Mercury PUMP HOUSING (118-3116)

Leaks are an obvious sign that your water pump is failing. Water pump housing damage can cause the water pump to fail, allowing fluid to leak from the system. When an engine overheats, you might think that the logical next step is to add coolant to help it cool down. While this is a noble gesture, it actually does more harm than good. This sudden and rapid cooling causes a thermal shock and can crack the water pump housing. The same can be said for running the engine after replacing the water pump and adding coolant. Allow your engine to cool naturally before adding fresh coolant if it overheats. GLM 12410, Mallory 9-43211, Mercury/Mercruiser 46-96148A1, 46-96148T1, 46-64141A1, 46-48743A1 are all interchangeable with the Sierra 18-3116 Water Pump Housing. Sierra products are designed to meet or exceed the specifications of the original equipment part they replace.
