How to remove the heater core the easiest way from a Cadillac Deville 2001

Backfiring smell strong gas muffler blowing out muffler

It's starts overheating when I drive but doesn't do it when ideling running for a hr with the heat on high. I just changed water pump, thermostat, upper hose, last month and the radiator was changed last yr. DID THE BLOCK AND HEADGASKET TEST. ALL WAS GOOD. ( I'm thinking the thermostat was put in wrong or could the radiator be clogged or that lower hose?) The fans come on and are working when they suppose too.

I have a cadillac deville d'elegance 98, i have put a new computer system in it, 2 alternators and 2 new batterys but my battery still wont hold a charge and its sayin charging system error still.someone please help me ive had it for a year and only drove it for a month

Heater starts when dash
over glove box is hit!

leaking powersteering fluid under the driver dash bored inside the car

Replaced water pump radiator and thermostat and the car still wants to run hot

No leaks under car when parked. Do fill with antifreeze.

already got new key,ignition turns over won't engage,dash lights like crazy possible ignition switch or antitheft system?

So my battery died one day and i got a jump. When i did that my alarm started going off. I can start the car still but the horn sounds and all the start flashing. Can anyone tell me how to disarm it?

And dadhboatd vents no air flow but vents in back seat work. Help

rear shock compressor making loud noise while running and then shuts off. had an estimate of 900.00 to repair. reasonable??

Possible Heater core? How do I narrow down cause? This is constant doesn't change.

When I depress the brake it wasn't responding, checked the lines at the wheel, no flow of fluid

Acts like a fuel problem by rough running especially up hills. Speed odometer jumps around when it does this has even died twice while going down the road at slow speeds but started right back up. Also rough shifting when this happens.

check next and how?

Vehicle shuts off when I come to a stop. No warning lights. Vehicle will start back up, but drive to next stop light and vehicle shuts off again. Issue happens approx. after driving 1or 2 miles.

Sometime it runs great but most of the time seems to be a little rough with more noise than normal. Not a miss just less performance and not smooth or quiet like before ECM went out. Is the 2001 ECM I used the problem? Could it be one or more bad coils? Limited income so I have to fix it myself.

How do I resolve these problem codes P039 Converter clutch engagement problem P052 PCM memory reset I039 Loss of Road Sensing suspension data I052 Keep alive memory error, Or can I just reset

Some days may drive good idle around 600.

Abs and traction light on cost to repair. Just had hub bearings replaced aND front roots and brakes.

When I turn on my heater.it blows cold one side hot other side.

vents on the right and left sides?

Electronic Fuel gauge dosen't work and My car vibrates at high speeds

Its not bose so how can i properly do that

Where is the relay? What else should I check?

It's two months now since the engine bay was washed on my 90' Cad. and it still idles and surges to much to drive safely. Why isn't there a mechanic that can figure out what electrical component got wet. Ten mechanics and none of them know anything !
