Common Cooling Issues It Can Address

• Coolant circulation loss from a worn or failing water pump
• Engine overheating caused by reduced coolant movement
• Coolant seepage at the pump sealing surface
• Noisy operation from a deteriorated pump assembly
• Cooling system service on BMW 325Ci, 330i, 525i, and related models

Installation Notes and Tips

Confirm the vehicle application before installation and compare the original pump to the GMB 115-2090IM. Inspect the mating surface, replace worn coolant system components as needed, and verify that the pre-installed O-ring seats correctly during assembly. Because gaskets are not included and no pulley is supplied, reuse or replacement decisions should be made based on the vehicle’s existing hardware and service condition.
