Checking glow plugs
1. Disconnect the glow plug wires.
2. Measure the resistance between the glow plug lead and the body ground. If the measured value is not correct, replace the glow plug with a new one.
Note: Nominal glow plug resistance: 1.0 ohm (at 20°C).
Removal and installation of glow plugs
1. Electrical wiring for glow plugs.
2. Glow plugs.
Attention. Do not use a glow plug that has been dropped from a height of more than 10 cm, even if there is no visible damage and the resistance of the plug is correct.
1. Disconnect the negative battery terminal.
2. Remove the engine cover.
3. Remove the components shown in the illustration and set aside.
4. Remove the intake manifold insulator.
5. Disconnect the wire end from the glow plug as shown.
6. Loosen the glow plug with a wrench a few turns, then unscrew the glow plug by hand.
Attention. Soot deposited on the glow plug can damage the glow plug and the engine. Before installing the glow plug, the soot must be removed from the glow plug and the mounting hole.
7. Limit drill (∅ 5.0-5.2 mm) or perk (∅ 5.2-5.4 mm) at a distance of 119-121 mm from the edge with electrical tape.
8. Turning the drill by hand, remove carbon deposits from the glow plug mounting hole.
9. Repeat descaling with perk.
10. Screw in the glow plug by hand and finally tighten with a wrench.
11. Further installation is carried out in the reverse order of removal.
