Detailed Description

VAICO VAICO V30-50002 is an engine water pump for Belts and Cooling applications, engineered as a mechanical unit with a metal impeller and integrated housing. This configuration supports coolant flow through the engine cooling circuit and is listed with OE reference PA0145. It is a direct-fit option for Mercedes-Benz 190E, 300E, 300TE, 300SE, and 300SEL models in the 1990-1993 range, making it a relevant choice for Mercedes-Benz cooling system service where the original pump assembly is being replaced.

This part cross-references Airtex AW9202 and Gates 20621 for the same application.

What It Is Used For

• Restoring coolant circulation in a worn or leaking cooling system
• Replacing a pump with bearing noise or impeller wear
• Addressing coolant loss from a failing pump seal
• Correcting overheating concerns tied to reduced coolant flow
• Servicing Mercedes-Benz 190E, 300E, 300TE, 300SE, or 300SEL cooling systems

Installation Notes and Tips

Verify OE reference PA0145 and confirm the housing-style pump matches the removed unit before installation. Inspect the mating surfaces, coolant passages, and drive components during service, and replace degraded coolant as part of the repair. Follow the vehicle service procedure for torque and bleeding the cooling system after installation.

Quality Assurance

VAICO supplies aftermarket cooling components with OE-reference alignment for select Mercedes-Benz applications. The V30-50002 is specified with a metal impeller, housing, and seal for a service-ready replacement configuration.
