Coolant flush

Re: Coolant flush
Running the engine will not purge all the water out. As long as you flush long enough where water can say go in the radiator and then out somewhere on the engine (like a disconnected heater hose) you will get pretty well purged. Keep your opti dry during all this.
If you remove the thermostat and put the housing back on, you can flush with the engine off, as the thermostat won't be there to block flow to/from the radiator.
