You clamp a catch bottle to the end of the hose then remove it at shows. You will need to vent the bottle and monitor it. Or you can add an aftermarket overflow return kit in a manner that makes it's temporary removal simple for a vehicle show.
These modern "Let Uncle Protect Us" laws can get rediculous! I ran an unbridled radiator overflow tube on at least 25 vehicles I owned from 1959 through about yesterday, when no bridle was required. Never killed a pet! _________________ Wes K

I, like most of us am very aware of the hazards of all the fluids we use in our hobby. We don't need uncle to care for us. We need to raise our offspring to be aware of their environment, educate themselves and act responsibly. On my small ranch I have 4 dogs, 3 cats and 5 horses and I am mature, educated and intelligent enough to care for them. I also have 6 grandchildren and trust me when I say those small guys will get down on the floor and lick antifreeze up with the same result. My Dad taught me the hazards of anti-freeze back in 1955. I taught my kids in the 70's and they taught theirs in the 00's. No uncle needed here. _________________ Wes K

From the Houston SPCA:
"To lower the risk to animals, you can switch to a brand of antifreeze containing propylene glycol, a chemical ingredient that is less toxic than ethylene glycol. In addition to being safer, propylene glycol has a bitter taste that makes it less attractive to curious animals. Although it’s safer than ethylene glycol antifreeze, propylene glycol antifreeze is still toxic. To reduce the risk of poisoning, all brands of antifreeze should be handled carefully and treated as a highly poisonous substance."
Try a brand like this:

One of the things I did to my M38 and M38A1 is to have both radiators hot tanked and pressure checked and bought new radiator caps of the proper rating for both. I've never seen any coolant dripping from either rad. Oil drips, yes - no coolant leaks. _________________ 1951 M38 |

In the neck below where the cap screws on is a small pipe.
Originally this pipe ran to the right side and down towards the
ground and was there if the fluid got hot and expanded and
overflowed the radiator.
In the sixties manufacturers began installing an overflow tank
usually plastic to catch the fluid.
Today's sealed systems still have an overflow tank but theoretically
as the fluid cools the level in the tank would equalize back to
the radiator with no actual loss of fluid.
Back in the day with overboard overflow it was another critical
check to make sure the radiator was at the proper level
before starting. Today no one opens their radiator cap.
Probably because most people don't even know what it is! _________________ Brian

My solution :
a part from an old nissan Sunny with a connection on the bottum.
The radiator is Always full with cooling fluid, the level in the tank is low when cold, high when the engine is warm. No coolingfluid drips anymore and always a quick levelcheck.

Yep,
That's the problem I have. Bubba cut off the original box but left the tray, then built a new battery box out of what, 12 gauge or something?
No room over there, so he ran the line across the top of the radiator and an old Zerex bottle sits between the rad and fender.
Real sharp, that dude.
heck, if I ever get that replacement box off I can probably use it for a stand to sit the jeep on it's so stout.
Anyway, that was why I was asking. To see what everyone else was doing.
I like Erik's idea. _________________ Brian

That looks like an MB/GPW fender and that bracket would be for the back of the headlight mount.
