There are two types of catch cans. One, called an overflow, has the hose from the radiator going to the top of the can - this is a one way system and can not recover fluids passed from the radiator. Yes, I know that the factory unit is setup this way; however, it has an internal tube that goes to the bottom of the can/tank allowing for recovery. The other style is a recovery can/tank that has the hose connected to the bottom of the tank which allows the coolant to be drawn back as coolant system pressure drops to the point that the radiator cap opens to allow flow back into the radiator. And yes, I really should have titled this thread “Recovery & Windshield Washer Tanks”.
In all honesty, they are the same tanks that are setup two different ways. Here are two links to simlar tanks. I used the JAZ on this project.

One thing I assumed but did not mention. A recovery tank has to be vented to atmosphere at the top inorder to function.
