What is Engine Timing Tools (Locking Kit)?

Each engine family usually needs its own kit. They prevent the cams from moving when the belt is off. Some engines have no timing marks and rely only on the tools. Some kits are rented out by parts suppliers for specific engines.

How it works

Pins fit into holes in the crank, flywheel or cam gears and hold them in the factory-set position.

Why it matters for your car

Wrong timing can bend valves on interference engines. Always follow the exact procedure and torque values for the engine.
