time for a timing bellt and more? 850 1997

It's time for some maintenance on my '97 850R. I bought the car wiht 75k miles and now has 185k. All highway miles. I've never put on a Timing belt or hardly anything else for that matter. I got to thinking the other day I've got to get this done. I have a couple questions for all of you. I'm wondering if i should change the idler pulley. And also the water pump while everything is apart. The car has never needed a pump. While I'm at it I'm going to change the serpentine belt and probably all the coolant hoses as they have never been replaced either. Is it a good idea to change this stuff even though it may not be bad at the moment? IS there anything else i should consider doing while I'm at it? Am I going to need any special tools? Is there a good site with info on changing the belt? Thanks for the responses.

    Volvospeed "Bay 13" is probably your best bet for instructions. Lots of good pics.

    You might as well change the thermostat while you're at it. If it were me I'd change the water pump whether it looks like it needs it or not. It's not like on a 240 where you can inspect it every time you open the hood.

    So you went 95K miles on a 70K belt? Not bad. Google 'volvo 850 timing belt' and see if there are any good sites, besides volvospeed.com

    Yes, the tensioner pulley and idler pully are good to change. Water pump, just check it and make sure the shaft doesn't wiggle and no weeping. If you replace it, i suggest OEM.
    Yes for S belt also and idler pulley.

    If you are going to flush the coolant, get new hoses and clamps. Just don't tighten the clamps too hard, and try to put the clamps on the same place on the radiator tubes. Plastic parts don't like to be squeezed too hard. But this is a separate task and should be treated as such from the Tbelt.

    Buy a can of white lithium grease and grease the door hinges.

    Hi,


    I ordered the service manual (TP 2101201) Engines 850 1992 - onwards

    It has a really nice pictorial of changing the timing belt. I think that it was about $35 on www.volvotechinfo.com

    YES, it is time to change the belt before you read up on how to change your engine.

    Check out the T belt kit on www.eeuroparts.com

    If the water pump shaft does not wobble, then it should be okay. However eine Deutsches gebautes Pumpe ist nur $53 von Hepu, and they are pretty good. It is cheap insurance.

      No, 115k miles. It was replaced at 70k miles, at least that's what i was told and now 185k. Are you also saying the serpentine bet tensioner and idler pulley or where you saying for the timming belt? Guess i better baby it now till i get it changed, huh?

        Hi,


        The PCV system really isn´t on the way of a timing belt change. I´d leave it alone unless you are noticing symptoms (dipstick popping out) or have some money to spend. That small tube that goes into the air intake hose usally busts off, and really all the components should be replaced if possible.

        The timing belt kit has the idler and tensioner pulleys for the timing belt. Definitely a good idea.

        Sorry to keep asking but what about pcv's and an O2 sensor. Change those while i'm at it?

          When your mpg starts going downhill, then it will be time to consider the PCV and O2 sensor. If you have been using synthetic oils, the PCV is probably clean. The vacuum elbows will rot with age and need to be looked at.

          Do your timing belt and rollers asap. The tensioners are still good. I wouldn't do a water pump just because the belt is off. It only takes an hour to slip the belt off, so watch the antifreeze level. Using VOLVO antifreeze, while expensive, will make the pump last longer. If the thermostat is original, you could swap it while doing the flush as some of the fluid needs to be drained anyway.
