  Q: What are the methods to check the operation of a water pump while it remains installed on Mazda MX-6?

  A:

  Failure of the water pump may cause overheating and great damages in the engine because of coolant insufficiency to circulate. The working of the water pump may be tested in three ways when it is still on the engine and in case it is discovered to be faulty it must be replaced with a new or refurbished one. When the engine is at normal operating temperature, it will be possible to detect a surge in pressure by squeezing the upper radiator hose in the event the water pump is operational. Water pumps contain weep or vent holes and when the pump seal fails, there will be leakage of small quantities of coolant at the holes; it will be necessary to check the leakage by removing the timing belt lower cover and inspecting with a flashlight under the car. Also, when the water pump shaft bearings become faulty one might hear a squealing noise that comes out at the front of the engine when it is running and this can also be detected by pressing the water pump pulley up and down.
