The following are general instructions for the removal and installation of glow plugs. For more detailed
instructions pertaining
to your specific vehicle, consult an appropriate repair manual. Follow all safety precautions.
Technical Tips:
Tip 1.
Be careful not to break or fracture the glow plug in the head. If glow plug breaks or fractures in the head you
may have
to push the pieces into the combustion chamber and remove the pieces through the injector hole using
a magnet or claw tool. In some engines the heads must have to be taken out to remove the pieces.
Make sure not do damage the threads.
Tip 2.
Sometimes glow plugs go bad because glow plug timer system is not working correctly. If glow plugs stay on too
long they
could burn out. Make sure your timer system is working correctly before you install new glow plugs.
- Remove the valve cover (Ford) if required.
- Remove the parts needed to gain access to the glow plugs.
- Disconnect the electrical connector/s.
- Using the correct deep socket or combination wrench, remove the glow plug from the cylinder head.
Turn a 1/4-1/2 of a turn and spray penetrating oil lubricant, turn the wrench or socket back
and forth until it feels loose, keep going until is out.
- Screw the glow plug reamer into the glow plug opening all the way in then out to remove carbon deposits.
- Install the new glow plug.
- Reconnect the connector to the glow plug terminal.
- Reinstall any parts removed for glow plug access.
