I replaced my radiator fluid this week. Now I notice a little fluid and grease at the nut on the cam shaft as it leaves the engine. I checked the nut and it was not very tight. Should I tighten further or should I remove and pack with additional grease before tightening? your thoughts please.

Yes, the nut I am referring to is the 1" nut in front of the engine. I believe that this is the water pump.

Please be specific with your questions so that we will be able to supply you with the correct answer.

If the water pump packing nut is loose you can tighten it a few turns. That will compress the internal packing and it should stop the slight water leak. Make sure that the grease cup is full of water pump grease as well.
