Quick facts
- Part: Standard Ignition RY1866 diesel glow plug controller
- Fits: 2010-2012 Chevrolet Express 2500 and other vehicles
Hard starting when cold, long cranking or a glow plug light that acts up can mean the controller is failing. Worn glow plugs, a weak battery or damaged wiring can be behind those signs as well, so find the cause before you buy a controller. Each engine needs just one controller.
