VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH VR6 ENGINES. A COOLANT SYSTEM COMPONENT SUCH AS THE THERMO SWITCH, RADIATOR FAN, OR WATER PUMP, CAN MALFUNCTION CAUSING THE COOLANT TEMPERATURE AND COOLANT SYSTEM PRESSURE TO INCREASE SIGNIFICANTLY. OVER TIME, EXCESSIVE PRESSURE CAN CAUSE LEAKAGE OF COOLANT FROMTHE SYSTEM, INCLUDING LEAKAGE FROM THE HEAT EXCHANGER.

Consequence: LEAKAGE OF HOT COOLANT FROM THE HEAT EXCHANGER CAN CAUSE INJURY TO THE FEET OF THE DRIVER OR STEAM UP THE INTERIOR OF THE VEHICLE TEMPORARILY IMPAIRING THE DRIVER'S VISION.

Remedy: DEALERS WILL INSTALL IN THE COOLANT INLET HOSE TO THE HEATER CORE, A PRESSURE REDUCER WITH A 5MM DIAMETER SECURED BY A SPRING TENSIONED HOSE CLAMP. ALSO A NEW RELAY THAT WILL CHANGE THE OPERATION OF THE SECONDARY ELECTRICAL COOLANT PUMP WILL BE INSTALLED. DEALERS WILL ALSO PERFORM A FUNCTIONAL CHECK OF THE COOLING SYSTEM TO MAKE SURE THAT ALL COOLING SYSTEM COMPONENTS OPERATE PROPERLY.

AN ENGINE COMPARTMENT ELECTRICAL WIRING HARNESS MAY HAVE BEEN ROUTED TOO CLOSE TO A SHEET METAL EDGE. THE WIRING CAN BECOME DAMAGED DURING NORMAL VEHICLE OPERATION DUE TO CHAFING, RESULTING IN AN ELECTRICAL SHORT.

Consequence: IF A SHORT OCCURS, EITHER THE ENGINE COULD STALL ORTHE RADIATOR FAN COULD STOP OPERATING CAUSING THE ENGINE TO OVERHEAT. EITHERCONDITION COULD RESULT IN A VEHICLE ACCIDENT.

Remedy: REROUTE AND SECURE VARIOUS WIRING HARNESSES INSIDE THE ENGINE COMPARTMENT.

THE FUEL HOSE ATTACHED TO THE FUEL DISTRIBUTION RAIL ON THE ENGINE MAY SHRINK BEYOND THE CLAMP FORCE OF THE FUEL HOSE CLAMPS, ALLOWING FUEL TO LEAK.

Consequence: FUEL LEAKAGE IN THE ENGINE COMPARTMENT CAN CAUSE AN UNDERHOOD FIRE IF THE FUEL COMES IN CONTACT WITH A SOURCE OF IGNITION.

Remedy: REPLACE THE FUEL HOSE ATTACHED TO THE FUEL RAIL AND INSTALL A NEW SPRING TYPE SELF-TIGHTENING CLAMP.
