Hot Rods What do you use for a radiator overflow bottle?

Not very sexy, just an old lawn tractor fuel tank. Drilled a hole just big enough for an interference fit to hold the tube snugly. Also, drilled a small vent hole in the cap. Works great.

 

Old military canteen for me.

 

I visited an Army Buddy in Georgia a number of years ago, he "donated" aluminum containers that held fragrance for soap that his wife made and sold at craft fairs. This is the second one that I have used.

 

Soda bottle.

 

Here's one I am piecing together. Aluminum tank from the auction site and a Moon cap and bung.

I updated the deleted photobucket photo with one HAMB friendly.

 

I have used an old Sodastream canister (used to make your own carbonated drinks at home) I found in the trash. Aluminium, about 2" diameter X 8", came with a vented brass cap.

 

Spun aluminum bottle used to test air monitors for breathable air in confined spaces. Thought it would match the aluminum radiator.

 

German army canteen.

 

About 10” of black PVC from the hardware store, cap on bottom with screw off top. Plumbed into bottom. I didn’t want one of those “milk carton” kits.

 

Had an old canteen with pouch. Mounted pouch so I can remove the canteen should it require emptying. So far that hasn't happened!
