Topic: Water pump

[Mustang64]

Hi everyone,
I had a little leakage on my 64 1/2 water pump, so I decided to dismantle and change the gasket.
I noticed one bolt was missing out of 9, that could explain the leakage.
I noticed also the the outlet on passenger side, towards the cylinders block was fully tapped with white sediments (look like salt). I cleaned everything but I'm wondering :
- how it could worked like this
- why it was tapped on passenger side and not on driver side
taking into account that on my 2 years ownership I always used the correct coolant (yellow/green colour)
Any answer will be the most welcome
Have a good day
Didier

To help everyone, which engine are you working with? U, D, C.........?

Sorry, it's a V8 code D

I assume it's the "deep cover."

Using the pic below, which hole?

Consider a replacement kit from AMK products https://www.amkproducts.com/ Look up kit - F-487. It's for a 289 with an aluminum pump, no A/C (a different kit is used for A/C) consisting of 9 bolts - $25.00. Knowing how time is the enemy, it is not surprising of the residue you found. Because of your location, shipping might be a problem. Check with them.
I've used the AMK kits on several of my 65-66 Mustang projects and am satisfied.

- why it was tapped on passenger side and not on driver side

It is tapped on the  driver's side and the tapped hole goes all the way into the block. From best to worst.

- The previous owner left the bolt out.
- You might have a bunch of junk in the tapped hole (corrosion).
- The bolt broke off inside of the timing cover bolt "tunnel". When corroded the bolt likes to break an inch or so from where it screws into the block.
- The bolt broke even with the block surface.

Hi everyone,
Thanks for your answers
jwc66k,
Digging in my own reserve of bolts, I was able to find the correct one, so no worries
You are right : time is the enemy. This car have been stored in a garage in southern California from 2010 to 2020. Then sold and shipped to France but didn't move much up to dec, 2021 when I bought it. I had the relevant problems : change of seals, gaskets, hoses...
Bossbill,
There isn't broken bolt, just a missing one which explains the leakage and the sediment deposit
Indeed there is corrosion inside
I was thinking of using a radiator cleaner from Bardahl to clean the whole cooling system ; what do you think ?
Have a good day,
