A faulty water pump can cause engine overheating and damage due to lack of coolant circulation. Three checks can be performed on the pump. First, squeeze the upper radiator hose when the engine is warm; a working pump will cause a pressure surge. Second, inspect the pump's "weep" holes for coolant leakage, indicating a seal failure. This may require a flashlight from underneath the vehicle. Lastly, a squealing sound or movement in the water pump pulley may indicate shaft bearing failure. Don't confuse this with drive belt slippage, which also causes squealing. Replace a defective pump immediately.

Pontiac Water Pump maintains continuity of coolant flow, which removes excessive heat, thus keeping the engine at ease. In 1926, Pontiac made its identity by transforming the mundane into the car-handling punchline, and that philosophy of a low-slung, hard-grabbing, and corner-carving ethos, and even as the dashboards got new technology, the brand remained focused on fun, not on the grandeur of the parade float, and the cars retained a cockpit-like feel where the wheel, shifter, and gauges were right in front of the face where a quick look or flick lightness was also a hallmark of Pontiac, with heavy cast components being substituted with aluminum components to sharpen throttle operation and narrow the handling. The Water Pump is now available in either belt-driven or electric models, both pushing coolant in engine jackets to the radiator to cool the engine, and although the first cast-iron housings worked well, lighter aluminum castings save weight and rust resistance, and redesigned impellers and larger passages push more volume with each turn, cutting temperature spikes during traffic snarls or quarter-mile bursts and releasing a portion of the horsepower usually applied to overcome the work of friction drag. An electric Water Pump responds to sensor inputs, increasing flow as revs increase and moving off on highway coasts, hence wear reduces and efficiency increases. On any Pontiac, the quick way to a more stable temperature and a minor addition to pushing power is to change to a performance Water Pump.

First, squeeze the upper radiator hose when the engine is warm; a working pump will cause a pressure surge. Second, inspect the pump's "weep" holes for coolant leakage, indicating a seal failure. This may require a flashlight from underneath the vehicle. Lastly, a squealing sound or movement in the water pump pulley may indicate shaft bearing failure. Don't confuse this with drive belt slippage, which also causes squealing. Replace a defective pump immediately.
