I'm a Mopar guy. and the less said about this turd of an engine the better. Where it really gives trouble is in the 98-2001 LH cars. A combination of an even worse pump design and inevitable high RPM operation caused by placing this engine in a huge car leads to some truly spectacular failures.
The sad thing is that this engine ruined the reputation of what is actually decent car. The Concorde LXi and Intrepid ES from the same year range with the 3. 2 (and the LHS, 300M and Intrepid R/T with the nearly identical 3. 5L) are nearly bulletproof save for solenoid packs in the transaxle and some weak spots in the cooling system (heater crossover tube corrosion and O-ring failure, coolant bottle cracks, etc. As for the infamous 42LE solenoid pack, replace it with a new Mopar one. It's the only way to ensure that you'll get the redesigned part that doesn't fail often. Oh and the Mopar thermostat on the 3. 2/3. 5 engines is of a unique design. The aftermarket ones have a smaller orifice which leads to wider temp fluctuations that will crack radiator end tanks in due time.
I currently have 265K on my 2004 300M Special with the original powertrain. It still passes smog without any funny business too. Besides the aforementioned cooling issues and a solenoid pack, the only other non maintenance items I've done are a new PCM, a new trip computer, a new mirror switch, a new high side line in the A/C and an aftermarket trans cooler to help the trans live longer down here in the Texas heat.

Advance Auto is very good about its return policy - to the point they act as a rental agency. No problem returning stuff if you're interested in endlessly returning the crap they sell. The problem is that you have to F%&ing pay somebody every time it happens. There is no excuse for these substandard parts to be in circulation - except that Advance, Pep Boys, and the other big chains have put the small guys out of business - the people who had to sell you good parts in order to stay in business. well, that's the way it used to be, anyway. The biggest problems will happen when Chinese suppliers become OEM suppliers. We're screwed. Pay attention to the mechanics who work every day with these shit parts - they are the canaries in the coal mine.

you have to be careful buying parts at advance auto, i dont buy airtex, or tough one, wearever brakes, exact spark plug wires, the last wearever pads i put on lasted 12000 miles. all these from advance are junk. just make sure you keep your receipt because they only keep record of your purchase at the store where you purchased the item, once the memory is full in there system all the data is dumped and deleted. lifetime warranty parts from advance is a joke. advance auto is 7miles from my house and autozone or oreilys is 16 miles away so its sometimes worth the extra drive to get a good warranty and parts

I have that same engine in my Dodge Magnum and had now over 230. 000 miles on it when I had to take it apart because of a blown head gasket. I changed out the water pump and working right now towards the oilpump as well. But had zero problems with it. Running it on full synthetic amsoil 0W-20 here in Florida for most of the years and zero problem I have a video series about the head gasket products and put all my work I done to the car online so for who ever is interested can watch it.

Also the old Chysler pumps were modified i think the boss water chamber casting was of less height because of the timing chain was sawing through them, hence water in the oil when the tensioner /guide let go, + the plastic fins went tits up and the bearing was crap, the modifired pump also had the sprockets pushed thuther out when desigers make crap like this that cost owners hundreds or thousands of dollars should be prosicuted!
Chrysler is a shit product!

I bought the parts for my 2006 sebring sedan and after watching your video i took the new pump and i measured it lucky, 0. 482.
but i know that some water pump for the 2. 7l uses different type of gasket like the black one made of gasket paper or the like.
i wonder if the thickness of this gasket is sufficient to allow the cover to fit or the pump could be too far in and miss aligned with the timing chain.
It would be nice if you could dig that

1: 20 and 3: 14 you can see the difference. The pump on the left has the larger fill for the internal grease for the bearing, part of the 2007 redesign, 2006 has the little grease fill. These are plugged after grease is installed. The advance pump is for a 2007-2010 2. 7. Chrysler changed the water pump 3 times on these engines. 1998-2001, 2002-2006 and 2007-2010.

Man that sucks, all that work for nothing, hard to believe. 080 extra thickness would make that not fit- Since the pump body is 080 thicker does that also mean the chain would be running at a slight angle?
Maybe you should try to get dealer parts? I know they are much more expensive but maybe worth the extra for a customer

i ran into this same problem with an advance auto pump. the old pump has a thick aluminum pump gasket with rubber seals. the new pump comes with a thin paper gasket. use the thin paper gasket with oil resistant rtv to seal it. the new design has a thicker pump body and the thinner gasket compensates.

Advance Auto is now selling Carquest parts because of their buyout. I wonder if they are better.
I have had various issues with ToughOne alternators and starters. Warranty them off with the Carquest equivalent and all is well. hmmm. still from CHINA, though.
