1987 Mercury Colony Park Service and Repair Manual

This factory service and repair manual for the 1987 Mercury Colony Park describes a wagon with nothing optional about its powertrain: one engine, the naturally aspirated 5.0L OHV V8 of 302 cubic inches burning gasoline, in one four-door wagon body, sold as GS or LS. Because there is no second displacement to sort past, the fuel, ignition, cooling and emissions material applies directly to the car on the lift, and the specifications, torque values, wiring diagrams and diagnostics carry on through the chassis and body work that both trims share.

Known issues on the 1987 Colony Park. Owner reporting on this year is thin: two complaints in total, one logged against the electrical system and one against the service brakes. Two entries are far too few to call a pattern, but they name systems a load-carrying car of this age tends to want attention in, and both are set out here in full — circuit diagrams, connector and ground locations and charging output checks on the electrical side, and hydraulic bleeding, pad and shoe specifications, rotor and drum wear limits and pedal travel diagnosis on the brake side.
