2000 Mercury Grand Marquis Service and Repair Manual

This factory service and repair manual for the 2000 Mercury Grand Marquis stays with the 4.6L V8 of 281 cubic inches — single overhead cam, naturally aspirated, gasoline — in a GS or LS four-door sedan. What varies between the two trims is equipment, and equipment is where the wiring diagrams earn their keep, since the circuits behind the lighting, wiper, restraint and comfort systems depend on how the car was built. The mechanical procedures, specifications and torque values apply to both trims alike.

Known issues on the 2000 Grand Marquis. Eight recalls sit on the federal record. Two are tightening failures at the plant: retractor bolts for the left rear belt torqued incorrectly, and bolts holding the air bag crash sensor module left loose enough to delay deployment. A wiper control module may not carry the current the wipers draw through ice or snow, stopping them with no warning. Complaints reach 194, spread closely across brakes at 19, steering at 19 and visibility at 18 — the same restraint, wiper and brake circuits the diagnostic charts, torque tables and wiring diagrams here walk through.
