Left Side
REMOVAL PROCEDURE
1. Disconnect the negative battery cable(s). Refer to Battery Disconnect Caution. See: Computers and Control Systems/Service
Precautions/Vehicle Damage Warnings
2. Use J 39083 glow plug connector remover and installer in order to disconnect the glow plug lead wires.
CAUTION: Serious engine damage will occur if the damaged glow plug is not retrieved from the cylinder. There are two methods that are used
in order to remove glow plugs with blistered or swollen heater coil sheaths.
Method I
1. Remove the injector nozzle from the failed glow plug cylinder.
2. Place a shop towel in the precup chamber in order to capture the glow plug tip when it breaks off from the glow plug shell upon removal (this will
keep the tip from dropping into the cylinder).
3. Use a pair of needle nose pliers (or other griping device) in order to grasp the tip and remove it from the precup chamber.
4. Remove the shop towel and reinstall the injector nozzle.
Method II
If the glow plug tip has already broken off the glow plug and it is not retrievable from the precup chamber, then the cylinder head must be removed so
that the tip can be retrieved from the piston cylinder. Refer to cylinder head removal.
3. Remove the glow plugs from cylinders 1, 3, 5 and 7.
INSTALLATION PROCEDURE
1. Install the glow plugs.
Tighten
^
Tighten the glow plugs to 17 Nm (13 lb. ft).
2. Connect the lead wires to the glow plugs.
