Timing Tool Kit for Vauxhall/Opel 1.2 Petrol LIH 2019+

A timing tool kit for Vauxhall and Opel 1.2 petrol LIH engines from 2019 onwards, used when carrying out accurate engine timing and related assembly work. It covers Astra K applications and the F12SHL, F12SHT and F12SHR engine codes, with the dedicated tools needed where proper locking and adjustment matter.

Used for workshop servicing, engine repair and timing belt work on later 1.2 petrol models, this kit helps when setting camshaft timing and refitting related components correctly. It suits mechanics and experienced repairers working on Vauxhall or Opel vehicles where access around the camshaft area can be restricted, and where using the correct engine timing tools helps avoid guesswork during strip-down and reassembly.

The included parts cover more than a basic timing job, with tools for camshaft adjustment, flywheel fixation and front crankshaft sealing ring installation. A special camshaft turning key is included for use in tighter engine bays, along with locking pins for the timing chain tensioner and auxiliary drive belt tensioner. That makes it useful when the lower timing belt cover and crankshaft seal also need to be installed as part of the same job. For regular engine work on these LIH units, having the correct model-specific tools close to hand helps keep the process straightforward and accurate.
