The cooling system is the ever-reliable buddy of the engine along with its own components to allow safe, efficient and accurate internal combustion cycle. Simply put, it stops the engine from overheating even with tons of heat produced. It regulates this amount of heat so some of it ends up used in the combustion process while the remaining amount would be digested off the air. Of course, for this system to be effective and efficient with its function, it uses liquid coolant to absorb the heat by circulating around it. The liquid coolant is stored in a container-like device, called expansion tank or sometimes called coolant recovery tank. It is attached to an overflow tube connecting through from the radiator filler neck to the bottom of the tank. The tube is where the coolant flows back and forth. When the engine is running and the cooling system has to collect heat, the coolant expands and flows out of the radiator and into the expansion tank. As the cooling system starts to cool down, coolant will go back through vacuum and into the cooling system. Coolant liquid is drawn back by vacuum to keep air out of the cooling system. When the expansion tank starts to be inefficient, it needs to be replaced to resume its efficient and effective function. When looking for a Jaguar expansion tank replacement, it is important to remember the same specification of the old one to avoid trouble during installation.
