  1. Finally got around to doing this. I was only able to get about 6 quarts of fluid in after the change. That's just the capacity of the radiator, reservoir bottle, and hoses it seemed like. So over half the fluid you can't get it since it's stuck in the HVAC system. I drained it, then refilled with water. Let it warm up and circulate fluid, then drained again and refilled with fluid. When I refilled, I open the bleeder screw on the hose by the thermostat mount. I'm not too concerned with only changing out half the fluid. Fluid looked perfect coming out, at 105k miles of hot desert usage.

    BTW, the radiator drain petcock is the worst ever. You loosen it completely, and it only pisses out a tiny stream, would take an hour to drain. So you have to loosen all the way and pull the whole valve out, making a huge mess all over yourself. But whatever, it's done now. The hardest part of the job was taking out the dozen bottom air dam panel fasteners without trying to break them!

  2. If you ever plan to have passengers in the back though, I would definitely get the third row option just for the rear HVAC vents and controls. That's a huge benefit in cooling the vehicle quickly. I can't imagine it's that much extra weight, maybe 50 lbs or so. Nothing like the extra weight of AWD.

  3. So I hit 103k miles the other day. I already changed my transmission fluid and spark plugs recently. The next big maintenance item looks like a coolant flush at 104k miles. It's still on the original coolant on my 2012 3.6l. Are there any gotchas to the coolant change for this vehicle? Or is it just a simple normal change:

    1. Open the radiator drain and the coolant reservoir bottle. Let it drain completely

    2. Refill with distilled water. Run vehicle for awhile till thermostat opens and circulates the fluid

    3. Then drain the fluid again. This is to get rid of the hidden remaining fluid after running the engine for awhile.

    4. Then refill with the proper 50/50 mix of Chrysler MS-6395 compliant red HOAT coolant.

    5. Then bleed the system. Do you just run the vehicle with the coolant reservoir cap left off? Run it long enough until the thermostat opens and fluid level drops a bit?

    How much fluid should I expect to use? The 3 zone climate control says 14.5 quarts. But I highly doubt you can get it all out of the system. Unless there's some special way to drain everything from the system? How much do you actually drain from the radiator?

    Side topic, I haven't replaced the PCV valve yet. Where is that located?

  4. So I finally got around to changing my spark plugs at 100,500 miles. The job was much easier than anticipated, 2 hours methodically taking my time since I hadn't done it on this vehicle before. The plugs were definitely in need of replacement, couple of them had a decent amount of buildup around the electrodes. I'm sure I'll pick up a couple mpg's hopefully!

    There was quite a bit of oil in the intake manifold running around. I cleaned it out the best I could. Should I be concerned about so much oil there? Does that mean there's a problem?

    FYI, you only need the 6 upper intake manifold gaskets (the square ones). You don't pull the lower intake manifold off, so no need to replace the lower intake gaskets (roundish ones).
