Just ordered a new water pump and gasket after noticing some suspicious residue around my 15 year old water pump.

Flushed heater core with distilled water, (3/4" ID tubing, buckets and a small submersible electric pump) then low pressure (20 psi) compressed air. Seems pretty clean and free flowing. Sprayed parking brake cable bolts with penetrating oil in preparation for replacement. Unbolted water pump pulley & removed serpentine belt.

Flushed coolant passages in block/heads with distilled water, then low pressure air. Installed new thermostat and water pump. Interestingly, water pump leakage appeared to be due to oem gasket failure (which is thin metal sandwiched between some black material) between two upper water pump bolts on passenger side, rather than water pump shaft seal failure. So basically, I think I replaced the original water pump which was still good with 130K miles.
