What is the proper procedure to flush out all old coolant and replace with new coolant in an FD?
Thanks,

 

remove the coolant plug from the block. and remove the drain plug from the radiator. if you want to flush what little is left in the system. use disttled water and pour it threw the radiator. its normal to have a bit of old coolant left in the system.

 

What about an fc turbo ii same procedure hopefully

 

Not sure on an FC but you may get better feedback on the FC specific or the technical sections.
