2742000900 BEMWQ Water Pump for Mercedes Benz W205 X253 X204 V212 W448 M274

The BEMWQ Water Pump (Part No.: 2742000900) is a vital engine cooling system component designed for Mercedes-Benz vehicles equipped with the M274 1.6L/2.0L turbocharged inline-4 engine. It is fully compatible with chassis models including the W205 (C-Class), V212 (E-Class), X253 (GLC-Class), X204 (GLK-Class), and W448 (V-Class/Vito). This mechanical water pump is driven by the engine's serpentine belt and is responsible for the forced circulation of coolant between the engine block, cylinder heads, and radiator, ensuring the engine operates within the optimal temperature range to prevent overheating and maintain efficiency .

• Precision OEM Fitment:​ Manufactured to match the original equipment specification 2742000900, ensuring exact alignment with mounting points, pulley configuration, and hose connections on the M274 engine for a seamless, direct replacement without modification .

• Efficient Impeller Design:​ Features a precision-engineered impeller (typically using a durable plastic or metal composite) designed to provide optimal coolant flow and pressure, effectively dissipating high thermal loads generated by the turbocharged engine .

• Durable & Corrosion-Resistant Build:​ Constructed with a robust aluminium alloy housing and equipped with high-quality ceramic or carbon mechanical seals that resist degradation from coolant chemicals, ensuring long-term durability against thermal cycling and corrosion .

• Low-Noise Bearing System:​ Incorporates high-quality, precision-ground bearings that ensure smooth, low-friction rotation, minimizing operational noise and vibration while extending the service life of the pump .

• Prevention of Overheating & Costly Engine Damage:​ Ensures continuous and efficient coolant circulation, effectively eliminating the risk of the engine running hot, which protects critical components like the cylinder head and head gasket from warping or failure due to excessive heat .

• Elimination of Coolant Leaks:​ Replaces ageing pumps that often suffer from worn shaft seals or gasket failures (resulting in coolant weeping from the weep hole or housing), restoring a leak-free cooling system and preventing coolant loss .

• Restored Engine Performance & Efficiency:​ By maintaining a stable and optimal engine temperature, it helps ensure efficient fuel combustion, reduces harmful emissions, and keeps engine oil at the right viscosity for peak performance and longevity .

• Cost-Effective Maintenance Solution:​ Offers a dependable and economical alternative to dealership original parts for both corrective repairs (when dealing with a noisy bearing, leak, or failed pump) and preventative maintenance (often recommended around 90,000–120,000 miles), delivering reliable thermal management for the M274 engine .
