Fuel Economy Overview

The 1986 Ford Bronco II 4WD achieves an EPA-estimated 17 MPG in combined city and highway driving, with 15 MPG in the city and 20 MPG on the highway. Powered by a 2.9L 6-cylinder engine paired with a automatic 4-spd, this special purpose vehicles features 4-Wheel or All-Wheel Drive drive.

In terms of environmental impact, the 1986 Bronco II 4WD produces approximately 523 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Bronco II 4WD has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,500, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $6,750 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Aerodynamic Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

Campaign #88V145000·1988-10-13

critical

Component: SEATS

WIRING FOR THE POWER LUMBAR SEAT SYSTEM WAS ROUTED DIRECTLY BENEATH THE SEAT CUSHION SPRINGS AND MAY BE ABRADED BY THE SPRINGS.

Consequence & Remedy

Consequence: THIS COULD RESULT IN A SHORT CIRCUIT WHICH MAY CREATESUFFICIENT HEAT TO START A FIRE IN THE SEAT CUSHION PAD AND/OR TRIM COVER.

Remedy: INSTALL A FUSE WITHIN THE POWER LUMBAR ELECTRICAL CIRCUIT.

SPRING LOCK FUEL LINE COUPLING MAY NOT BE PROPERLY ENGAGED.

Consequence & Remedy

Consequence: COUPLING COULD DISENGAGE DUE TO FUEL PRESSURE,VIBRATION, AND ENGINE MOVEMENTS; THIS WOULD CAUSE LOSS OF FUEL WHICH, INPRESENCE OF AN IGNITION SOURCE, CREATES A FIRE RISK.

Remedy: INSTALL RETAINER CLIPS OVER THE COUPLINGS TO PREVENT COUPLING SEPARATION AND FUEL LEAKAGE.

Campaign #85V116000·

critical

Component: ELECTRICAL SYSTEM:WIRING:FRONT UNDERHOOD

THE ELECTRONIC ENGINE CONTROL WIRING HARNESS INSULATION MAY BE DAMAGED DUE TO COPPER SPIKES PRODUCED DURING THE WELDING OF ITS WIRES. THIS CREATES A POTENTIAL FOR A SHORT CIRCUIT BETWEEN THE WIRES WHICH ENERGIZE THE FUEL PUMP, CAUSING SOME FUEL INJECTORS TO OPEN, DISCHARGING FUEL INTO THE ENGINE. CONSEQUENCE OF DEFECT: FUEL DISCHARGED INTO THE ENGINE WOULD EVENTUALLY LEAK THROUGH THE EXHAUST SYSTEM TO THE GROUND. THIS COULD RESULT IN A FIRE IF A SOURCE OF IGNITION IS PRESENT.

Consequence & Remedy

Consequence:

Remedy: REPAIR WIRING HARNESS, CHECK ENGINE AND CATALYST FOR DAMAGE.
