Help your diesel start on cold mornings with the Standard Ignition Diesel Glow Plug Relay RY-553, the switch that sends heavy current to the glow plugs when the system commands preheat. It fits many Ford trucks and vans, among them the 1995-1996 Ford F-250, 1990-1997 Ford F-Super Duty and 1990-1996 Ford E-350 Econoline, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
A glow plug relay lets a small control signal switch the high current the glow plugs draw, so the plugs can heat the combustion chambers for cold starting. If a failed relay is the cause of hard cold starts, long cranking or heavy smoke right after start-up, this unit replaces it.
