So a "normal" temperature at idle can be anything from a dead cold startup to 224 degrees. On the highway temp will sit at about 12 o'clock on the gauge (which is highly damped) so you'll have temps of 190 - 210. In heavy traffic, summer, no A/C on the temp will crawl to 224, fans go to SLOW, the engine cools to 213 and it starts all over again. With A/C or DEFROST on fans run all the time so temps will sit around 12 o'clock.
The Eldorado never got the updated 180 degree sweep gauge after 2000 - it still used the obsolete 135 degree sweep and still had the "Premium fuel" note on the gas gauge (that's incorrect for 2000 and later). In my albums there is an annotated temp gauge - the tick marks still correspond to the Eldorado temp gauge ticks. Click my username, open the profile.

FWIW, the ETC uses the VIN 9 300 hp engine and a 3.71:1 performance final drive. The ESC uses a VIN Y 275 hp engine with a 3.11:1 economy final drive. A VIN 9 car will give up 2 - 4 mpg to the VIN Y on the highway. In the city they're close - 12 to 16 city, 16 to 20 suburban, on the open interstate - 28 or so for the Y and 25 for the 9 in perfect tune and driven well. Speed vs. rpm tables (TCC engaged) in my albums.
ETC vs ESC
ETC is the more expensive full options (luxury and performance) model.
ESC is the base model
ESC most of the time has passive suspension, less wood grain, less options and the grille colored in silver plus the engine is 275hp, 300·ft w/3.11:1 final drive.
ETC has always the active suspension, full stability system, full wood trim, is prone to have more options, the grille is colored in the car body color and the engine is 230hp, 295 lb·ft w/3.71:1 final drive.
The ONLY difference between the 2 engines is the headers (exhaust valves) and in the transmission the final drive gear. Other than that powertrain wise the cars are identical.
These cars did not had many options, most have everything with little extras to choose. Among these is the BOSE sound system with InDash CD slot (for '98 and up), 4 speakers with individual amplifier for each and a RIM (the module that does most of the sound processing). Base cars had the classic layout sound system (no InDash CD slot), where everything is in the HU (what most people call the stereo) and conventional speakers.
Either one of the 2 sound system can be extended with a 12 Disk CD changer (same unit for both). The ESC being the economy model, most people ordering a ETC were on a budget thus not opting for very expensive extras (like the sound system) as a result BOSE sound system is not very common in ESC cars.
The other bigger scope option was the Moonroof.
There was a choice of rims and tires. The rims choice was brushed aluminum (standard) or chrome (same exact rims but chrome finish - as option). For tires there was the S of H speed rating tires (for ESC) and H or Z for ETC. Based on the tire choice the car top speed was limited to the tire rating. For the cars equipped with Z rated tires there is no speed limiter.
The memory package (mirrors, seat) was optional (but very common) for the ESC and standard for the ETC.
The other option was the Cell Phone package, not very popular with either of the ETC or ESC. This was option could be used as OnStar (analog). In ’00 the OnStar as stand alone system became an option (not too common).
Home Link garage door opener was optional in both cars.
At some point the compass/self-dimming mirror was an option, by ’98 I believe it became standard even in ESC.
The Rainsense wipers were optional for ESC (but pretty popular).
For the ’99 production year exclusively there was a very rare option available, massage seats. Only about 750 cars were ever made with this option.
Still with seats, I believe for the southern cars the heated seats (at least in ESC) were optional. I have never seen northern cars (especially ETC) w/o Heated seats.
Again about seats, the difference between ETC and ESC is the ETC had perforated leather inserts while ESC did not. Other than that the seats are identical.
Wood wise, the ETC had wood inserts on the door panels while ETC did not, also ETC has wood trim around the shifter panel whereas ESC does not.
For the older cars (prior to ’97) some of the standards were options or none at all. Generally ’95 (’96 to some extent) and older cars were quite different although look the same on the outside.
That is pretty much it.
Exhaust cams ...............
From what N*Caddy stated, my 650 ESC was well spent. The only thing I don't have is moonroof, rainsense, "9" motor, heated seats, on-star and cell phone package.
I'm adding the wood steering wheel, wood shifter plate, wood ashtray, (TL4 painted grille). On the fence whether or not to go to the painted rear liscense lamp pocket.

Uh, I think N*Caddy pretty much covered it.
The leather and wood steering wheel, BTW, was not standard on the ETC, it was a rare option.
Sorry did I said valves... I meant cams.
Woodgrain steering was an ETC only option (at cost) available only after '02. This means, not many are available as the production numbers were drooping towards the end of the run.
Eldorado are so rare these days in my area that this morning is the first time in quite some while when I saw one in traffic.
I only know of 2 Eldorado locally (friends) and that's about it.
If I see one every 2 months is unusual. In 7 years I have only seen 2 in wrecking yards.
I just looked in my beloved Eldo.......I HAVE heated seats........lol.
Whoever orginially ordered this car , wanted everything but an ETC set up...........
[QUOTE=Submariner409;3206212]The car is sitting there, idling. With the A/C off: The cooling fans don't come on until 224 degrees. The gauge will go almost to 5/8 when that happens. Normal.
Dillontheman, The 1998 engine year is statistically one of the two worst for head gasket failure due to the head bolt threads in the cylinder block failing - and that's an extensive expensive repair.
Whats the "other" year in which N* was statistically one of the 2 worst?
'99 was the worst, according to the unscientific poll on this site.
Two words and im out: MONEY PIT
I'm suspicious of the milage. That shifter looks too warn to have what is claimed.
