Depends...TB interval is 70K for '98 and earlier (except '93 which was 50K). But from '99 and later the TB interval is 105K miles. The difference is between the ealier automatic tensioners and later model manual tensioners. You can go to <A HREF="http://www.volvousa.com" TARGET="_blank">http://www.volvousa.com</A> and click on the customer section to download manuals and other info such as service intervals but you have to provide personal information and register. So far, I've refused to do such. You may feel differently.
As MIJ pointed out the timing belt changes. The service rule of thumb is:<br>Every 60K is a HUGE service, tune up, flush all fluids, <B>At 60K you should service <B>the </B>transmission and clean the breather box<B></B> even though it's not listed</B>. <B>Doing these two importent items can literally save you thousands in the future<br></B>Every 30K is a major service, ie: 30K, 60K, 90K and 120K.<br>Every other 15K is a medium service: 15K. 45K, 75K, etc.<br>Every 7500 is a minor service, however, I would change the oil more frequently than every 7500K, I do it at 3500 to 4000 miles.<br>Besides being better for any car you can pick up <B>minor </B>things that are going bad and take care of them <B>before</B> they become a <B>major</B> problem<br>As for what you do for these services, it's in your owners manual.<br>If you don't have one, <B>get</B> one <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
JRL spells things out for you very nicely. I hate the new way that Volvo is "allowing" owners to have information. You want a hard copy of your owners' manual anyway. eBay often has them for a decent price. Check them out for your specific manual if you don't already have one, and keep it with your car. Never know when it can come in handy.
