Last time I did the timing belt, about 2 years ago, I replaced the water pump (Hepu) and had a hard time installing the new water pump, keeping the gasket in the right position, as it would move and not align with the holes, as you have to do it blindly.
So I ended up using some glue between the gasket and water pump so that the gasket would stick to the pump and stay in place.
Since then, there is a small leak, and I have to refill the reservoir every 2/3 weeks or so.
Recently the car was at the shop for an unrelated repair, and was told by the mechanic that it's leaking from the water pump. He urged me to change it asap as it could damage the timing belt.
So I am going to take everything apart, and install a new timing belt and a new water pump gasket + screws.
Any tips from the more experienced guys on how to install the water pump + gasket would be appreciated.

I used hi temp RTV on both sides of the gasket, then placed gasket onto the dowels, then installed water pump. Pretty basic

I have a couple of the mounting bolts on the pump to keep the gasket in place as I guide it down to the mounting location. No glue for me.

Agree with Alvin,
I learned this trick from a pro.
I have done this trick for about 20 times, not a single leak.
when you deal with WP gasket, apply a thin smear of grease on both sides of the gasket:
- This ensures the gasket stick to the WP during install.
- Also, the grease somehow makes the gasket "swell" a tiny bit and the seal is always perfect.
never a leak during the last 20 years.
PS: RTV sealant can make things worse. If Volvo did not use RTV sealant at factory, why bother with it now?

I followed your advise and so far no leaks!
Thanks very much for your help.
