Volvo Parts Connect.com states “selling genuine Volvo replacement parts”.
For a new manual window regulator (88 240), it charges $63 (shipping $11).
For front brake pad ---$19
For timing belt ---$10
For timing belt tensioner ---$6
They are very cheap!
Can I trust this seller?

More and more dealers are getting in on the online sales.

I'm going to try http://volvopartslisle.com next time I need dealer.

They are near Chicago and were a few $ lower than Tasca on a few things I checked.

Looks OK, but you're off on that $6 tensioner (MSRP is $66.87)

See PN 463633.

Thanks, Bruce.
Actually, the OEM tensioner spring is $6 and the tensioner is $39.

My genuine Volvo water pump has been 112K miles with no leaking (I keep the belts a little loose), but I think it is about time to shop around for another one.
