Flushing the engine when exchanging coolant?
The post subject says it all... how to flush the cooling system most efectively when exchanging coolant...
I used to drain the system and then put in aprox 3 liter of water and started the car... after 2-3 minutes I turn off the engine and drain the systm again and then put in the coolant...
Is this the right way or is there something more efficient???

What motor is it?
B Series has a stem valve that you could open and start the car to flush your coolant with water. I dont know if D series has that.
For D Series, your idea sounds good enough.

Take it to Valvoline and let them do a complete flush-cycle and refill for $60. They'll give you free coolant for the rest of the year too

What I do is...
1. Drain coolant
2. Remove thermostat
3. Use garden hose to flush block (Wal Mart has a little plastic fitting that makes this easier...I just use my hand)
4. Replace thermostat
5. Refill Coolant
Also make sure you catch all the flush water.
