How do I change a altinator on a 2002 Mercury Cougar


Is this a v6? It comes out through the wheel-well. So you have to safely raise and support the vehicle, remove the tire, remove tie rod end from steering knuckle. Remove wheel well liner. Take negative battery cable loose, take belt loose, take wiring connectors loose from generator, remove bolts from generator, remove generator.

I'm not aware of an alternator light, only a voltage gauge. It sounds like you need a new battery. Another (cheaper/easier) troubleshooter is to take the cap off of the cells on the battery itself.

Check all the vacuum hoses and see if they are broken or disconnected. Surge in power issues, idling issues, engine stall while driving, all are related to vacuum hoses. Give a try.

In some 1999/2000 Cougars the wire between the battery and the voltage regulator(altenator) had a resistance reading that is too high. Ford has issued an TSB 00-25-6 that has instructions on how to replace this wire. The part # for the replacement wire is
