One of the differences of diesel to petrol engines is the plug that ignites the fuel mixture in it. A diesel engine is equipped with a glow plug while a petrol engine has a spark plug. Both plugs are pieced into the engine cylinders of vehicles equipped with both a diesel and petrol engine. Since they almost look the same and used in the cylinder in the same way, it's good news that in diesels, the plug actually glow, hence the name. Much like other auto components, the glow plug also wears out over time. It can easily be installed and even an average garage mechanic can do the task by him or herself. This will only imply removal of the valve cover and other parts on the way to the plug access. The electrical connectors should be disconnected and also the plug from the cylinder. Add the glow reamer into the opening and the new plug can go directly into the hole that is made. Put everything back and the task is complete. Installation is that easy, isn't it?
