| 123-6700 | Infrared Thermometer | 1 |
When the engine runs at low idle, the temperature of an exhaust manifold port can indicate the condition of a unit injector:
A low temperature indicates that no fuel is flowing to the cylinder. An inoperative unit injector pump could cause this low temperature.
A very high temperature can indicate that too much fuel is flowing to the cylinder. A malfunctioning unit injector could cause this very high temperature.
Use the 123-6700 Infrared Thermometer to check this exhaust temperature. You can find operating instructions and maintenance instructions inside the Operator's Manual, NEHS0630, "123-6700 Infrared Thermometer II with Laser Sighting".
