    Is this a planned periodic change or is there a problem with the coolant, if it is a planned periodic change and coolant colour is ok and not contaminated then :- Drain from the lowest point, drain valve on the coolant pump, make sure the cap is open on the header tank, you can try blowing through with compressed air or nitrogen, no more than 10psig though. Re-fill same amount as drained although you may want to keep drain valve open a while to get a few cc's of new fluid thru before closing drain valve, fill to 3/4 of the header tank and run pump to vent air then keep topping up as you get all air out before fitting cap back. If system is contaminated then you need to flush , you will have to contact local JCI Office for further instructions and parts.
