Water is as vital to the life of your vehicle as it is to your own. The water that courses through the pump and various tubes keeps your engine cool and performs other crucial functions. So when your water pump starts misbehaving, you need to jump right on it and get it repaired or replaced (usually replaced).
Symptoms of an ailing water pump
If there is water on your garage floor or driveway after you’ve parked it overnight, you may have a leaking water pump. (Note: if the liquid is green your engine is leaking coolant. If the liquid is red, you have a transmission leak.)
Look for leaks around the gasket of the water pump. See moisture? Your pump is losing water.
If your water pump pulley is loose, have it inspected to see if it should be replaced.
With the hood up, listen for a faint or more pronounced grinding noise. If a water pump bearing is failing, you’ll hear it distinctly.
Watch the thermostat warning light on your instrument panel. If your water pump is losing water, the warning light should come on (providing your instrument panel is working properly)
Watch to see if the low coolant light comes on. If it does, your coolant reservoir may be leaking; there may be a leak in the coolant system; or you may need to replace the water pump.
Water pumps will typically start leaking coolant from the weep hole on the pump. The weep hole is at the bottom of the pump shaft which is designed to allow coolant to leak past it when the bushing that the shaft rides on begins to wear down. This leak lets you know know that the water pump is worn to the point of needing replacement.
If you notice any of these troubling signs or symptoms, it’s time to have your water pump checked out, so give us a call.
