Product Overview
This is not a cylinder glow plug. It mounts in the intake manifold and creates a small flame to warm incoming air when a Perkins diesel struggles in cold weather.
For the repair to hold up, the part still has to match the original application. Replace it when testing shows the element or fuel valve inside the thermostart has failed. A no-flame condition can also come from missing voltage, an empty supply line, or a blocked feed.
