The Cadillac Deville, whose name is derived from the French term "de la ville" or "of the town," is a venerable eight-generation luxury car line from the brand. Initially designed as a pillarless two-door vehicle accommodating 5-6 passengers without any division, the Deville was first showcased at the 1949 General Motors Motorama. Notable for its chrome trim around the front wheel opening, a false air scoop, and one-piece windshield and rear glass, the Deville combined exterior sophistication with an elegant interior of gray leather trimmed in black. Over its long history, the Deville evolved significantly. In 1955, it expanded its offering to include both coupe and sedan body types, adding versatility to its range. This move helped cement its position in Cadillac's main luxury car series. The latest iteration, released in 2000, was based on a K-body platform and powered by a 4.6L Northstar V8 engine paired with a 4-speed automatic transmission. The 2000 model showcased a smoother, aerodynamically friendly design, LED taillights, a power rear window sunshade, heated rear seats, a stability control system, and GPS. Of special note is the popular night vision system that uses a passive infrared sensor camera to detect infrared radiation, which is processed and displayed on the windshield through an automotive head-up display. This affordable, versatile system has been widely installed even in other models. The Cadillac Deville, therefore, represents a blend of classic luxury and advanced technology, carrying forward the brand's legacy of sophistication and innovation.

Despite its development over nearly five decades, the Cadillac Deville is not without its shortcomings, particularly as usage time increases. A prevalent issue among Deville owners is an engine problem characterized by excessive oil consumption, noticeable oil smells while driving, oil leaks, and strange noises. Defective components such as the spark plug, timing chain, and timing chain tensioner may cause poor fuel economy, engine misfires, and difficulty starting, so owners are advised to inspect these parts if experiencing similar symptoms. Another common issue is overheating and antifreeze leaks. Indications of this problem include rising cabin temperatures, less effective air conditioning, loud noises when the compressor is running, and a stationary compressor, signaling a failing A/C compressor that needs replacement. Additionally, even less conspicuous parts like the wheel cover and antenna, which serve decorative and functional purposes respectively, require attention to ensure overall vehicle performance and a pleasant driving experience.

Choosing OEM parts is the best decision for guaranteeing superior quality and perfect performance. These components undergo stringent quality checks and are carefully constructed to comply with Cadillac's factory specifications, ensuring a smooth installation process.

Cadillac Deville Parts Questions & Answers

  • Q: How do you remove the coolant reservoir or expansion tank?
    A: To remove the coolant reservoir or expansion tank, start by draining the cooling system and removing the radiator support cover if necessary. Then, detach the hose from the top of the expansion tank and remove the radiator support brace and cross-vehicle brace if equipped. Disconnect the coolant level sensor connector and remove any relay mounting brackets or fuse/relay panels that may be in the way. Loosen the clamp from the lower hose and remove it. Finally, remove the mounting bolts or nuts and pull the coolant reservoir or expansion tank straight up and out of the vehicle. To install, clean the inside of the reservoir, scrubbing hard-to-reach areas with hot, soapy water and rinsing with clean water. Then, follow the reverse steps of removal and refill the cooling system if necessary.
  • Q: How do you remove the blower motor on Cadillac DeVille?
    A: To remove the blower motor on a 1999 model (except Seville), start by disconnecting the cable from the negative terminal of the battery. Then, remove the strut tower cross brace, if equipped, and the bracket from the relay center. Position the relay center and MAP sensor off to the side, and remove the ignition coil assembly and solenoid purge valve, if equipped. Cut the rubber insulator and remove the metal patch plate from the engine compartment, and remove the inertial plate from the blower motor case. Disconnect the wiring connector and cooling hose from the blower motor, and remove the mounting screws to pull the blower assembly out of the housing. If there's not enough room, angle the blower motor to unscrew the nut on the fan and remove the motor and fan separately.
  • Q: How do you remove the ignition coil assembly on Cadillac DeVille?
    A: To remove the ignition coil assembly, start by disconnecting the negative battery cable and removing the intake manifold service cover. Then, disconnect the electrical connector from the ignition control module and remove the radiator support cover, moving the radiator hose out of the way. Next, remove the ignition coil assembly bolts in the indicated sequence and take out the assembly from the valve cover. Inspect the spark plug boots for carbon tracking and deterioration. When installing the ignition coil assembly, tighten the mounting bolts gradually and evenly. For the rear ignition coil assembly, follow the same steps but also remove the Air Injection Reaction (AIR) vent solenoid. If replacing the ignition control module, tighten the mounting bolts in the indicated sequence. Finally, install the AIR vent solenoid and reverse the removal process for installation.
  • Q: How to replace a thermostat in a cooling system?
    A: To remove the thermostat, disconnect the cable from the negative terminal and drain the cooling system. Loosen the hose clamp and remove the hose from the thermostat housing, or the thermostat housing cover with the radiator hose attached if the clamp cannot be accessed and remove the thermostat cover mounting bolts and detach the housing cover.
