Engine: coolant overflow tank

[leonard]

hello I'm looking at a 17" polished over flow tank from JOHNNY LAW MOTORS. I know my 64 cruiser needs a over flow tank I just did not think there enough room for one until I saw this one I guess it fits on the side of the radiator.any of you guys use this product? thanks in advance for your input.

THANK YOU JAY for the info. LEONARD

My R2 Hawk has a cheesy FLAPS plastic overflow container that has never caught a drop of coolant in the 11 years I've owned the car. I have kept it in place "just in case". One of these days I'll probably replace it with one of those fancy "billet" canisters since it just doesn't look like it belongs under my hood.

If you mean something like this, I've used a couple over the years and they do the job. Available pretty much everywhere. I don't see a problem with using one.

I have one of those on the Yellow POS since 2000...
Works OK... Keeps things clean.
One thing to note.
You need to run a closed cooling system cap on the radiator.
Early 'open' system caps will burp out the overflow tube, but suck air in through the cap.
A 'closed' system cap will burp into the overflow tube, but suck back through the same tube.
That way, any air in your system will get purged out through numerous heat/cool cycles...

What deepnhock said. You need a special cap that fits both depths of the radiator.

Anyone know exactly what cap that is...........brand, part number , pounds of pressure etc.?

15 lb. cap commonly used on U.S. built cars of the 70's & 80's. Coolant recovery bottles by then became commonplace whereas the original type used by Studebaker by now are harder to find.

One point though in the O.P. is the "rubber hose" was not on the radiators when they left the assembly line. Studebaker radiators had a metal line from the radiator cap neck, across the upper tank & down the side to the bottom. When they were recored most shops replaced them with the rubber hose. It was easier in assembling the upper tank to the core & commonly found in the "big three" cars. I have a couple of the original radiators with the steel line still attached. I put this in just so those who might be more in tuned to originality might want their car was, in case of it being judged at a meet, it might (or might not) get dinged a point.

The top tank is the expansion tank on the older downflow radiators, so you shouldn't really need an extra expansion tank.

Newer crossflow radiators DO need an expansion tank.

Stay away from Johnny Law, it's low end Asian crap.

i aint got no puke tank on any of my Studes. What makes you think you need one?

Avantis tend to run hot and they "puke" very quickly after shutting down in hot weather. I like to put in as much coolant as I can in an Avanti, but I got tired of seeing a puddle of antifreeze under my '64 when we drove cross-country in '03. Pep Boys plastic tank fit nicely on the right side of the radiator and it solved the "puke" problem. Other Studebakers have never been a problem.

[DEEPNHOCK]

Any engine will run at a more consistant temperature if there is 100% coolant in the system, and no air.
A coolant recovery tank is just one method of purging air out of the system without dumping any.

Heck, if we are going to say what was there is good enough, lets just say that the water tank on an old farm pump engine is fine

I'm wondering if some are overfilling their radiators. The radiators of the Studebaker era are meant to be filled only to about half full in the top tank. If your filling to the top it's gonna force some out of the overflow when the engine (cooling system) is hot. Steve Greer
