Mercedes-Benz B-Class W245 M266 Aircon Pump Compressor | 2005–2011 | B180 B200 AC Compressor Spares

Description

Restore ice-cold climate control, efficient windshield defogging, and premium cabin comfort to your hatchback with this premium Mercedes-Benz W245 Aircon Pump Compressor (AC Compressor Assembly). Specifically sourced and verified for the first-generation B-Class (W245 platform) equipped with the M266 4-cylinder petrol engine (including popular models like the B150, B170, B180, and B200 produced between 2005 and 2011), this mechanical pump is the definitive solution for an air conditioning system that blows warm air, makes loud rattling noises when turned on, or suffers from a seized magnetic clutch.

The Aircon Pump / Compressor is the heart of your vehicle’s climate control loop, tasked with pressurizing and circulating R134a refrigerant through the cabin’s cooling system. Because the M266 engine features a unique sloped placement under Mercedes-Benz’s specialized sandwich-floor safety chassis, the accessory belt routing and spacing are compact and highly precise. Over time, internal piston seals wear out, causing a loss of system pressure, or the internal oil degrades, leading to mechanical friction failure. If the compressor clutch or control valve fails, the pump will not engage, leaving your luxury cabin hot and uncomfortable during intense South African summer days. Replacing the faulty pump restores rapid cabin cooling and smooth pulley rotation.

Manufactured with a high-strength aluminum alloy casing to maximize heat dissipation and reduce front-axle weight, this aircon compressor features a precision-machined multi-groove poly-V pulley wheel designed to line up perfectly with the original M266 belt line. It includes the integrated electronic control regulating valve and factory mounting brackets for a direct, trouble-free bolt-on installation inside the tight engine bay compartment. Trust TP German Auto Spares for fully verified, high-performance climate control components and engine accessories that keep your Mercedes-Benz driving beautifully.
