Hi guys...have to put antifreeze mix in my FWC VP engine. Problem is it came with Propylene Glycol which of course i cant get here, so i have to completely flush the engine out with plain water then i can use Ethylene Glycol which i can get here.

How would you go about flushing the FWC side of the system out

Engine is 5.0 OSi GM SMB 305 (Half FWC system)
