SECTION 10M. GLOW PLUGS
GLOW PLUG TESTING
The glow plugs warm the engine precombustion cham-
ber and help the engine to start during cold weather.
The glow plugs need to operate in unison to warm the
engine for quicker starts. The glow plugs are mounted
in the cylinder and connected with a metal strip con-
nector.
The glow plugs can be tested using the following pro-
cedures.
1. Shut down the engine and remove the ignition
key. Allow the engine to cool completely.
2. Remove the wiring harness connector and metal
connector strip from the glow plugs.
3. Set the multimeter to 200
Ω
scale.
4. Place one test lead to the glow plug connector
stud and the other test lead to the base of the
glow plug or a good ground (Figure 10M-1).
The multimeter should indicate approximately
1.4
Ω
. If the reading is infinity or 0
Ω
, replace the
glow plug.
