If the coolant recovery tank has a hole in it, what is the proper fix?

When the coolant recovery tank has a hole in it, replacing the tank is the most appropriate and effective solution. The coolant recovery tank is essential for the proper functioning of the cooling system, as it collects excess coolant from the engine and allows it to be reused without losing fluid.

If there is a hole in the tank, it compromises its ability to hold coolant, leading to coolant loss and potentially causing engine overheating. Simply adding stop leak may provide a temporary fix, but it does not address the root problem of a compromised tank. Additionally, doing nothing is not viable, as this could lead to severe engine damage due to insufficient coolant levels. While plastic welding might seem like a quick fix, it is often not reliable, and the integrity of the tank may still be compromised.

Thus, replacing the tank ensures that the cooling system can operate effectively and safely, maintaining proper engine temperatures and minimizing the risk of damage.
