My mechanic is saying I need to replace the alternator and battery in my 2007 Chrysler Pacifica. I only have 79000 miles -- isn't this a little soon for the alternator?

    What ever you do do not disconnect the battery with the engine running. The battery is a load on the charging system and keeps system voltage in check. Disconnecting the battery when the charging system is operational can cause a voltage spike that can destroy modules and computers in your electrical system. Changing an alternator is not uncommon for some lower milage vehicles as more and more demand is being placed on them, the battery 5 years is about normal.

Are you having trouble with your battery going dead? Alternators can go bad at anytime depending on several things, but most cars today will run over 100,000 miles with out a problem. As long as your charging and your not hearing noises from the Alternator you are ok.

It is a little soon but not unheard of. If you start your vehicle and disconnect that battery does it DIE? If it does either the Alternator or the the voltage regulator is bad. If it doesn't then most likely it is just your battery, not common in one this new but surely possible.

2007 Chrysler Pacifica. I changed the alternator and the battery. The car starts but cuts off. What is the problem please?

Question edited to clarity and spelling.

The anti theft system is working well for you. The key probably wasn't in the ignition when you connected the battery back up. Number one tip, always maintain power when changing batteries with a couple of pieces of wire.

I have a 2007 Pacifica 4.0 I changed the alternator now when i give it 1/3 to 1/2 throttle trac control and check engine light comes on ck engine blinking abrupt misfire.

Hello. It seems your Chrysler needs a tune-up; new spark plugs and new spark plugs cables. This is why your vehicle has a 'misfire' and 'power loss' resulting in limited acceleration. Good luck and keep me informed; if you want to.

How do I change the spark plugs on a 2007 Chrysler Pacifica?

the upper plenum will need to be removed on the 4.0 liter. Once the plenum is out of the way the coils can be removed and the plugs replaced.

on the 3.8 liter remove the plug wires from the plugs one at a time and replace that spark plug. Place the wire back on the plug as soon as it is installed and move on to the next.

Why does my 2007 chrysler pacifica gets stuck in 1st gear

You should first take it & have someone hook it up to a scanner & if it`s not the solenoid which is a common problem, then it`s something mechanical. Let me know.

The heat does not come out on my 2007 chrysler pacifica what could be the problem ?

I know that you have probably already figured this out but I thought I would post in case someone else was looking at this like I was. My heater wasn'y working properly in my 07 Pacifica and would only get hot after I drove it at fast speeds but as soon as I stopped it would blow cold again. It ended up being a small hole in the radiator. As soon as they filled it with antifreeze it worked normal again. So a quick easy cheap check would be to check the coolant first.
