How to Know Your coolant recovery tank system?
Caps and the filler necks into which they are screwed should be inspected periodically; look for deterioration of the rubber gaskets, broken springs, corrosion, dents or cracks. Provided the proper cap is used, a recovery bottle can be added to any closed cooling system. Regular inspection of the bottle is key.
What are the signs of a bad coolant overflow tank?
Here are four of the most common signs of a bad radiator overflow tank. If the radiator coolant overflow tank is damaged or cracked, then you can expect coolant fluid to leak out of it. Sometimes cracks will form on the overflow tank if it is too old and worn out.
Do you have to fill coolant recovery bottle?
The recovery bottle should not be used to top off or fill a cooling system; that must be done via the pressure cap. Once the bottle’s full, however, it will serve as a valuable level indicator. Note the level of coolant in the bottle when the engine’s cold.
What does it mean when your coolant tank is leaking?
If it sinks lower, the engine is leaking or consuming coolant. If you are forced to top off the coolant in the system repeatedly, or if the coolant level never moves within the bottle, it indicates that a problem exists. If coolant is needed, don’t add it to the bottle; the system should be refilled using the pressure cap.

Which is the highest point in the coolant system?
An expansion tank can easily be recognized by the neck and cap used. Since the tank is under pressure it will require a pressure rated cap and neck, (Shown right). The pressure relief in the expansion tank should be the highest point in your coolant system.
Where does the coolant go after the check valve?
When a high enough vacuum is achieved, it overcomes the second spring in the cap, the one that’s associated with the check valve. Coolant flows from the recovery bottle, past the valve and back into the engine’s cooling system, keeping it full and air-free.
