The spark plugs are located on the top of the engine, below the plastic engine cover. Open the engine cover and look near the front of the engine, close to the bulkhead that separates the engine bay from the passenger compartment. You should see black rubber covers and/or wires. Below these are spark plugs.
Some models of Vauxhall Corsa may also have a coil pack. The coil pack provides the spark for the spark plugs. It is located on top of the spark plugs and is easily identifiable as it has multiple electrical connectors.
On Diesel engines
Vauxhall Corsa diesel engines do not have spark plugs. Instead, they use glow plugs which heat up the air in the cylinder to help the fuel ignite. The glow plugs are located in the cylinder head.
