Im replacing the water pump in my 1992 toyota celica, and i cant get the pully off! i have been working hard for like an hour, i took the belts off. all i have is good old fashoned sockets and crescent wrenches. do i need to get the pully off? and is it lefty loosey and righty tighty or righty loosy lefty tighty?? because sometimes i hear they reverse it. thanks- jordan
