H2Opumpgrease
I have a leak less water pump. The rear brass fitting is greasable. One shot every 500 mi. or so. Question is, can I use a lithium grease (water resistant)or must it be the ''non water soluble'' type? Thank you.

Re: H2Opumpgrease
Ford specified to use regular wheel bearing grease. Water pump type or non soluble grease does not solidify and can clog your radiator.

The better option (which we used since I was a kid) is calcium-based water pump grease that is actually water soluble. Any grease that finds its way into your cooling system dissolves in the cooling water. It does not plug up the radiator over time. We always kept a separate small grease gun loaded with this grease for just water pumps. One supplier I have found for this water pump grease is Restoration Supply Company. They sell Lubriplate 115, made for water pumps. There are other suppliers, I'm sure. As with engine oil discussions, this topic is bound to get a lot of negative comments, but this is really what you want to use. "Waterproof grease" will get carried out into your radiator and plug it up. .

Re: H2Opumpgrease
What an interesting topic this is! There seems to be a lot of confusion about this among the mechanics and auto supply people I spoke to. I was aware of the radiator problems but thought that the water soluble grease was the culprit.
Thanks for the replies and to Jim #3 for the detailed info.I'll look for other possible answers but feel a little more sane this evening. |

Jim I looked up both calcium based greases and lubriplate 115 water pump grease. They are both water resistant greases not soluable. |

Re: H2Opumpgrease
I use regular chassis grease, Mystik JT-6 High Temp for the water pump. I don't over grease the rear bushing, and I unthread the brass collar, then pull the fan forward to make the impellor tight to the rear of the bushing, then I give the grease fitting just a little grease. Then I wipe a little grease on the front of the bushing and screw the brass collar just lightly snug. This has given me a completely leakless original pump for over 15 years, and I don't see any sign of grease in the antifreeze.
Notice ANTIFREEZE...............plain water is to drink.............antifreeze is to save the block. |

It was also always a very small shot of the grease.

Re: H2Opumpgrease
Curiosity question, but what is the "normal" operating temperature of water in a Model A Ford?
