My waterpump started leaking around the seals between it and the clutch cover. I removed the water pump without a problem, and figured I'd rebuild it since it is off. I can't seem to loosen the 2 phillips head screws that hold the 2 halves of the waterpump together. I've tried an impact driver too and have just about stripped the screws (thik they would use something other than phillips). Does anyone know if they are left hand threads? Is there a secret here? Thanks for yout help.
