to preheat the air
The glow plug is the diesel version of a spark plug. There are 4 glow plugs (1 for each cyl.) located usually near the injector on top of the cylinder head.AnswerThe glow plug is NOT the diesel version of a spark plug, they both do different jobs. The glow plug is there to aid starting when the engine is cold. The spark plug is there to provide the spark for combustion to take place in a petrol/gasoline engine.
only if you have a diesel engine.
The purpose of a glow plug in a compression-ignition (CI) engine, commonly found in diesel engines, is to preheat the combustion chamber to facilitate easier starting, especially in cold conditions. When activated, the glow plug heats up and helps ignite the air-fuel mixture by raising the temperature of the incoming air, which is crucial for achieving proper combustion in diesel engines. This aids in reducing engine starting difficulties and emissions during cold starts.
A diesel glow plug solenoid typically connects to the vehicle's battery for power, receiving a direct electrical supply to operate. It is usually activated by the ignition switch or a relay, allowing it to control the flow of electricity to the glow plugs when starting the engine. This ensures that the glow plugs heat up properly to aid in cold starting the diesel engine.
A spark plug actually sparks, and is generally only used in a gasoline engine. A glow plug just gets warm (glows), and is used in some diesel engines.The difference between spark plugs and glow plugs is that a spark plug delivers current from an ignition system to the combustion chamber while a glow plug is a heating device that aids starting diesel engines.A spark plug actually sparks, and is generally only used in a gasoline engine.

Most diesel engines will have a 'glow' plug that gives of enough heat to help get the engine started. The heat generated from the first few revolutions together with the compression from the piston is enough to ensure the engine keeps running. Some modern diesel engines no longer require a glow plug.
Glow is probably for "glow plug" which is a diesel engine application. If your vehicle isn't diesel, it had that option as an engine, so that fuse would be found empty in your vehicle. If your vehicle is a diesel, a blown fuse here would lead to a "hard to start"or "no start" issue.
Wait until the light turns off then start the car. Diesel engine?
On the engine compartment side immediately next to the battery
A glow plug problem can be spotted by the vehicle having trouble starting the engine. The indicator light in the for a glow plug can indicate a bad disconnected or corroded glow plug, or even a bad temperature sensor. If when you first start the engine there is a misfiring until the engine warms up, it is a good chance a glow plug problem. Usually misfiring will cease after the engine has been running about ten minutes. One of the last systems of a bad glow plug is you see white exhaust when starting the engine. Diesel is let into the combustion chamber to start the engine. A bad or even disconnected glow plug will allow diesel to leak from the chamber into the exhaust. The fuel is then ignited in the exhaust pipe and produces a white smoke. Once the engine again warms up the white smoke will stop.
It is broken. Continuous glow plugs are for emergency generators in freezing climates. On all other engines, the glow plug is not continuous. It would serve no purpose. The continuous glow plug does not offer any benefit once the engine is running.
Do you have an old diesel or a new one? If you have an old diesel engine, you turn the key to the "run" position and look for the glow plug light. Glow plugs heat the cylinders, and when the engine is warm the light goes out, you turn the key and the engine starts. On a new diesel, you turn the key and it starts.
