Glow Plug

The first step for Spark Plug replacement begins with turning the boot of the Spark Plug wire a 1/2 turn counterclockwise before removal and pulling on the boot itself rather than the cable or using a specialized tool. After turning the Spark Plug 1 or 2 rotations you should brush away dust in the area or use air blast methods before removing the Spark Plug. Multiple plugs need separate trays where the correct cylinder number marks each container. The correct placement of the Spark Plug washer must be confirmed during installation while you should check and adjust the Spark Plug gap to 1.524 mm (0.060 in) when needed. Fitting the Spark Plug into the specified cylinder requires hand-tightening to 15 n.m (11 lb ft) for used heads while new aluminum heads require 20 n.m (15 lb ft) torque and new iron heads need 30 n.m (22 lb ft).

You need to start by taking off the Spark Plug wire followed by turning the Spark Plug only 1 or 2 turns open. A brush or compressed air canister can blow away dirt from the Spark Plug area before extraction. It is essential to place each removed plug in a dedicated tray which corresponds to the cylinder number. When inserting a Spark Plug always begin by setting the washer correctly while checking the gap using a suitable tool before making adjustments to 1.016 mm (0.040 in). Begin hand-tightening the Spark Plug in the designated cylinder then secure it to 15 n.m (11 lb ft) for used heads but use 20 n.m (15 lb ft) for new heads. Position the Spark Plug wire as the last step of installation.

First step starts by taking off the Spark Plug wire which leads to the subsequent step of loosening the Spark Plug between 1 to 2 turns. Before uninstallation of the Spark Plug use either compressed air or a clean brush to clean away dust from its surrounding area. When dealing with multiple plug removals then set each component into trays which display cylinder identification numbers. The correct placement of the Spark Plug washer must be followed by checking the Spark Plug gap before adjusting it to 1.016 mm (0.040 in). The Spark Plug installation begins with hand starting the plug in its designated cylinder while applying 15 n.m torque (11 lb ft) for used heads or 20 n.m torque (15 lb ft) for new heads. The procedure concludes by placing the Spark Plug wire.

The first step to Spark Plug replacement begins with removing the wire by turning the boot half a turn before gently pulling the boot from the Spark Plug to break the connection. Before taking out the Spark Plug you should vacuum or brush off all soil in the area. Each new Spark Plug requires a dedicated tray which should bear the labeling for its destination cylinder number. During Spark Plug installation the washer needs proper positioning followed by a suitable check of the plug gap with necessary adjustments made. Begin with hand-starting the Spark Plug into its designated cylinder slot before fastening it to 15 n.m (11 lb ft). Reinstall the Spark Plug wire before checking the seating of each boot by gently pushing sideways. Replace any loose boot when necessary.

The first step for Spark Plug replacement begins with turning the boot of the Spark Plug wire a 1/2 turn counterclockwise before removal and pulling on the boot itself rather than the cable or using a specialized tool.

The starting point of replacing a Spark Plug includes disconnecting the Spark Plug wire followed by rotating the Spark Plug one or two turns counterclockwise. Before removing the Spark Plug take time to brush away or blow out excess dirt from its base. Place all spark plugs to be changed in separate trays where each one bears the identifier of its assigned cylinder. Placement of the Spark Plug washer should be correct during installation and measurements for the Spark Plug gap should be made to adjust it to 1.524 mm (0.060 in). Slight hand motion should start the Spark Plug in each cylinder before proper torque reaches 20 n.m (15 lb ft) for used heads or 30 n.m (22 lb ft) for new heads. Reinstall the Spark Plug wire as the last step.

Correctly position the spark plug washer and inspect the spark plug gap, adjusting it as needed to 1.524 mm (0.060 in).

For new aluminum heads, tighten to 20 N.m (15 lb ft).

Tighten the spark plugs for used heads to 15 Nm (11 lb ft).

Brush or air blast away any dirt from around the spark plugs.

Brush or air blast away any dirt from around it before removing the spark plug.

Place each spark plug in a tray marked with the corresponding cylinder number.

Loosen the spark plug 1 or 2 turns, then brush or air blast away any dirt from around it before removing the spark plug.

First, remove the spark plug wires and loosen each spark plug by 1 or 2 turns.

Tighten it to 15 Nm (11 lb ft).

Brush or air blast away any dirt around it.
