Double Offset Ratchet Wrench, 8 x 12 mm – Glow Plug Installation & Removal
Brief Overview
This specialized double-offset ratchet wrench is engineered specifically for diesel engine glow plug service on Volkswagen, Audi, BMW, and Renault vehicles. The offset design provides critical clearance when accessing glow plugs positioned between the motor unit and diesel injection pump—a location where conventional tools simply cannot fit. The dual 12-point ratcheting heads (8 mm and 12 mm) give you flexibility across multiple engine variants, and the reversible pawl mechanism ensures efficient bi-directional operation. For shops handling European diesel maintenance, this tool is indispensable. Consider pairing it with other precision ratchet wrenches in smaller sizes to cover your complete diesel service range.

Why This Tool Matters
Glow plugs on modern diesel engines are often positioned in confined spaces between the engine block and fuel injection pump. Standard open-end or standard ratchet wrenches lack the geometric clearance to reach these plugs safely. The double-offset design of this wrench solves that problem—it threads through tight engine bays while the ratcheting action delivers the torque needed for secure installation and removal without stripping or cross-threading.
The 12-point head minimizes cam-out risk on glow plug hex profiles, reducing the chance of stripped plugs and costly comebacks. The reversible ratchet mechanism means fewer tool changes during service, improving shop throughput.
