Specifically designed for 2004-2010 Volkswagen Golf, Jetta, and New Beetle models with TDI Pump Duse engines, this tool safely locks the crankshaft in place during timing belt replacement, preventing any movement that could throw off your timing.

The confidence of knowing your crankshaft is securely locked in place while you're working on the timing components is worth every penny.
