My water pump leaks when it gets hot but I am unable to determine where it is leaking from. I think it is the upper seal that is worn out. It is not either of the hoses. I plan on loosening the engine mounts and raising it up on a 2x4 which will be enough clearance to drop the water pump bolts and change both of the seals. Other than draining the oil and antifreeze first, am I missing anything? I'm bound and determined to get this 345 in perfect working order so I can try out my new powerflow bagger and gator blades. I have already changed every pulley, belt and spring on the deck. I'm currently working on changing the pto clutch, the main drive belt, main spring and all of the pulleys.
