?<p>If the exhaust cam or hub move a little after the belt is off, is it ok to just turn it back in position?<p>Will I need to remove the crank pulley to get the new timing belt on? If so I would probably rent an electric impact wrench.

Re: Timing belt change on vvt engine (bw77)

I just did TM on my 98 T5M (yours is different), here is my observations. It was a first time when I did it myself.<p>1. I used ipd locking tool and found it 100% justified the purchase. I would be to paranoid work without is. So I would say, yes you need it. <p>2. I was able to squeeze the belt without taking off the crank pulley. Surprisingly to take it off took me longer than install new one.<p>3. ipd instructional dvd is useless, don't bother..<p>Good luck<br>

Re: Timing belt change on vvt engine (Papa_Kirlo)

I didn't use the tool, and when I was finished and buttoned it all back up found that I was off by one tooth!! I had to pull it all apart again and had a 50/50 chance of making it worse or getting the correct tooth and luckily I moved the belt in the correct direction.<p>It is very easy for the teeth to move especially if you have to fight the belt off or back on. So, it can be done, but if I did it again, I would get the tool!<p>

So if you had to rate changing your T-belt for the first time... would your recommend it? <p>Rate it 1-10... 10 being the hardest.<p>

Re: Timing belt change on vvt engine (KBVolvo)

That's a hard one because everyone has a different level of experience. I would probably say it is between a 6 and a 7. I would also suggest replacing the serpentine belt and water pump while you are in there. There are some really good step by step instructions on Matthew's Volvo website. I would take a look at those and judge for yourself if it looks like something that you can handle. <p>Of course if I were to do it again, it would be much easier because of the learning curve of doing it the first time. But if you take your time and are patient, you should be able to handle it. There is one part that will most likely give you the hardest problem when you are removing the old timing belt, it can be difficult to get off because you have to manipulate it around some other guides but as the instructions state, keep trying . . . it WILL come off. And of course the biggest annoyance is that you don't have a lot of room to work in at all! It isn't like the old series Volvos where you could almost change the clutch from above the engine! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p><br>
