I have a 2001 Volvo Penta 5.7L GSI / DP and every year I have such a difficult time draining the block in the fall when I winterize because the drain plugs are in such difficult areas to get to and often are frozen. There are 4 of them. Has anyone replaced these with petcocks? I know its a 9/16 plug can you suggest where to get one. Please advise. Thank you!
