64 - FORM NO. 56043093 / Captor™ 4300, 4800, 5400ENGINE SYSTEMrevised 7/08MISCELLANEOUS ENGINE SYSTEM INFORMATIONAdditional Engine Troubleshooting SymptomEngine OverheatingUse the checklist below as a guide, to thoroughly check the engine cooling system.• Check coolant level in overflow tank and radiator.• Inspect and clean radiator and hydraulic oil cooler.• Check for proper operations of the hydraulic driven engine cooling fan (RPM’s).• Check to see that the engine thermostat opens.• Check for proper operation of water pump.• Check engine crankcase oil level.Over Temperature Protection: The GM 1.6L engine will set a diagnostic test code (DTC 116) after 5 sec. at temperatures over 215 °F and apower derate level one will be enforced. This engine fault will limit the maximum throttle position to 50%. With further overheating the enginewill set a code (DTC 217) after 10-15 sec. at temperatures over 225 °F and the engine will then shut down.Loss of Oil Pressure Protection: Engine shutdown if oil pressure is only 3-7 PSI.Engine Speed SettingsFast Engine Speed 2400 RPMIdle Engine Speed 1200 RPMGASOLINE FUEL SYSTEM FOR MODELS (NON-CERTIFIED & TIER I CERTIFIED)WARNING!To prevent injury or fire when servicing the engine fuel system its high fuel delivery pressure must be relieved. First relieve the builtup (trapped) fuel pressure by safely discharging it at the engine fuel injector fuel rail bleeder fitting (Schrader valve).GM 1.6L GASOLINE FUEL SYSTEM DESCRIPTION (TIER II CERTIFIED)This engine is equipped with a fuel injector rail that does not have a pressure regulator. Fuel pressure for this engine is regulated by the engine’sECM controlling the fuel pump via pulse width modulation. The ECM receives fuel pressure and temperature feedback from the gasoline fuelsensor manifold and uses this information to control the ground side of the fuel pump. Fuel pressure is regulated by the ECM pulse widthmodulating (PWM) the fuel pump. The fuel pressure and temperature sensor manifold has a return or “bleed” circuit that is comprised of a .020”orifice and a 6 psi check valve that connects back to the equipment fuel tank. This circuit is used to bleed off any vapor that develops in the lineand returns a small amount of fuel to the tank. The fuel comes from the fuel tank and passes through the inline fuel pump. Fuel exits the fuelpump, passes through the filter and then enters the fuel pressure and temperature manifold assembly. Fuel flows through the feed circuit andis delivered to the fuel injector rail. Fuel that enters the bleed circuits through the by-pass valve in the manifold is returned to the fuel tank.
