my impeller broke, now there are shards in the system...what is the best way to flush it out? hose up the thermostat hose, do i have to pinch off the front radiator hoses first, then do them after the engine flush, can i leave the water pump off when i run the hose into the system...back flush? please, i love my boxster, and want to TRY to get all the junk out and SAVE it...please help
