Installing the Warning Decal(s)
Two 8T2930 decals are included in the group:
Example of the 8T2930 decal installed close to the engine's 9L6531 Engine Information Plate.* Install one in a VISIBLE location in vehicle cab ... and* Install one in a VISIBLE location in engine compartment or on engine.Operating the Intake Manifold Heater
This portion of the instruction will explain the operation of the intakemanifold heater and a basic explanation of how it works.A few moments spent learning the sequential steps required to engage the system, and a reasonable knowledge of the components functions during cranking, will allow the operator to start the engine in a minimum amount of time.Procedures to Start the Engine
Switch on (RUN position) the main key operated switch:* The indicator light MUST light up and stay on for the duration of heating process.* This will start the (40 - 60 seconds) heater plug preheat mode. The heater plug will start to heat as soon as the switch is activated (RUN position). The heater plug will soon be too HOT to touch.The preheating process is voltage dependent, refer to the Corrective Action column in the Troubleshooting chart.* The preheating process will last 40 - 60 seconds (depending on the voltage).* Upon completion of the preheating process the pilot lamp will go out.* The engine can now be started.Start the Engine
The engine must be started:As soon as the engine starts:* The indicator light will light up again for the entire duration of the inlet manifold heating process.* Not later than 30 8 seconds AFTER the indicator light goes out ... and* The alternator MUST reach charging speed ... or* The oil pressure switch MUST close.If these two requirements are NOT met:* The intake manifold heating system will be switched OFF automatically.This happens when the alternator does not provide a signal to the D+ terminal of the ECU.If this occurs:To restart the engine the main key operated switch must now be:* Switched OFF for several seconds before attempting to start the engine.When the main switch is switched on (RUN position) again:* The pilot lamp will light up to indicate the start of the preheating process.The engine can be started after:* The pilot light goes out.After Engine Start
After the engine is started:* The engine speed must NOT be allowed to exceed low idle rpm for the duration of the intake manifold heating process.The heating cycle is completed as soon as:* The indicator light goes out.The duration of the intake manifold heating process is up to 6 minutes and is controlled automatically by the Electronic Control Unit (ECU).Intake Manifold Heater System Functional Check
Fuel Lines
Inspect all fuel supply/return lines, connections, and screw type fittings for fuel leakage.Replace/repair/tighten if required.Checking the System At Ambient Temperature
The system can be checked for correct operation at any temperature by:* Disconnecting the temperature sensor ... and* Performing the normal (cold start) engine starting procedures.The system can now be checked for correct operation even when the engine is at normal operating temperature.Refer to Operating the Intake Manifold Heater
