Block Plug for Coolant

[ridiculously_necessary]

Does anyone know what that plug is called offically? Its the one with the ratchet head just to the right of the oil cooler. Mine has corroded out and leaked the coolant. I called Ford/Inernational and they dont see the part in their system. What about a part number? Or what about the thread size/type incase I can find a bolt to shove in there...

I just replaced mine. It is a 1/4 NPT. FYI, I used brass plugs with a nice big hex head.
The old ones are hard to get out....

I live in Alaska and the temps today have just now warmed up to 0. Will the 50/50 mix get you down to where I would need to be to protect against freezing.

why 50/50 and not straight or even a higher concentrate --- other than the obvious cost reason, or maybe that is it.

I believe 70% is the mixture that gives the best freeze protection, should say on the bottle. 100% will jell up at cold temps. There is a waterless coolant out there that runs in a non-pressurized system which I'm contemplating using. Advantages, never needs replacing, no water to corrode and plug your cooling system. Disadvantage (big), can't buy it in most cities so if you spring a leak you better have enough for a complete change in the back of your truck. LOL
