1986 Ford Aerostar Service and Repair Manual

This factory service and repair manual for the 1986 Ford Aerostar covers three gasoline engines: the 3.0L OHV V6, the 2.8L OHV V6 and the 2.3L SOHC inline-four, all naturally aspirated. Two body styles are included, the two-door mini passenger van and the two-door mini cargo van, across the Base, XL and XLT trims. Procedures, specifications, torque values, wiring diagrams and diagnostics are laid out by system, so the same book serves every combination of engine, body and trim.

Known issues on the 1986 Aerostar. Eight recalls are on federal record for this van. One concerns fuel tanks that may have been scored or punctured when partition mounting holes were drilled through the floor pan; another covers spring-lock fuel line couplings that could work loose under pressure and vibration and leak fuel; a third involves power lumbar seat wiring routed under the cushion springs, where abrasion could cause a short and a fire. Owners have filed 72 complaints with NHTSA, clustering on the electrical system, engine and engine cooling, and the power train. The wiring diagrams, fuel system procedures and engine diagnostics in this manual address those exact systems.
