Bosch Intercooler Water Pumps

Bosch offers intercooler water pumps for a variety of applications, including many Mercedes-Benz cars and trucks from the early 2000s and up. A faulty water pump is a common source of power loss on Mercedes supercharged motors. These upgraded 100 percent plug-and-play replacements exceed OEM standards and are used on all contemporary AMG vehicles. Select the pump recommended for your ride. All water pumps are tested to ensure proper functionality. Torque testing is performed to verify the proper impeller-shaft mating—and can also detect loose impeller-shaft press fits. The 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.
