So... I'm doing the weekend timing belt - cooling system/water pump- accessory bushing replacement project this weekend ...except I ran out of weekend!
I am slow, meticulous, and cautious. Every thing has gone smoothly so far except for pressing in the new poly bushing into the wrong side of the alternator adjustment bracket! (time consuming correction!) The GMP water pump that I ordered from IPD came in a sealed plasic bag along with the engine block gasket and mounting hardware. I thought that was great until I removed the old one and realized there is a "gromet" type gasket on the top of the pump, where it meets the engine and another "ring" type gasket one the heater hose pipe. Neither of these gaskets were included with the pump. Are these to gaskets a "common" part I can pick up at my local parts store or Volvo dealership? (I haven't been impressed with my "friendly" local Volvo dealer's parts inventory pertaining to the 240 lately - believe it or not it's worse than the SAAB dealer for the same vintage car!) I have know idea how old the old gaskets are. Maybe they can be re-used, perhaps with the aid of some pematex sealant? Seems like good time to replace and be assuered of a good seal.
Another question... When I started removing coolant hoses, heater hoses and WP, I found quite a bit of corrosion in the system. Yes, it's been more than two years.. maybe more like eight or more(?) I flushed the system with one of those grarden hose connector kits, and actually connected it several different ways to flush out different parts of the system, but it still seems like there is potentially flaky-crusty stuff inside all of those pipes, ports, and chambers. At this point I am consiering using one of those Prestone flush products, where you drive it for several days before draining and finally replacing coolant. Any thoughts?
