Saturn LS Water Pump

The Water Pump is used in Saturn LS vehicles to circulate coolant taken from the radiator and passed over the top of the engine to receive and release heat produced during combustion. It is common to find he LS vehicles featuring a belt driven water pump with an impeller that pumps the coolant through the passages of the engine. The old type of water pump was of cast iron while the new pumps are generally of aluminum casting but much more efficient. Signs that show that water pump is about to fail are therefore leaks on the coolant, noises originating from the bearings, and increase in the temperature of the engine. High Performance water pumps for high performance engines, crankshafts and bearings include water pump impellers and internal passages for higher coolant flow and lower parasitic power loss. Other special purpose coolants include electric water pumps as well which more efficient and offers better control of water cooling in case a project is small and requires intricate spacing.

Each OEM Saturn LS Water Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Saturn LS Water Pump Parts Questions & Experts Answers

  • Q: What are the signs and consequences of a failure in the water pump on Saturn LS?
    A: A failure in the water pump can lead to serious engine damage due to overheating. If the pump seal fails, coolant will leak either from the engine front cover in four-cylinder models or from the engine timing belt cover in V6 models. It is important to use a flashlight to locate the vent hole on the water pump and check for any leaks. When the engine is off, shaft wear can be felt by rocking the water pump pulley up and down. However, it is crucial not to mistake drive belt slippage, which causes a squealing sound, for water pump bearing failure. A quick check to assess water pump performance is to turn on the heater. If the pump is failing, it may not be able to efficiently circulate hot water all the way to the Heater Core as it should.
