Rescuing my Volvo after 3 years parked

[jbg]

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.
