Cadillac DeVille General Care & Maintenance
A friend recently acquired an 02 DeVille with 35K miles, that is burning a quart of oil approximately every thousand miles. The dealer is telling him this is "normal" for the 4.6 V8 motor. Have others shared this same experience?
Thanks.
Thanks.

Only problem thus far I've had was broken HID headlamp. At 26000 miles, I'd take my good 'ol American car any day.
So here's what I'm planning. New spark plugs (titanium) and wires, tranny flush, radiator flush and the 3K oil change. Should I get a new PCV Valve? Wheel alignment? (there's no shimmy or shake) Les Scwabb says brakes are 50 and 75 %
Can you think of anything I might be missing. I've not been employed for 2 years now and need to be cost conscience. Thanks for any advice.
Oil life indicator shows 75% oil life remaining. 2/3rds
of driving is highway and 1/3rd city all on paved roads.
Am strongly considering waiting until 5 months or 50% oil life remaining on gauge. Would be appreciative of having the input of other Deville owners on this issue of oil life gauge and how often you are changing your oil.
For most of my life I've changed oil, and filter, at 4,000 miles (or every year if I'm driving it less than 4,000/year). I've felt this is a very conservation schedule compared to the 6,000 or 7,500 or even now 10,000 mile schedules recommended by automobile owner manuals.
And not near the 2,500 or 3,000 miles the dealership service people recommend, which is mainly to move money from your pocket to theirs.

I've used oils that will darken up significantly within one week after a change.
But I've been running Castrol 5-20 for a couple of years, and that stuff looks almost like water when it goes in, and it darkens up very little, even over a couple thousand miles. By 4,000, it will be somewhat darker, but this stuff has less color change that any oil I've previously used.
but having only driven 3000 miles in the last four months and indicator at 75% think I will wait til five months. Will probably have only driven 4000 miles by that time.

Oils vary, as Bremertong mentioned, and those systems don't adjust for various oils. One example is if you use synthetic there's no adjustment.

the Mr. Goodwrench or Monroe tire center for less
that $20 bucks (with a lube job) then reset the
worthless oil monitor gadget and drive happy! :P
Having appreciated the comments received here so far I am moving in the direction of 5 months, 5000 miles and 50% whichever comes first. Further comments welcomed and appreciated.
The warmed garage also helps on the contaminants left in the oil in cold weather during starting warmups. Our cars are in garage at minimum 40 deg. F. in winter. Usually 50. If your car is treated that way and not started in cold weather with a cold motor regularly (at work to come home) and your summers are rarely above 65, you can make the extra miles and change twice a year very safely. You're the closest to the normal description for ideal service intervals I've read.

They said was just about full. I have owned the car for two years and this is the first time this has happened. Plan to wait and see if it happens again. Have others had this message when the coolant level was full? If it happens again I will need to have Cadillac dealership check. Could it be a faulty module or some such thing?
frustrating to have the coolant issue come up today, guess I have been lucky in that in the five years of ownership of two Devilles this is the first time a check anything message has come on.
There is sometimes water on the tray but have assumed it is condensation from the air conditioning system, it is off to the the side at about where the driver seat is. If the water pump is leaking would water have color to it? if so what color should I look for? Would there be leaking even if the car had not been out for a day? Is there a particular location under the car that a water pump leak
would appear on the garage floor or tray (2004 Deville)?
If you still have the right coolant, it should be the orange stuff. Your dealer can do a pressure test, which will take some time, to see if the cooling system is leaking. The water pump leakage can be intermittent till it fails and the engine overheats.
schedule a service department visit with a Cadillac dealership. Will probably go to the dealer 60 miles away in that I was more impressed with them than the dealer closer to me. I am scheduled for an oil change in the next two to four weeks and if no further coolant message occurs I will wait and mention at oil change time. So far as I know the coolant is the original that came with the car.
A leaky water pump should have left some evidence and since you are checking for an oil leak, I think that you should have seen something. If you are getting an oil change soon, you can have it checked out then. At this point I would not panic. They should put some coolant in though, to prevent additional messages. Then, you should monitor the coolant level for the next several weeks to be sure that coolant is not disappearing.
I recomment monitoring the coolant level on a regular basis anyway, when the oil level is checked, like weekly or at least 2 to 3 times monthly.
a "glitch" on these new gadget laden vehicles !
Sure you weren't out "driftracing" or doing a few
WOT passes cleaning the carbon outta that N-star
monster motor? I have to take out my moms DeVille
and beat on it once in a while to clean it out!
Most likely just the coolant in the res. just sloshing
about and triggering the low coolant message.
But before a wasted trip to the dealer keep a eye on
your coolant level................. :shades:
res. on my 03 DeVille.
You should just be able to "eyeball" the coolant
level and note the level. It should just unscrew
off tho..................
I would say its best to check when cold and engine
not running.
My northstars have a reservoir that is transparent on the lower half and the coolant should be near the top of this transparent part when the engine is cold. When the engine is hot, the coolant level should be higher, possibly hidden in the opaque part.
If the cooling system has a leak, then the reservoir may remain full while the radiator is low. This is so because as the radiator cools the leak lets in air instead of water from the reservoir.
As I said before, your cruise control problems might be an indication of wiring problems, and so if this was a false alarm, perhaps the wiring problem is speading. I do not put a high probability on this explanation however.
we found none but in the event the check coolant message comes up again will get in to the more distant GM dealership ASAP. The original warranty runs out in July 2007 so I have
a year and have purchased an after market warranty that runs to 100,000 miles and seven years. Car currently has 33,000 miles on it so my original warranty will run out on date rather than miles as I only expect to put about 10,000 miles on the car in the next year.

and lube ALL the zerk fittings:

coolant return line to the overflow bottle.
Could it be a loose clamp or even a cracked overflow
bottle? Maybe a bad coolant res.level sensor.
I read on the GM truck forums about many guys
who have discovered cracks in the res. bottle itself.
I know the newer Caddies and other GM vehicles
don't have a rad. cap anymore.
Luckily my 03 now has 41k troublefree miles............
Keep us posted!
If the reservoir is cracked, it will, under pressure, quickly vent the coolant in the cooling system.
in dash cd changer, automatic opening and closing trunk, many of these features were on my 98 Deville but not on the 2004. The Lincoln is more floaty but more quiet car than the Deville. The Towncar had 16500 miles at purchase and well under half the price, new in April of 2005. As you know the Deville engine is higher power rated but have been pleasantly surprised at the power the Towncar has especially from a standstill. Nice feature is also a button on the shifter that shifts the transmission out of overdrive into third gear for quick extra power. Like my 98 Deville it is in Gold which is my favorite color. The two cars look great parked next to each other in the garage. At this point I can't say there is a first or a second but both are tied for first. Only problem so far with Towncar is a slightly loose door handle strap on the driver door.
It will be interesting to see how these two fine cars perform in both reliability overall. If you were wondering, I generally keep my cars for average of three years but I decided that I wanted a companion car more like the Deville.If there are other Deville owners that also own Lincoln Towncar would be interested in your experiences and comparisons.
