1982 Cadillac Deville Coupe HT4100 4.1 L V-8 from North America

Summary:

A ticking time bomb

Faults:

I put a new alternator in shortly after purchasing the car.

I put a new windshield in because the old one was chipped from age.

Was about to replace the exhaust system, which had rusted through, right before I got rid of the car.

It was the most reliable car I've ever owned right up until the day the HT4100 engine blew up at 86,000 miles and I had to scrap the car.

Other maintenance items it didn't NEED, but I had done because I loved the car:

- New thermostat

- Radiator drain and flush

- New spark plugs, wires, distributor cap and rotor

- Regular (2500 mile) oil changes

- New PCV and air filter and breather

- New brakes

- New tires.

Cosmetic repairs I made:

- Rolls-Royce grille

- Limo-tinted windows

- New dashboard

- New hood ornament.

General Comments:

I know people say that with proper maintenance and care, these HT4100-equipped Cadillacs will last forever, but I don't think that is the truth. I knew about the problems with the 4100 and I took the appropriate steps: Radiator drain and flush, clockwork oil changes, etc., and my car still died on me. It never even showed signs of stopping or of future problems until the day it conked out.

I was driving to work and I heard a crunching, rough sound under the hood. In the split second it took for me to think "Hmm, that sounds bad, I should pull over and have a look," the car had died and I was drifting to the side of the road.

Other than that it was probably the nicest car I've owned yet. It gave decent fuel economy (15-22 mpg), it was extremely quiet, handled nicely, and got nice comments from everyone who saw it. The 252-cid V-8 was extremely underpowered for the size of car it was pulling, and it took awhile for the car to accelerate in situations like getting onto the Interstate. Once the car got up to speed, however, it rolled from 45 MPH and up without a hitch.

It was painted in a very attractive dark blue/black metallic color called "Twilight Blue Metallic." The interior was blue leather. It had excellent legroom and an attractive dashboard which made navigation easy. It even had a factory cassette tape deck!

This car really broke my heart. I used to spend hours cleaning and detailing the car and keeping it in tip-top shape. It died anyway. I tried selling it to someone who could afford to put a new engine in, but to no avail. I didn't have the $2000 it would have cost, so I had it towed to the scrap yard. I watched them crush it.

If I could tell a prospective HT4100 owner one thing, it would be this: Buy the car if you want it, enjoy it while you can, but don't get too attached, because you never know when the end is going to come.

Would you buy another car from this manufacturer? Yes

Why did you not just put a chevy engine in. They're all the same and 200 bucks gets you a 350ci. At least here it does.

First, I think you severely underestimate the ht4100 they had their problems, but I have heard quite a few good comments about them.

Second, You should have kept the car until you could have bought either a new ht4100 or other compatible engine I have heard that the caddie 4.5 and 4.9 are compatible and are more reliable the 4100. It breaks my heart that you had such a nice car crushed.

1982 Cadillac Deville Sedan 4.1 liter V8 HT4100 from North America

Summary:

Move over Japanese crap, this caddy is one sweet ride

Faults:

My front brake pads needed replacing.

The right rear turn signal globe was cracked and had to be sealed.

The power antenna ceased to function years ago.

The trunk shocks no longer hold the trunk lid up.

General Comments:

Very big and hefty car. Weight and size being the true measure of a decent car.

Has that great smooth ride you can only get with a decent American car.

Power everything, obscenely soft seats are just a few of the luxury features. That gas mileage indicator and digital thermometer are pretty handy too.

I've got to agree with your comments. Cadillacs and most imports are in two different classes. You can't directly compare a Cadillac with, say, a Honda Civic. They're not meant to compete. I've owned three Cadillacs and I wouldn't have traded them for the world, but the most mileage I got out of one was 135k, while my girlfriend's Toyota Camry is at 200k and running strong.
