Default Parts help!

I am getting my parts order together and I need help with 2 items:

I cannot easily find a water pump o-ring. I am sure there are thousands of sites that sell them, but I cannot confirm what is the right one. Can someone please reply with a site with a known good o-ring?

The timing belt idlers I am finding are referencing the idler's bearing as a replacement part. Not the entire idler as the part. I am not against that, replacing the idler bearing, but I'd like to know what the bearing ID an OD measurements are. Can anyone provide me this information?

For example, Rock Auto has 2 bearings:

15mm x 35mm x 11mm or 20mm x 47mm x 14mm. I don't have the idler here to measure. If anyone could help that would be super, thanks!

Thank you ngoma,

That link was very helpful. The part number it lists for the sealing ring is 1257197. That seems to be an OEM number for it. I've also found 035 121 043, 035-121-043, 035-121-043-INT, 035.121.043, 035121043, 22554044589, 35121043, and N90133901 from IPD, Pelican Parts, and FCP. I was trying to find an OE number as a cross reference for the other numbers.

Our own v8volvo mentions in a thread from ~2019 that the "[w]ater pump o-ring part number is 035121043. Available online for under $2 or the dimensions are 98mm x 4mm if you want to find one off the shelf."

I used that number, 035121043, and I typed it into Rock Auto's part number search and I found an Elring o-ring P/N 091723. The description for this part listed the following cross reference numbers: 035121043, 1257197, 12571972, N90133901. All three of these match numbers I found elsewhere, and your OE number. The best part is that the Elring o-ring is $0.99!

There is also a BECK/ARNLEY 0394021 which has the same cross reference numbers for $2.99/ea.

Okay, scratch that. I did find some idler pulleys. Rock Auto carries INA and SFK, and a few others. You can find them by searching for 069109243B or 1257120. I believe that the second number is the Volvo OE number.

Hey gang,

Well not much to report regarding the Volvo. I did just now place my order for parts so that's something. This summer is looking pretty busy but I'll be picking away at getting the car in shape. More to come!

Well some parts are beginning to show up so I'm back posting about the Volvo.

Hey v8volvo, back in April you posted this comment. Can you provide more information about other methods on loosing the timing belt, other than slackening the water pump mounting bolts?

Fun to watch the progress!

Regarding loosening the timing belt -- the primary method of course is to slacken the water pump and slip the belt off the various rotating components, yes.

It's also possible to remove the belt by leaving the water pump in position and removing either the cam sprocket or the idler roller. This can be done for the sake of variety or, in some specific situations, it can be advantageous for making a job more efficient.

(For example suppose you are wanting to only replace a crankshaft front main seal or oil pump gasket, yet you know the timing belt and water pump O-ring are recently new and do not need replacement and timing/tension are where they should be already and you wish to not disturb them: in this case you might save time on reassembly by leaving WP and cam sprocket in place, checking injection timing using dial indicator prior to reassembly, marking belt and sprockets, removing idler pulley, replacing the crankshaft area parts needed, then reassembling per marks and verifying timing returned exactly to where it had been. By doing it this way you skip all the steps of removing/replacing the valve cover to time the cam, removing/replacing/retiming the rear timing belt, setting front belt tension, removing/replacing water pump to change the O-ring due to its position having been disturbed.... etc.)

The reason I say "preferred" method is that once you're accustomed to doing it a particular way you might continue, even if there's no specific advantage. For example I am accustomed to removing the cam pulley first (after setting TDC of course) and using that method to remove the belt. Why? I guess I like it a little better because it allows me to first remove the belt and a few other components (crank gear and dampener, most of the tin shields etc) before letting loose an antifreeze shower when the WP is freed up. Fewer things to have to wash.

I have been able to minimize the coolant deluge by draining it first by (my preferred method of) slipping a 1/2" tube (directed into an empty coolant or milk jug) over the outlet nipple and opening the valve. This valve/nipple is on the coolant hose connector junction below the vacuum pump.

Good point, very true. I guess I sometimes forget about that move because both of my cars have had that nice plastic tee with the integral drain nipple replaced with the 240 style metal tee with no valve. If the valve is there then certainly that makes sense as the easiest way.
