The front spark plugs should not be a problem. The rear are accessed with use of an "engine tilter". It can be purchased at many auto parts businesses, I purchased mine from NAPA. However, you may have to order one on-line as it is "an unknown item" as many of us are unaware that it even exists and I am sure that the mechanics and techs want to keep it that way. My cost in 2009 was in the $35 to $80 range for the tilter. It may sound a little scarry using it because you loosen the upper (literally right up on top where they are most easily accessed) mounts, but it is easy. I found that no electrical, air flow from filter, exhaust, etc., had to be loosened or removed. You only remove one side and install the tilter. Next you adjust the "tilter" to remove tension on the other bolt. Finally, simply screw the adjuster toward the front of car until you either have enough room to access the rear plugs or until you run out of bolt threads at which point you have as much room to do the job as any tech/mechanic. As usual, remove the old plugs (I only do one at a time which also eliminates crossing plug wires) and screw the new ones in several turns by hand to make sure that there is no cross threading. Once you are satisfied with your level of maintenance, simply adjust the "tilter" back to a point where the loose motor mount accepts the bolt to front frame, tighten it, remove the "tilter" and reinstall the second bolt. It really is that easy, but you will want to protect your paint with a proper cover as you do have to lean heavily against the fender or fenders. Oh, by the way, many mechanics skip the difficult-to-access plugs, knowing that when they, or it fails, you will be back. Enjoy, you will feel like a real pro, knowing that your job was done correctly and is complete!!!

There are 2 different engines that came in the Lucerne in 2006 and I am not sure which one the CXS had. In any case below are pictures of both engines as well as locations. If you have the 3.8 liter (6 cylinder) engine you can add coolant directly to the radiator in the spot marked "A". But on your regular fluid checks you want to make sure that where the "B" is marked that the overflow tank there has fluid up to the line that says "full". If you have the 4.6 liter (8 cylinder) engine the overflow tank and where you fill up the radiator are the same (location "A") so that is the location you would fill the radiator as well as check to make sure there is coolant to the "full" line on the tank on your regular fluid checks, When you look at the pictures below you will understand easier. I hope this helps and good luck.

The P0496 DTC code is a generic code which applies to all vehicle makes.
A quick search on the 'net shows that this code seems to be more common
with GM (Chevy, Pontiac, etc.) vehicles. In Acura, Honda, Hyundai, Kia,
and Mazda vehicles, this code is described "EVAP system high purge
flow" which is the same thing.
try use maxiscan us703 to clear the fault code.
