coolant drain

[jyothi]

Hi all, I'm trying to flush the coolant in my VY Commodore (pretty obvious in this section of the forum!!!!) and just need to know which hoses to unplug. Please help!!!
Thanks

switch temp to hot incabin, and just remove the lowest hose from the radiator and release bleed valves and radiator cap. invest in a workshop manyal they are very useful.

To flush it properly your suppose to go the opposite way of coolant flow. Remove the thermostat and the top radiator hose and stick your hose down the into the block.. that flushes the system out properly. Thats if ya think there's a blockage or something in the system tho.
