Replacing the alternator on a 2005 town & country

It depends where you live. Mechanics charge between $45-$125 an hour plus parts. Do a search on line for the labor time needed to replace a master cylinder. Mechanics usually look this up and calculate their hourly rate this way. Private mechanics will be cheaper than dealers mechanics.

Wrenches-- loosen bolts holding it in place, move it so belt comes loose. lift belt off pulley, undo bolts and remove alternator. use reverse process to install.

You should have 13.5-14.9v at the alternator with the engine running.

if you have the battery handy , replacing the old immediately should not alter the programming
the program will not hold indefinitely but replacing is a may be 30 second job and most key fobs hold the program for a minute

just fixed rattling problem on my 2005 grand caravan 3.8 replaced alternator pulley has a clutch effect when i twist it back and fourth by hand could hear rattling and squeaks replaced alternator and pulley and rattling is gone

yes you are correct.

Replace your battery. It is low/not holding a charge and you are slowly burning out your alternator by boosting and running the vehicle. Once the battery is replaced, put a volt meter on the alternator and it should read between 13.9 and 14.2 volts. If it does not, replace the alternator.

I have the same vehicle. when the sun comes up I will go out and look my self and get back. It should let me post a follow up.

You can buy a haynes manual to remove it but most manals won't have that information, why do you want to change it and if you have a camera I can tell you how to remove and replace it if I have a picture of it.

This either means your battery has failed or the alternator. You can use a voltmeter to monitor battery voltage it should maintain at least around 13 with lights on if it gets low and car eventually stalls replace alternator. Thanks
