This is probably an easy answer for most of you. I'm in the middle of head work, sump cleaning, timing parts, etc. on my son's 2002 Saab 9-3 SE. PO took very poor care of this machine. Anyhow, I decided to update the water pump since it's so easy to get to! My question is, on the side of the water pump housing that faces the driver's side of the car is a connection for the hard line water pipe with o-ring. It appears that there is a bolt that goes in there to help hold that water pipe in place. Is there also a clamp or just a large washer that puts pressure on that water pipe? Can't seem to find pictures of this anywhere on the web. Thanks in advance!
