Thats good to know. I didnt know that coolant flows through the heater core even when the heat is off.

So if I use the garden hose Ill spray through the thermostat housing. Ill get one of those filters from wal mart too.

The small amount of tap water wont harm the engine down the road? Im assuming the hose water will remain in the block. Does anyone know how much the block holds by itself?

Also, I will definitely back flush the radiator and heater core. I have 88K miles so Im sure that theres some sediment in there.
