AIR CLEANER GP 3872616 - Caterpillar

Jacket Water Coolant Temperature - This gauge indicates the temperature of the engine coolant at the outlet for the jacket water. The temperature may vary according to the load. The temperature should never be allowed to exceed the boiling temperature of the pressurized cooling system. The jacket water coolant temperature is regulated to a temperature of 90 °C (194 °F) at the inlet for the jacket water.If the engine is operating above the normal temperature range, perform the following procedure:
Reduce the load and/or the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load and/or the rpm.
Inlet Manifold Air Temperature - This gauge indicates the inlet manifold air temperature after the aftercooler. As the inlet air increases in temperature the following conditions occur: expansion of the air, less oxygen in the cylinders and less power. If the temperature of the inlet air is too high during full speed and load operation, the engine may consume excessive fuel.
Inlet Manifold Air Pressure - This gauge indicates the air pressure (turbocharger boost pressure) in the air inlet manifold after the aftercooler. The pressure depends on the engine rating, the load, and the operating conditions. To establish the normal inlet manifold air pressure, compare the data from the gauge to the data from the engine commissioning and look for trends.
Air Restriction - This gauge indicates the difference in air pressure between the inlet side and the engine side of the air filter element. The air restriction is measured at the air inlet to the turbocharger. As the air filter element becomes plugged, the difference in pressure between the two sides of the air cleaner element will increase. For optimum engine performance, clean the elements or replace the elements when the air restriction reaches 2.5 kPa (10 inches of H2O). Maximum air restriction is 3.7 kPa (15 inches of H2O).
Turbocharger Exhaust Inlet Temperature - This gauge indicates the temperature of the exhaust gas at the inlet of the turbocharger.
Exhaust Port Temperature - This gauge indicates the temperature of the exhaust gas from each individual cylinder. The temperature is measured at the exhaust port of each cylinder head. The exhaust temperature will vary slightly between the cylinders. Individual cylinder exhaust temperatures should not vary by more than 50 °C (122 °F) from the average of all of the cylinder exhaust temperatures.
Tachometer - This gauge indicates the engine rpm.
To help prevent engine damage, never exceed the high idle rpm. An overspeed can result in serious damage to the engine. The engine can be operated at high idle without damage, but the engine should never be allowed to exceed the high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Engine Hours - This meter indicates the total number of clock hours of operation for the engine.
Fuel Pressure - This gauge indicates the fuel pressure to the engine from the fuel filter. The
