BREM:........Still losing coolant? There is a hidden
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!

As I pointed out before, the radiator on the northstar engines is not something that the owner can get to. The radiator is under some shrouding and the cap, if there is one, is not accessable. Also, the so called reservoir is sealed and when the engine is warm/hot, the reservoir is under pressure. So, the only way to visually check the coolant level is by looking at the reservoir level.
If the reservoir is cracked, it will, under pressure, quickly vent the coolant in the cooling system.

From what I can gather it was evaporation and not a leak we added a little dexcool at my oil change on Tuesday of this week. By the way after owning my Mercury Sable 2005 as second car for about four months I decided I wanted a real twin for my Deville. Was fortunate to Find a Limited Edition of Lincoln Town Car vintage 2005, got about what I paid for the trade on the Mercury. The Mercury is a fine car but the Lincoln is awesome with extras like a sun roof,
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.

It is normal to add some (~1 pint) coolant after a year. The reservoir is sealed, so there should not be much evaporation.

Don't think that is in the owners manual, if it is I missed it. I bought the car at eleven months old so the additional pint you refer to may not have been added. The check coolant message has not come on since the service date five days ago, would guess they added the right amount of coolant. Check tire pressure message has come on several times during a mini heat wave we've had temperatures have been around 90 for a few days. When the message first came on a few weeks ago I dropped the pressure from 35 psi to 33and a half, guess it was not enough in that the message flashed again several times on past Saturday. I set the pressures with cold tires in the morning. The message comes on when the pressure hits 38 in any tire. Suspect the heat wave will be over in the next few days, but may have to drop them to 32 psi cold if check pressure message keeps flashing. I use an electronic pressure gauge to check pressures and in normal weather the gauge and the on board system are generally in 1/2 pound of each other. Any ideas or suggestions? Many thanks!

I had a 2004 and now a 2005 Deville with the tire pressure system and it didn't matter if we went from Indiana to Florida or whether it was 15 degrees in the winter or 94 degrees in the summer we didn't get a tire message unless there was a significant difference in pressures from tire to tire. I wonder if you have a lot of moisture in your tire's air? Do you have a really good gauge? Do you do the manual tire pressure check in the car after setting pressures to see if your gauge matches what is in the tires according to the sensors? You may need to drive the car a bit to reset the sensors and then do the manual check with the button on the dash. This is something else you may want to take up with the dealer. Bob

What I was getting at, and I am sorry that you did not understand, although I am not surprised, is that adding 1 to 2 pints of coolant annually (that is after a 12 month period) is normal; BUT, adding a gallon every 12 months is not normal. I hope that this is clear?
More to the point, adding 1 quart in the next 12 to 15 months is probably not anything to worry about. But adding 1 quart in the next 6 months is something to worry about.

I owned my 98 Deville for a little over three years and never added any coolant and never had any coolant messages. If your stats are correct why is that? It would seem to me that after three years a message would have appeared. The car also ran fine, the service dept would give me a report on fluid levels at oil change time and if any were added. Thanks again for the information.

This problem has only happened during the hot weather recently. The temperature has been about thirty degrees warmer than usual. The dashboard readings and my manual pressure reader are generally within a half pound of each other. We will see what happens after the heat wave. If the pressure reading warnings continue to appear I will check at the dealer. Many thanks for the response.

I don't think that you should need to add any coolant over a period of one year. My Seville had some transmission work done more that a year ago, and that required the engine/transaxle to be removed from the car, so the coolant was replaced. Since then the coolant level has remained completely full, up to the top of the transparent portion of the reservoir when cold.
What you should do is monitor the coolant level, when the car is cold, and note when it starts to disappear. At that point you need to become concerned that a leak has started, or the water pump is beginning to fail.
Someone I know has a 99 DeVille which had a water pump failure. After some period of time the DIC flagged the Low Coolant warning, so he had the dealer add more coolant. A few months later, the warning came back, and the service department knew that there was a problem, which should have been checked for sooner. The problem was a leaking head gasket, which they tried to replace, but there was so much corrosion that the engine was not repairable. The warranty was also expired.
