Get the hose to the bottom of the jar so it will suck coolant ack into the radiator while cooling off.

Other than that, SWEET.

I like that!

On the same topic, I have a vent hose that runs from the cap down down the side of the radiator. I assumed it was just a vent hose. I wonder if I could do this and it be used as a overflow?

It is just a vent hose...it vents your antifreeze onto the street.


Stick it in an overflow catcher of some type and make certain the hose goes to the bottom of the container so when everything cools down it will be sucked back up into the radiator.

P.S. My custom overflow is a very thick 1 qt. glass bottle from a local dairy.

Rad. cap listed

I have a cap on my f150 that should suck the overflow back into the radiator as it cools. I have the cap listed in the link below. I though it was OEM, from what i'm not sure. Please see #19 at the end of the thread.

https://www.ford-trucks.com/forums/1...low-kit-2.html

I agree that the hose needs to be at the bottom of the container to siphon.
Hope this helps.

Has anyone found a safety radiator cap with lever release, but expansion tank capabilities?

I just asked for a cap for a '74 F250 with a 390 at Autozone and this is what I got. It has the seal to let it draw coolant from the over flow and is working perfectly.
