Gen 1 purchase info

Hello all. I'm looking to purchase an 05 or newer gen 1 wagon. I will be using mainly as a commuter for work. What do I need to make sure is done on a car before purchase? I know most cars now-a-days have timing belts that need done, do these motors have belts or chains?


Is there a buyers sticky available? I did a search but didn't find much. Still learning to navigate the site I guess. Thanks for any help in advance.

I recently purchased a relatively low-mileage 04 wagon. Here is what I have done so far.

The V6 has a timing chain.

Thanks Dave. I read your thread already! I've checked out the first 10 pages of threads in the gen1 section.

I looked at one today that is making a noise when you start it. How much of a pain is swapping out the starters in these?

Just nuts and bolts. Nothing overly difficult, if you know how to handle a wrench.

Yeah, I'm good with mechanical stuff. I work on a lot of military 6x6 trucks for a hobby.

Welcome to the forum.


I would put a OBDII code reader on it and see if there is anything or it was just reset.
Ask how much oil it uses. They all use oil so if you are told "none" I would be wary. The range seems to be somewhere between 1-2.5 qts every 3000mi.
Ask when the plugs and coils were replaced. A reasonable number for this seems to be 80-100K miles.


There are two real killers for the early model V6's (03-05) and that seems to be an uncorrected mis-fire (plugs and coils) that destroys the catalytic converters and an EGR malfunction that pulls oil out of the crankcase and puts it into combustion.


The last thing I would check is to make sure the transmission fluid is healthy and hopefully has been changed regularly (if ATX).

Good to know. At one point I was of the opinion that manual transmissions were more robust, seems the autos are pretty reliable if maintained. I may have to give the 6sp auto a try.

I've been reading about a lot of cat issues. Is there a way to tell if they've been addressed other than to ask the owner? How hard is it to swap them out? There doesn't seem to be an abundance of room under the hood!

The cat issues really only seem to arise when maintenance is neglected such as misfires (excessive raw fuel entering the cats) or faulty pcv's (excessive oil entering the cats) and it seems to be a bigger issue on the earlier 6's (03-05). As far as replacing them I have not had mine off but the rear one looks fairly easy to get to from under the car the front is a completely different story I imagine by moving the radiator you could probably access it better the real problem would be the possibility of studs breaking off in the head because these engines are aluminum. If you get a later one (06-08- the exhausts are routed differently) you can gut the cats while they are still on the car with a long drill bit (I did this a few weeks ago), that is if you don't have emissions testing where you are.

This is only my personal preference, but I would steer you back towards the manual transmission. The V6 wagon is such a joy to drive with a stick that I couldn't imagine the experience could be matched with a slushbox 🙂

Manual transmissions, wagons, and heavy metal are awesome. Zoom-Zoom \m/
