A couple of weeks ago water started rapidly leaking from my Ford Fiesta Finnesse 2000 model (W Reg), i got this checked out and it seems one of the core plugs is damaged. What could cause this as im having trouble finding an answer? also, what is the best way to change the plugs?
The coolant in the engine can corrode the core plugs, so it is not unusual. The only way to remove the core plugs is with caution so not to damage the hole in the engine
