Need help...! I am replacing my water pump on 2000 z28 (but it's the same as c5).
When I took the pump out, I noticed only 2 of the orange rubber gasket left where it should be. So I take that as the other 2 pieces of orange rubber are somewhere in the coolant system. So I tried taking apart the old pump as much as possible and found part of the 2nd orange circle rubber gasket material (see photo) in the thermostat spring.
I can't find the rest of the 2nd orange circle gasket and I can't find the 2nd rectangle gasket part.
What would you do? Is it ok to try flushing the block with hose water? How big of a deal is it that I can't find the remaining part of the old gaskets?
2nd of all... Are these bolts reusable or should I just buy new ones? I haven't tried cleaning them up. The top 2 bolts seem fine but the rest look not great
Any advice appreciated..
I replaced the water pump on my c5z couple years ago and didn't have to deal with this issue..

I would not lose a lot of sleep over it, I replaced my bad bolts (had them laying around) and I use small o-rings to hold the gasket on to the waterpump for ease of installing( on the bolts) !!!! bigger question is how did the silicone part separate after mounting ????
