High-Efficiency Cooling
Variable Speed Control: Adjusts coolant flow based on engine load, ambient temperature, and driving conditions.
Turbocharger Protection: Prevents heat soak in high-performance AMG® and BiTurbo engines.
Durability
Ceramic Bearings: Resists wear in extreme temperatures (-40°F to 302°F).
Leak-Proof Design: Reinforced polymer housing and laser-welded seals prevent coolant leaks.
Energy Efficiency
Reduces engine load by eliminating belt-driven operation, improving fuel economy by up to 5% in hybrid models (e.g., Mercedes C300 Hybrid).
Diagnostic Readiness
Compatible with Mercedes STAR Diagnosis for troubleshooting error codes (e.g., P26100 – Coolant Pump "B" Performance).
Compatible Mercedes Models
Sedans: C-Class (W205), E-Class (W213), S-Class (W222).
SUVs: GLC (X253), GLE (W167), GLS (X167).

Symptoms of a Failing Electric Water Pump
Replace the pump immediately if you notice:
Overheating Warnings: Dashboard alerts or limp mode activation.
Coolant Leaks: Puddles under the front axle or low coolant reservoir levels.
Unusual Noises: Grinding or whining from the pump assembly.
Fault Codes: P261B (Coolant Pump "A" Stall) or P2681 (Coolant Pump Control Circuit).
Installation Guide
Coolant Drain: Use Mercedes-approved coolant (e.g., G40) and drain via the radiator petcock.
Remove Old Pump:
Disconnect the electrical connector and coolant hoses.
Unbolt the pump (T30 Torx bit, 10–12 Nm torque).
Install New Pump (A2642000301/A2642000100):
Align the gasket and secure bolts to spec.
Refill coolant and bleed air using the factory bleed procedure.
Coding: Program the pump via STAR Diagnosis to reset adaptation values.
Note: Use only Mercedes-approved coolant to avoid seal degradation.
