Glow PlugGlow plug listed as an aftermarket replacement; contact us to verify fit before ordering for diesel-powered industrial forklifts and compact construction equipment. Glow plugs preheat the combustion chamber so the engine fires cleanly on cold mornings, especially in refrigerated warehouses and outdoor yards. Hard starting, white smoke at startup, or a flashing preheat lamp are the usual signs a glow plug or two has failed. Diesel technicians replace them as a set because survivors are usually close behind.
