Hello,

After discussing my coolant issues on this board and receiving great info, I have ordered a water pump along with some hoses to replace it myself on my 1990 760 GLE.

I already have the pump today and although it looks like the right one, is there a way to check that they really gave me the right pump for my car from the GMB part number? The reference on it is 190-1050 and also GWVO-05A. Just for the peace of mind.

Aside from that I have a couple pre-installation questions.

1) the torque. I have read that the torque used to attach the pump back on should be more or less precisely what Volvo recommends. What are the inexpensive ways to make sure that the torque is right? Is it such a big deal? (can't I just "tighten it but not too much"?)

2) there is a hole on the left side of the new pump. On the old pump, that hole has a bolt in it, in order to keep it closed. It happens that it's one of the leaky points. There is a hole on the right side but it has something plugged into it. However, the new pump does not come with that bolt to plug the left-side hole. Can one buy that? Or do I try to clean the old one and put it into the new one with sealant?

and I guess there's no number 3 for now...:)

Thanks guys.
