SECTION 2 - OPERATION

Engine Oil Pressure Gauge

The engine oil pressure gauge, 1, is a mechanical gauge that has a capillary tube to the engine to provide oil pressure for the gauge. The gauge has a 0 to 500 kPa (0 to 75 PSI) display on its face. The gauge is tied into the Electronic Instrument Control System to warn the operator that an unusual engine oil pressure reading is present during operation. For further information about the electronic dash module and how it relates to oil pressure, see “Electronic Instrument Control System” later in this section. The gauge also has red (warning) and green (normal operation) segments on the face of the gauge to indicate the operating range. The red (warning) segment, 2, stretches from 0 to 100 kPa (0 to 15 PSI) and indicates the engine is running at a lower than normal oil pressure. The green (normal operation) segment, 3, stretches from 100 to 500 kPa (15 to 75 PSI) and indicates the engine is running within normal oil pressure parameters.

Engine Coolant Temperature Gauge

The engine coolant temperature gauge, 1, is a mechanical gauge that has a capillary tube to the engine to provide a coolant temperature reading for the gauge. The gauge is tied into the Electronic Instrument Control System to warn the operator that an unusual engine coolant temperature reading is present during operation. For further information about the electronic dash module and how it relates to engine coolant temperature, see the “Electronic Instrument Control System” portion of this section. The gauge is numberless with two indicator bands on it to display engine coolant temperature. The green zone, 2, (normal operating temperature) ranges from 54°C to 109°C (130°F to 228°F). The red band, 3, (warning operating temperature) ranges from 109°C to 121°C (228°F TO 250°F).

NOTE: On 2360 and 2425 tractors equipped with electronic engines, the engine coolant temperature gauge is not tied into the module. The system has its own temperature sending unit. See “Electronic Instrument Control System” portion if this manual for more information.
