will this rad overflow can work?
Looking for a cheap nice looking radiator overflow catch can for my 68.
When I bought the car there was a hose going from the hose barb on the radiator cap to the ground.
Stock cans are too pricey.
Looking at summit and fleabay there are a lot of overflow catch cans but some are not vented, some have the in & out fittings on top??? and a drain on the bottom.
Every car I have owned has the in and out on the bottom/ cap on top so the radiator can push and suck in fluid when needed.
Am I thinking correctly? how could the radiator suck the fluid if the fitting is on top??
Will this style work? fiting on bottom and top. Could plug the top one and put a hose barb on the bottom.
Thanks

The can will work, but you will either have to leave the cap loose or leave the top port open for a vent/overfill opening. You could put a hose on this just for spillage to the ground.
All your pressurizing should still be handled only by the radiator and the radiator cap on it.

My 70 L46 has a surge tank. Would that mean the original radiator was aluminum? It was replaced before I bought the car so I don't know what's in there now.

There's another thread going on about the same subject and whether or not an overflow tank is needed.
I think for my application I didn't want the fluid to drain onto the pavement or my shiney frame/engine so I'll run an overflow (surge) tank to catch any extra fluid. I'll have to leave the surge tank vented so the radiator can push/pull the extra fluid.
I think I've got that right.
