2000 Mercury Cougar Service and Repair Manual

This factory service and repair manual for the 2000 Mercury Cougar has a two-engine, one-body brief: the naturally aspirated 2.0L DOHC inline-four of 121 cubic inches and the naturally aspirated 2.5L DOHC V6 of 155, in a two-door coupe sold as Base or V6. The engine chapters are written twice, once for each, and everything downstream — transmission, brakes, suspension, steering, climate control, restraints and body electrical — is written once, with wiring diagrams and component locations that account for both installations.

Known issues on the 2000 Cougar. Five recalls appear on the federal record. A misrouted battery cable, under-torqued where it joins the alternator cable, can rub the power steering line until its insulation wears through and shorts, which can mean a fire, a stall or a no-start. Filter contamination in the fuel delivery module can starve the engine and stall it. Replacement ball joints supplied with nuts that lack their locking feature can loosen and separate, and replacement master cylinders that lose fluid stretch stopping distances. Of 213 complaints, electrical leads at 51, fuel at 37, engine cooling at 24.
