Only diesel engines have glow plugs. Instead of igniting the air/fuel mixture in the cylinders, this is burned. Consequently no spark is needed. Instead, the top of the glow plugs glow thereby increasing the temperature of the air/fuel mixture until the latter starts burning. Glow plugs therefore need to reach a temperature of 800°C though. Like spark plugs, glow plugs are powered by HT leads.
In general, the glow plugs of your Fiat will need replacing every 50 000 miles. To ensure you order the right plugs for your Fiat, we recommend you select the model and engine type of your car into the search engine.
