Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Glow Plug System
Engine starting is aided by an electric glow plug system. Glow plugs are small heaters that assist in cold starting. A glow plug is threaded into each cylinder combustion chamber. This system pre-heats each combustion chamber to aid ignition of fuel.
System consists of 4 glow plugs, control switch, timer, and a wiring harness which incorporates 4 fused wires (one for each glow plug) located between wiring harness and glow plug terminal.
The glow plug controller and relay cycle 12 volts to these 6-volt heaters, which causes them to heat rapidly. After engine starts, glow plugs remain on between 4 and 10 seconds during initial starting cycle.
