In this video, we can see where the glow plugs are located in an Opel Astra 1.9 CDTI and how to proceed if you need to replace them, a simple operation that requires good manual skills. They are located at the top of the engine and are easily identifiable by their connectors.

To remove them, first ensure the engine is completely cold, then remove the plastic cover, identify the four indicated cables, and disconnect them. Next, take the first glow plug with the appropriate spanner, gently unscrew it, and repeat the process for the remaining three glow plugs.

If possible, tighten the replacements using a torque wrench.
