Product Details

Gates water pumps are manufactured with premium alloy materials and are tested for seal and bearing function as well as leakage at both the casting and assembled pump stages. This Gates 41236 water pump is built for BMW models that use a reverse-rotation, accessory-belt-driven cooling setup, making it a direct replacement choice for service work on the BMW 230i, BMW X3, BMW 530i, and related applications. This part cross-references Carlson 41236 for the same application.

What It Helps Address

• Coolant circulation problems caused by a worn pump
• Leakage at the water pump housing or seal area
• Noisy or rough pump bearing operation
• Overheating from reduced coolant flow
• Service replacement on BMW cooling systems with reverse-rotation drive

Installation Notes

Verify the vehicle uses an accessory-belt-driven, reverse-rotation pump before installation. Confirm whether the application is listed as W/O housing, since this pump is supplied without a thermostat housing or back housing. Check pulley alignment, belt condition, and sealing surfaces during installation.

Quality Assurance

Gates tests each new water pump for seal and bearing function and performs leakage checks on both the casting and the assembled unit. The result is an OE-quality fit for the listed BMW applications, including 2019-2025 BMW 330i, 2020-2025 BMW X4, and 2021-2024 BMW 430i fitments.
