The Importance of the 7.3 Glow Plug Relay

As a proud owner of a 1999 Ford 7.3 Powerstroke diesel engine, I can attest to the crucial role that the glow plug relay plays in starting my vehicle. The glow plug relay is an essential component of the engine’s pre-heating system, which is necessary for cold starts. Without it, starting the engine in colder temperatures would be nearly impossible.

One of the main reasons why the 7.3 glow plug relay is necessary is because diesel engines rely on compression and heat to ignite the fuel, unlike gasoline engines that use a spark. This means that in colder temperatures, when the air in the cylinders is denser, there needs to be an extra boost of heat to aid in combustion. This is where the glow plug relay comes into play.

The glow plug relay works by sending an electrical current to each individual glow plug in the engine, which then heats up and helps to ignite the fuel during start-up. Without this extra heat, there would not be enough energy for combustion to occur, resulting in a failed start or rough running engine. This not only causes frustration but can also potentially cause damage to other components of the engine.
