Glow Plug Replacement Without CTF

The glow plugs can be tested in 2 ways:

•

Take an amperage draw test with an inductive pick-up lead at each glow plug. The rated amp draw should be 3.0-4.5 amps per glow plug. Or install the inductive current clamp around the glow plug power supply wire. Take the systems current draw reading and divide the reading by the number of glow plugs in the system.

•	A continuity test can also be made with an ohmmeter between the glow plug lead and ground, with the buss bars removed. If no continuity exists, the glow plug will not heat and should be replaced.

1. Remove the air cleaner layer. Refer to Air Cleaner Replacement .
2. If required, remove the engine cover. Refer to Engine Cover Replacement .




Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

3. Disconnect the negative battery cables.
4. Disconnect the glow plug power supply wire.
5. Disconnect the glow plug buss bar.

7. Remove the glow plugs from the cylinder head.

Notice: Refer to Component Fastener Tightening Notice in the Preface section.
