A coolant overflow tank is a reservoir that keeps the excess coolant that is utilized in the system. Usually, it is made of plastic and mounted near the radiator. The tank is connected to the radiator with a special hose. When the engine is hot, the coolant temperature rises, so as the pressure. As a result, some amount of the coolant is released through a radiator cap. This excess coolant goes to the overflow tank and stays there until the engine cools. When the system cools down, the pressure in the radiator drops and pulls coolant back from the tank into the system.

Some Toyota 4Runner owners report an issue known as “the strawberry milkshake.” The root of the problem lies in the corroded radiator hoses that allow engine coolant mix with the transmission fluid. The mixture of the two fluids looks a lot like a strawberry milkshake. Hence the name of the related issue. The mixed fluid can be visible in the overflow tank; but if this cocktail returns to the transmission, the damage can be severe. However, regular coolant flushing and keeping your radiator components in perfect working order might help prevent the issue. If you are looking for a high-quality replacement, on our digital shelves, you can find a wide range of top-notch Toyota 4Runner coolant overflow tanks & components.
