Recall History (2 recalls)
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS
THE PLASTIC BRAKE HYDRAULIC HOSE FROM THE AUTOMATIC SLIP CONTROL UNIT WAS MISROUTED TOO CLOSE TO THE PRE-RESISTOR FOR THE ELECTRIC AUXILIARY ENGINE COOLING FAN WHICH BECOMES HOT UNDER CERTAIN CONDITIONS. THIS COULD CAUSE THE HOSE TO MELT AND LEAK BRAKE FLUID ONTO THE HOT PRE-RESISTOR.
ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
HIGH AMBIENT ENGINE COMPARTMENT TEMPERATURES ARE EXPERIENCED AFTER THE VEHICLE IS OPERATED AND THEN PARKED. IF THE VEHICLE IS RESTARTED A SHORT TIME LATER AND THE CHARCOAL CANISTER IS SATURATED WITH FUEL, IT IS POSSIBLE THAT FUEL VAPOR MAY BE EXPELLED THROUGH THE INLET VENT LINE OF THE CANISTER ONTO THE ELECTRIC AUXILIARY RADIATOR FAN PRERESISTOR.
