Leakless water pump weep hole
I installed a "leakless" water pump on my '30 Coupe. It has less than two hours running time on it and leaks from a weep hole located on the mounting flange.
Anyone else experience this? |

Re: Leakless water pump weep hole
if I remember correctly one of the water pump mounting stud holes in the head is drilled all the way through the casting. Is water weeping around that stud? If so I've
seen people use RTV or gasket sealer on the threads to help seal them up. |

Re: Leakless water pump weep hole
I bought the pump from mac's about a year ago. I tried to call them but their customer service leaves a lot to be desired...
I was curious enough to press it apart. The bearings are all sealed and it has a mechanical seal that is spring loaded. I believe the problem is the seal allows coolant to to get around the seal flange and drain from the weep hole. I'll end up eating this and buying a quality part. Thanks for the help. |

You should be able to repair that pump now that you see what it needs.

Re: Leakless water pump weep hole
It must be one of these with sealed bearings
https://www.macsautoparts.com/1928-2...-845453-1.html Must have a weep hole to protect the sealed bearings. "The front and rear grease fittings are for show only. The bearings are the sealed type that will provide many years and miles of trouble-free driving. The seals are made from material far superior to the original as well." |

Re: Leakless water pump weep hole
A lot of pumps are a carbon and ceramic seal set up which are long lasting IE pool filter,dishwashers.

Re: Leakless water pump weep hole
It doesn't take a lot of ability to graft one of those seals into a Model A water pump - can't be - I've done it.

Re: Leakless water pump weep hole
I recently bought a new water pump from Snyder's. I compared it to the one purchased from mac's. The quality of the Snyder's pump was far superior to the Chinese pump.
Installed on car and no problems at all. I have another (expensive) paper weight and conversation piece. Thanks again for all of the help. |

Re: Leakless water pump weep hole
updraught, I need to itemize the bad parts and go back and do a group review...
I found out about them at a high price. I found a seasoned restorer and he put me onto Snyder's Antique auto parts. I have had great service and good quality parts. They are online. |
