@@joshmori9023 this is so true.

How is it holding up?

ChrisPFlorida1 Do you still have it?

I agree 100%.

Crossovers are atrocious enough, but the “Cadillac” crossovers GM is crapping out today are _abominations_

@@davidpar2 - When GM decided to drop Pontiac, Saturn, and even Oldsmobile several years before, they should have also dropped Cadillac. If you're not going to keep and respect the history and traditional styles of a car brand, then it's time to leave well enough alone and let it go. At least Lincoln somewhat kept that classic tradition going with the new Lincoln Continental.

84 I'd say this was the first year of the downsized model

LOL I love the old caddies and lincoln cars! Hard to find nowdays!

What??? 4 doors are sedans. 2 doors are coupes. The Eldorado was the sister car to this which was the coupe.

If you have the 4.9 you don't own this car. 4.9 was never offered until 1990. The first two years of production on this body style you could have had the 368

Nope. They are more of a sport luxury these days.

stellarfungk85 Yes it's true. There is a decal under the hood that mandates the use of stopleak to prevent major engine damage. This applies to 4.1,4.5,4.9 and Northstars up to around 2003. The stopleak is available at any GM dealer. They are also known as "Coolant Cookies" or "radiator tablets/pellets" hence they are brown tablets. The HT Series requires 6 cookies while the Northstar requires 3. The cookies seal up the headgaskets WHEN they blow just like Cadillac engineers knew they would blow...LOL!!!

Yes it is a gorgeous car! :)

Thanks for your reply. Now I'm glad that I didn't end up buying this car after all! If course this Caddy is nice to look at, but it's very problematic under the hood unfortunately. :( It makes you wonder why GM would put something like that out knowing in advance how faulty the engine is!

stellarfungk85 I would guess it was a combination of an arrogant and or cocky attitude from the engineers and the pressure from the EPA to meet CAFE standards. The engineers knew the engine would last throughout the warranty period with the use of stopleak so I guess they didn't care about the engine in the long term. I had an 86 Seville with the 4100 and an 88 DeVille with the 4.5. They both blew a headgasket even with the use of the stopleak. My 88 blew the headgasket so bad the stopleak only temporarily sealed the leak. On the 86 the stop leak became the headgasket after it blew. It took 12 cookies and I could see the stopleak seeping between the heads and the block and smell it as I drove. This happened at 113,000 mi and I kept the 86 until 125,000. The 88 Deville blew at 91,000 mi and required a $3500 engine rebuild. I hope this gives you a general idea on how long these engines last.

How many cadillac Sevilles you have

How so?

It drive fast but NOT made for performance..lol

Yeah, me too. In 2012, I had a 1985 Lincoln Continental sedan.

+Swapan Ghosh yes it was . i have one hear in west australia cheers

thanks sir for the information.

MegaZeldafan1 although the Fleetwood and brougham are nice.

They always blow head gaskets and have overheating problems

Just LS swap it. It’ll fix the HT4100 problems.
