Model: (Various brands) Various
Part: Glow plugs

The 1.3 CDTI engine is used in many models from Fiat, Lancia, Opel, and Suzuki, making glow plug wear a common issue. The glow plugs are located at the front of the engine, just in front of the rocker cover. Simply remove the engine cover to locate them. A quick functionality check can be done by disconnecting the connector and gently touching the glow plug with an electric wire connected to the positive terminal of the battery: if a spark occurs, the glow plug is fine. A problem that may arise during replacement is that the glow plug may not unscrew. It is advisable to spray some penetrating oil and let it sit overnight before unscrewing it with an 8 mm socket.
