Oil Pressure Control Switch Socket for Mercedes-Benz M651 Diesel Engines

Brief Overview

This is a purpose-built socket for removing and installing the oil pressure control solenoid switch on Mercedes-Benz M651 diesel engines. It's a straightforward, single-task tool that eliminates guesswork and potential damage during this common service procedure across Mercedes' diesel lineup. For shops handling M651 engine maintenance, pairing this socket with specialized diesel engine timing tools ensures you have the right tool for both routine and more involved diesel service work.

Key Features

• Six-Point Engagement Design: Rectangular tabs engage the solenoid switch with precision, preventing slippage and cam-out damage
• Dual Drive Compatibility: Works with both 24mm spanner for hand wrench access or standard 1/2-inch drive socket wrench for better mechanical advantage
• Carbon Steel Construction: Durable, hardened steel body with manganese phosphate coating for corrosion resistance and extended tool life
• OEM-Equivalent Specification: Designed to fit OEM control solenoids A 651 180 01 15 (equivalent to OEM part 651589000900)
• Compact, Single-Purpose Design: Minimalist form factor reduces inventory complexity

Real-World Application

This socket addresses a specific maintenance point on the M651 diesel platform. The oil pressure solenoid switch is accessible on multiple vehicle models but requires a dedicated socket due to its unique geometry. Without this tool, technicians face risk of rounding the switch housing or cross-threading the electrical connector during removal. For independent shops and dealer service departments handling Mercedes diesel vehicles, this is a must-have for routine oil system diagnostics and solenoid replacement.

Why This Socket Matters

Oil pressure solenoid switches on the M651 platform require careful handling. The socket's six-point engagement distributes load evenly, eliminating the risk of stripping or damaging the switch housing—a costly mistake on modern diesel engines. The dual drive compatibility gives technicians options based on workspace constraints, a practical advantage in engine bay work.

For resellers, this socket fills a critical gap in the Mercedes diesel toolkit. It's the kind of specialized accessory that separates a basic socket set from a fully equipped diesel service operation.
