The cooling system of your vehicle is responsible for maintaining a constant operating temperature in the engine system. This is accomplished with the efficiency of its working components and one important part to have is the 4 Seasons water outlet. This is the device where the thermostat is mounted and also serves as sufficient connection point for the upper radiator hose. The thermostat is a valve that plays the critical role of measuring coolant temperature. If the coolant temperature is hot enough, the valve opens to allow the coolant to freely flow through the radiator. On the other hand, if the coolant temperature is not hot enough, the valve closes in order to block the coolant flow, where it is directed through a bypass system. This bypass system permits the coolant to return back to the engine and allows the coolant to keep moving throughout the engine in order to balance the temperature and prevent hot spots. The thermostat housing is bolted to the engine and is equipped with a gasket or rubber seal to prevent coolant leaks. The 4 Seasons water outlet usually lasts for long and barely causing problems. However, as it ages, its deterioration will eventually lead to its demise and a replacement will be needed.
