Expansion tank for radiator overflow

[AnthonyG]

Hi guys, just bought a nifty looking polished aluminum expansion tank. Going to use on my '35 and was looking for suggestions where to mount. Doesn't meet to be hidden as it has a great look. . 4 to 5 " diameter by 10" long. Flush mounting feature on dia. side.

trying to get a pic to show it.

It's not likely that anyone has mounted a similar tank on a 35 (but possible!). I would just mount it in a convenient location and make sure you can easily reach the drain lever.

This is what I have on my '35.....

That is a very neat installation !

Am I correct in assuming that in order for this tank to work correctly, a pressurized cooling system is required?

This looks like it's just an overflow container.
A coolant recovery tank works on a pressurized system that when hot can send overflow into the can and then on cool down send fluid back to the radiator.

Thanks, 51 Merc, that's what I figured. If this is the case with this tank (overflow container), why would one want to capture the overflow? A length of rubber tubing attached to the overflow tube would prevent any overflow spray into the engine compartment.....

Recovery tank helps contain the mess. My 36 loses coolant from time to time and without something to capture the overflow it ends up on the undercarriage. If the system is somewhat sealed, (good gasket and seal on the radiator cap), the expansion and contraction of the cooling fluid may in fact cause this set up act similar to a recovery system.

I put a plastic overflow tank on my 4 cyl A. With a tight fitting radiator cap (non-pressurized system), hose from the overflow tube to the tank. The pushed out coolant is drawn back into the radiator after sitting for a while.

Thx for the good info, and X2 for Flatheadfan's neet, neat setup!

I did the same on my F1. Used a S10 tank mounted by the radiator. Removed the bottom rubber seal on the cap but left the top one. Works great.

Thanks for the compliment! What I didn't mentioned was I pop riveted a case nut at the top and bottom for the tube brackets on the radiator metal surround. This makes the overflow tube easy to remove or install without having to bother any other components. As for the the two outlets on the bottom of the tube, I merely connected the radiator over flow tube to the short outlet and another hose for the longer tube overflow (never needed).

As the temperature drops at 155 degrees water from the container is drawn
back into the radiator. G.M.
