How to Heat Plugs for a Cold Start
- 1). Plug the heat gun into a socket and turn on the power and the heat to medium. Open the hood and locate all the spark plugs.
- 2). Remove the rubber wires from the ends of the spark plugs. Apply heat to the engine block and the ends of the spark plug using the heat gun.
- 3). Apply the heat in a side to side motion six inches away from the spark plugs and engine block. Do this until the plugs and the engine block are warm to the touch.
