What are the ways to check the operation of the water pump while it is still installed on Chevrolet Caprice?

A failure in the water pump can cause serious engine damage due to overheating as the pump will not be able to circulate cooled water through the engine. There are three ways in which to check the operation of the water pump while it is still installed on the engine. If the pump is suspect, it should be replaced with a new or factory-rebuilt unit. With the engine warmed up to normal operating temperature, squeeze the upper radiator hose. If the water pump is working properly, a pressure surge should be felt as the hose is released. Water pumps are equipped with 'weep' or vent holes. If a failure occurs to the bladder of the pump, small amounts of water will leak from these 'weep' holes. In most cases, it will be necessary to use a flashlight from under the car to see evidence of leakage from this point in the pump body. If the water pump shaft bearings fail, there may be a squealing sound at the front of the engine while it is running. Shaft wear can be felt if the water pump pulley is forced up and down. Do not mistake drive belt slippage, which also causes a squealing sound, for water pump failure.

Chevrolet Caprice Water Pump

The Water Pump of Chevrolet Caprice automobiles benefits in circulating coolants from the radiator to the engine with an objective of having the coolant acquire heat produced by the burning of fuel. Common in most Caprice models, the water pump is engaged by a belt from the crankshaft; however, newer models might include electric water pumps. These pumps normally include a shaft with some bearings, a pulley that is belt driven, and an impeller through which the coolant is circulated across the passages of the engine. Some signs that a water pump is on its way out is that the coolant is leaking, the bearings are noisy and the engine gets overly hot. High performance water pumps can be used in high performance engines providing more coolant flow and less power draw as opposed to traditional pump. Electric water pumps are also included as: independent coolant circulation from engine RPM, and another is cooling down racing engines after shutdown.
