Coolant recovery systems

[73TopBanana]

Hi All, would a stock coolant recovery system be useful? After a drive, can see underneath some coating of antifreeze on the chassis.
Any suggestions? Thanks

First make sure you don't have a leak somewhere; then check your radiator cap (they are cheap insurance) to make sure it is working properly e.g. holding system pressure as it is supposed to do.  Auto parts stores do sell universal overflow (recovery) tanks though.

Thanks for you help

They're a good addition. Do you keep topping up the rad? They will usually stop overflowing when they reach a certain level.

For a non-recovery system, you don't fill the rad completely up to the top.  There is usually a little flat "shelf" under the cap that indicates the fill level.  That being said, it's not a bad idea to add one if you aren't concerned about looking stock.

There are no leaks, i do fill to correct level and have correct cap.
Thanks for the help, i will decide what to do

[Mrbill426]

Not to  but correct cap because it is working properly; sealing properly?

Yes it is, i may be getting paranoid for nothing, thinking about it, could just be a small amount of antifreeze that comes out of the overflow tube
Thanks

You could just put the tube into a holding tank so it doesn't go on the floor. That way you have an idea how much is coming out of it.

True, thanks

While perhaps not being the most aesthetic, it wasn't un-common in the day to see, as a puke tank, a beer can with the overflow hose stuck in it. If you're going for Day 2 authenticity, that may be an option.

@jimynick That must have been a Bruce County thing. You never saw that where I came from.

Lets see...how many cars made in the last 40 + years don't have one ? The point of the recovery system is to keep air out of the cooling system.
When the coolant heats up and expands it goes into the tank. When the coolant cools down it gets sucked back into the radiator. The radiator is completely full at all times. Beer cans etc... were to keep coolant off the driveway, garage floor ( and mandatory if you went to a race track, coolant is slippery) etc... Regardless you need a properly functioning cap. A very common cause of overheating is a cap that does not hold pressure.

You can get a repop on ebay. https://www.ebay.com/itm/223335692273
