Isuzu 4BD1 water pump grease nipple

Why and what grease would you use and how often should the water pump be greased?
When buying a replacement water pump does it make a difference to buy one with a water pump or not?

Any normal GP grease is fine, but don't overgrease it or you could do damage to the seal. One or 2 pumps when you do a service is heaps. And I think you mean "buying one with a grease nipple or not"
It won't matter, lots including the turbo motor don't have a grease nipple. It was only on the industrial motors as fitted to 4x4's.

Thankyou Brian, that clears thing up.
