One thing to remember is that if you are going for a recovery bottle, you will need a special radiator cap, that has valving to one bleed the coolant into the bottle and two to stop air being sucked in, instead of sucking fluid back. Standard caps don't have this valving and suck air back. Tridon CA0750 is one such cap.

Thanx all. Food for thought. Think I will keep it simple and go with an overflow tank.

For the odd time the rad gets a little hot, right now I have a hose running down side of radiator and on to ground. Not good for environment.

I just want to catch the fluid.

After 3 years trying and often failing to keep the '72 from overheating, I mounted a 1-1/2 qt. Moroso tank on the firewall in place of the heater, using the heater plumbing and running the cap overflow to a plastic bottle. All my cooling and burnt valve problems went away.

Why not just use a late style factory tank, brass , and shine up quite nicely.

Just be aware, I've seen first-hand two of the late expansion tanks fail with a burst due to corrosion along the bottom seam from the inside-out. If going this route, I would consider having the tank inspected/tested or start with a new tank.

There was a similar post on here last week which I cannot find but instead of a glass overflow bottle how about a non polished aluminium can.

I have tried to get a better image of the writing on the can without success so it is as follows;

"This beer takes its name not from a bird but a car, the much loved, paint-spattered MG factory run-around known as the "Owld Speckl'd Un" Our Master Brewer uses crystal and pale malts and a blend of Challenger, Pilgrim, First Gold and Goldwings hops to deliver a beautifully malty ale with subtle notes of toffee and fruit. Especially fine with English roasts, Sausages and Pies"
