How to start Cadillac engine after sitting for 22 years

Ronnie Becnel’s question:

Hey, just got a 57 caddy that hasn’t been turned over in 22 years. What the best advice to prep engine before starting/turning the crank. Have you used Ultra one’s product in an engine block. Any advice is appreciated.”


OK, I’ve never used Ultra one, so I can’t give advice on that. BUT, since that baby has sat for SO long, do this: First, remove all the spark plugs. Then squirt some Marvel Mystery Oil (all auto parts stores and hardware stores sell it) into each spark plug hole. Then let it set for a couple of days. That stuff really loosens up rust and corrosion. Then get a new battery and crank the engine over with the spark plugs out. Hopefully it will crank over (though the starter motor may also be shot by now and you might have to put a new one on.) If the motor won’t turn over, then get a long cheater bar with a socket that fits on the end of the crankshaft in the middle of the harmonic ballancer. Try turning the engine over by hand. If you finally get the engine to spin, then spin it a while until the oil you put in the plug holes has splashed out. Then put in the spark plugs and prime the carburetor with a little gas and hope it fires up. good luck,

Is it worth buying 1967 Cadillac For Restoriation?

Arlene’s question:

My husband want to buy an old 67 Cadillac and fix it up. PLEASE give me some information I can use to talk him out of it. I don’t want another old car taking over the garage for years again.”


Well, he may have his mind set, but here goes: Getting parts for older Cadillacs can be an expensive pain, because the dealers stop stocking parts after eight years or so. The last customer I had who attempted such a feat spent untold thousands of dollars, and ended up eight years later selling the car at a BIG loss. You must realize that really restoring a car can cost ten to twenty thousand dollars, and unless the car is a REAL classic, you will never recoup your investment. Guys that buy classic cars are VERY picky about original equipment, and if any parts are aftermarket and not original, they won’t even give an offer for the car. So there’s a little bit of ammunition for your attempt to derail him.

1999 Cadillac Deville C1277 ABS Trouble Code

Julius’s question:

The traction control light flashes on and off in my 99 Deville. It had code C1277 when I had it scanned. Something about the ABS module. But the brakes feel fine to me. What should I do?


Yes, the ABS module costs a small fortune on that Cadillac. BUT, I fixed one last month with the same problem. It turned out the electrical connector on the ABS module had gotten corroded. So I unplugged the module and cleaned it out with spray electrical cleaner until the green corossion was gone. Then I applied dielectrical grease (which you can get at any auto parts store) to the connector before snapping it back together. So check that, because being under the hood, water can intrude on that connector and mess things up. Let’s hope it’s that and not a bad expensive ABS module.

Cadillac Deville 2000 Alternator Not Charging

Marcus’s Question: My 2000 Cadillac Deville stopped charging and went dead. I had the battery and alternator replaced, but the alternator still won’t charge the battery. The guys at Auto Zone checked the alternator on their machine, and it works fine. So it’s got to be something feeding the alternator. What should I check next?



Answer: Yes, you’ve got a stinker on your hands. SO, check all the wiring going to the alternator to make sure none are burned or loose. Of course, check the fuses to see if any are burned. Hopefully it’s something simple like that. BECAUSE in that Caddie, the alternator is ultimately run by the main computer, and are they Expensive. Occasionally I see one go bad and have to be replaced because the alternator would no longer charge. Let’s hope it’s just a broken wire somewhere instead.


Cadillac CTS 2004 Broken AC Knob

Freddy’s Question: The AC knob on my 2004 Cadillac CTS has broken off. I tried super gluing it back on, but it won’t hold very long before it breaks off again. Am I going to have to buy the whole expensive control unit?


Answer: No, you won’t have to buy that VERY expensive entire control unit just because the knob has broken. So many of those knobs have broken that the Caddie dealers now sell just the knobs themselves. SO, you might just mosey over to a dealer and buy a couple. Keep one as a spare in the glove box.
