Ghost Shadow Posted August 14, 2011 Report Share Posted August 14, 2011 Curious to know what intervals are recommended on timing belt change and what components are recommended. IIRC, on these new platform cars its 105,000 miles right? Thats only changing the belt and pump or was it belt, tensioner and pulley? i think volvo recommends changing some things but not all things. I just cant seem to find the answer. I check what service records i have to see if it has been done. i now have 158,000k and just started to hear a squeaking noise from under the timing belt area.

Keaton85 Posted August 14, 2011 Report Share Posted August 14, 2011 105k and its belt and both rollers. Water pump if you want but the Volvo pumps have been known to last 200k+. Its pretty much the same as the 99+ X70 5cyl. I can never remember if they have dual VVT or not. Doesnt really matter though as its easy to deal with the VVT. No need for cam holders.

Emiel Posted August 14, 2011 Report Share Posted August 14, 2011 Change the thermostat+housing too. sits between the cams and the tensionerpully. Can be a pita the get the housing of the thermostat, and the coolant hose of the housing. You don't want to change the thermostat afterwards Link to comment Share on other sites More sharing options...
Ihatespeedbumps Posted August 14, 2011 Report Share Posted August 14, 2011 Yes, the timing belt is due at 105k. You need to change the following. Timing belt tensioner idler water pump - thats up to you, replace if it's leaking at the freeze plug or has any play in it. Thermostat housing w/ gasket hose from coolant reservoir to thermostat CVVT gasket The little nipple that comes out of the thermostat housing is plastic and I don't think one has ever been removed without it breaking. Hence the reason for the hose and thermostat. You'll also notice that in order to unplug the ECT you'll need to remove at least one of the CVVT solenoids. This is the most difficult model to change the belt on, so give yourself plenty of time. Edit: Also remember that the 6cyl tensioner is moved CLOCKWISE unlike the 4 and 5 cylinder engines.

831t5r Posted August 14, 2011 Report Share Posted August 14, 2011 T6 timing belts are easy.just take little more work. And easiest way to do it is remove both bolts from right side engine mount and jack the motor up. Gives you plenty of room to do it. Then rest of tbelt replacement is like any other 5 cylinder Link to comment Share on other sites More sharing options...
jschaefer7406 Posted August 15, 2011 Report Share Posted August 15, 2011 The little nipple that comes out of the thermostat housing is plastic and I don't think one has ever been removed without it breaking. I broke the first one I attempted at the dealership, never broke another one after that. But yeah, they are a pain in the nuts for sure . It's little more time consuming, but removing alot of the ECU box and other crap in the area helps a lot. This gives you the room to bend the timing cover out far enough to avoid breaking the nipple off . Hose is a quick-connect, so you'll need a long pair of angled needle-nosed pliers to squeeze the two locks and release it. If not released, the timing cover won't even come off. It would be a good idea to at least order the housing so it's avaliable if you need it . As said, this is probably the worst Volvo to replace the belt on (only one that needs to have the coolant drained as well)... Good luck, hope this helps Joe Link to comment Share on other sites More sharing options...

Again thanks for the useful advice. yesterday was the most eventful volvo xc90 day i have had with this vehicle. Find out several things, inside the tb cover, there was a list of items done, and dated. i got as far as the picture below and saw it. nipple for the coolant is actually easy to get out if you use the proper tools. before i got this response i already removed the ecu box covers and removed the front motor mount bolts and used a wood block to jack the motor up a but to get to the acc tensioner. turns out that this car had a major service done already. timing belt water pump thermostat ect both top cam seals both pulleys and spark plugs changed all @ 114,000 in aug 08. this coincides with a carfax service date, but nothing was posted on the carfax stating what was done. the reason i was going to change the tbelt, i hear a squeaking noise coming from the tb area. i would spray water on the acc pulley, ac compressor, alternator is new, and the ps pump and the noise will not go away. concluded that the pulleys must have been failing inside the tb cover. when i pulled the cover off the tb area, i noticed that the pulley had a little metal shaving dust and would sparkle when light shines on it. i said oh there is the failing component, since the belt looks like a 30-40k belt to confirm the markings inside the cover. pull the belt, pull the tensioners to find out that it was not the tensioners failing. i immediately started to look for what pulley was failing...turns out it was the acc belt pulley. $300 in oem parts vs $30 and alot of labor. i decided against changing it since all this was done already. T6 timing belts are easy.just take little more work. And easiest way to do it is remove both bolts from right side engine mount and jack the motor up. Gives you plenty of room to do it. Then rest of tbelt replacement is like any other 5 cylinder good trick for also putting on the acc belt and tensioner. now that i almost did a timing belt/water pump on a t6 yeah it is easy like the 5's i have done before....but this one on a scale of 1 to 10(hardest) this is a 7.5 vs the 5 cylinder cars a 3 Thanks to all for the healthy advice, Link to comment Share on other sites More sharing options...
Ghost Shadow Posted August 15, 2011 Author Report Share Posted August 15, 2011 so first thing this morning i ran to the dealer and got this since they didnt just sell this $80 for the complete tentioner and pulley vs $41 for a aftermarket pulley, i think i did ok....not having my xc90 for a few days really make me miss it, driving the convertible with the top up really really sucks :) Link to comment Share on other sites More sharing options...
