Nissens 833795 Engine Auxiliary Water Pump - Intercooler, To Radiator or To Turbocharger

Engine Auxiliary Water Pump Overview

This Nissens engine auxiliary water pump is an electric replacement built for BMW cooling-system applications that route coolant to the radiator, turbocharger, or intercooler. Part number 833795 is engineered for proper pumping efficiency, electrical compatibility, and stable operation in demanding thermal conditions.

Key Features

• Electric 12-volt operation for controlled coolant circulation.
• Plastic housing construction for lightweight packaging.
• Oval connector shape with male terminals for electrical connection.
• No pulley, gasket, seal, or mounting bracket included.
• Fully tested for pumping efficiency and fit.
• Part number 833795 for BMW cooling-system service.

Detailed Description

Nissens designs this auxiliary water pump to support coolant flow in BMW applications where the pump is used to manage heat around the radiator, turbocharger, or intercooler. The electric design helps maintain circulation when the engine cooling strategy requires an auxiliary pump rather than a belt-driven unit. Part number 833795 is a direct-fit style replacement for multiple BMW 230i, 330i, 430i, and related models listed in the fitment data.

The pump uses plastic construction and an oval electrical connector with male terminals. Nissens states that its electric water pumps are built from high-rated raw materials and tested for pumping efficiency, fit, and electrical compatibility. This part cross-references BMW 11518637953 for the same application.

What It Is Used For

• Restoring coolant circulation when the auxiliary pump is no longer moving fluid correctly.
• Addressing overheating concerns tied to reduced pump output.
• Replacing a pump with electrical connection or compatibility issues.
• Correcting cooling-system performance problems in turbocharged or intercooler circuits.
• Servicing BMW cooling components with the correct auxiliary pump design.

Installation Notes

Verify the connector shape, terminal style, and 12-volt electrical specification before installation. Confirm the application path shown in the fitment data, since this part is used in radiator, turbocharger, and intercooler cooling circuits depending on the vehicle. No pulley, gasket, seal, or mounting bracket is included, so reuse or source any required related components separately.

Quality Assurance

Nissens tests this electric water pump for pumping efficiency, fit, and electrical compatibility. The brand also specifies high-rated raw materials to help protect against overheating, reduce vibration, and extend service life.
