This water pump is 100% new and designed to meet exact original equipment specifications. All water pumps are also 100% tested to ensure proper functionality.The torque testing is performed to verify the proper impeller- shaft mating. Torque testing can detect loose impeller- shaft press fits.Water pumps are vacuum leak tested to ensure proper sealing. This test can detect leaks throughout the housing， seals， tube binding and plug leakage. Bosch utilizes OE mating parts and accessories to verify proper fitment in situations where the isolator grommet and bracket can be re-used. Retain them when removing the previously installed pump.
