Q: How to remove and install a water pump on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: If a failure occurs in the shaft seal on the water pump, a coolant leak can usually be seen coming from that area. Water pumps are equipped with small weep or vent holes that can be checked for leaks using a flashlight. If the water pump shaft bearings fail, there may be a howling sound near the water pump while it's running.
