Water Neck/Water Outlet Question

[Anonymous]

Hey Everyone,
Just a really basic question here....

I was given an old rusty and dirty Ford I6 motor today. I took off the water outlet to see if I could save it, and as I was cleaning it up, noticed it seems to be aluminum. The one on my car seems to be cast iron. Also, my old water neck has a little allen plug in the top of it that I have no idea what it is for....anyone know?

So, my question is....any reason I can't use this aluminum water neck? It looks better then my old one and seems to be an exact fit. I was told the motor came out of an old bronco. What, if anything would be the difference between the two water outlets, other then weight?

As always, thanks for your help...even on the simple stuff like this.

Warmest Regards,
Ryan

The standard water neck on 144-200 motors and all inbetween is generically often marked "W1" or "WO1". The 250s have a similar looking unit that bolts on, but the outlet is appreciably larger in diameter, as the radiator hoses are fatter.

The Allen head plug is for thermal vacuum switches; possibly other applications such as bleeding air, or fitting a direct-coupled temperature gauge will work.

Yes, you can use it.

There were several different T-stat housings/outlets, aluminum and iron, with different exit angles, and different O.D. sizes (1.25" for iron and 1.5" for aluminum I seem to remember?) for the 144-170-200 blocks. They are pretty much mix and match to meet your needs. I used late '70s aluminum outlets on my falcons, as the hose diameter is bigger and at a slightly different angle. This made hose selection easier during my cooling system overkill/upgrades. One had a tapped boss for a temp sensor and the other was nice and smooth. I don't think the flow difference between the two sizes would be worth mentioning as the T-stat is the bottleneck in the cooling system.

Thanks Guys! Just a little bit more for me to know about my engine. The guy gave me a complete 200 block and head. Unfortunately the head was removed, and had been sitting outside in the mud for so long that rust had completely taken over. It wasn't worth saving it to mess around with, or even to have a spare.

I turned the block in to my engine shop so I could hopefully get a core charge back. My old block was not rebuildable.

I appreciate all the help and support everyone here gives so willingly.
