The Water Pump in your GMC Savana sends coolant through the block and radiator to prevent the engine from overheating. On major models, the Water Pump is belt driven from the crankshaft. An impeller spins, drawing coolant from the lower radiator hose and pumps it into engine internals. More recent models also feature electric Water Pump arrangements, allowing for a decoupled mechanical Water Pump to deliver smoother water flow at low rpm, with a small fuel economy benefit. For both mechanical and electric design Water Pumps, the base-runner pump must be in an aluminum housing. The shaft is supported by bearings, which must be sealed tight to exclude the bearing from fluid. Inside the bearing housing is a special-shaped impeller. It forces coolant to the thermostat. From there, it goes back to the radiator to shed heat. The earlier designs using cast iron were heavier, but they perform the same basic task, so the main difference is weight and corrosion resistance. The coolant that comes through the pump's weep hole when it ages, grinding noises made by the pump, or climbing temperature gauges warn Savana owners of a failure in the heart of the cooling circuit. Prompt replacement enables full circulation of the coolant and prevents the powerful GMC engine from warping and cracking due to excessive heat. Overall, the dependable Water Pump remains a small but vital part that lets every GMC Savana cruise smoothly without fear of overheating.
