The Cadillac Fleetwood is a luxury vehicle produced by Cadillac from 1976 to 1996, following its initial introduction as a prefix for several Cadillac models post-1935. Characterized by a longer wheelbase than other common models, the Fleetwood transitioned from rear-wheel drive to front-wheel drive in 1985, with the rear-wheel version still in production until 1992. A new rear-wheel-drive Fleetwood was launched in 1993 and ran until 1996. Between 1985 and 1993, the Fleetwood models were built on the front-wheel-drive C-body platform, featuring an initial 4.1 L HT-4100 V8 engine which was later replaced with 4.5 L HT-4500 and 4.9 L HT-4900 engines, increasing the output from 180 to 200 hp. All these models came with a 4-speed automatic transmission. In 1993, the Fleetwood name was designated to the revised rear-wheel-drive D-body, making it one of the first American front-wheel-drive vehicles to revert to rear-wheel drive. It was the longest production car sold in the US at the time, measuring 225 inches. From 1993 to 1996, the commercial edition of the model served as funeral coaches and limousines, replacing the DeVille. Notably, the Fleetwood was discontinued in 1996, along with all other rear-wheel-drive sedans. With genuine Cadillac Fleetwood parts, the car boasts a 121.5 inches wheelbase, a length of 225 inches, a width of 78 inches, and a height of 57.1 inches, making it a standout model in Cadillac's history.

Despite its luxury status and state-of-the-art components, the Cadillac Fleetwood isn't immune to natural wear and tear. Two key issues are prevalent: cooling system failures and problems with the braking and suspension systems. Owners have reported frequent engine overheating and significant coolant level drops in the Fleetwood's cooling system, often necessitating constant coolant additions. Leaked coolant is another tell-tale sign, pointing to the need for a thorough check-up or possible replacement of the radiator and coolant reservoir. For the braking system, drivers have experienced difficulty pressing the brake pedal and increased stopping time, sometimes accompanied by fluid leaks. These issues warrant a comprehensive inspection of the brake booster. Suspension system failures often trace back to a faulty wheel bearing. To extend the lifespan of the Cadillac Fleetwood, special attention should be paid to often overlooked parts such as the emblem, which can fade due to exposure to elements and the door handle that wears out over time. Timely replacement of these components can enhance both the vehicle's aesthetics and operational safety.

Cadillac Fleetwood Parts Questions & Answers

  • Q: What does the Manifold Absolute Pressure (MAP) sensor measure?
    A: The Manifold Absolute Pressure (MAP) sensor measures changes in intake manifold pressure, which is the difference between barometric pressure and manifold pressure. It helps the PCM adjust for different altitudes and controls fuel delivery and ignition timing. The PCM sends a 5 volt reference signal to the MAP sensor, and by monitoring the sensor output voltage, it can determine the manifold pressure. Testing involves comparing the voltage reading to a chart, backprobing the MAP connector, applying vacuum to the sensor, and checking the voltage between terminal C and ground. If the sensor and circuits are functional, the PCM may be faulty. To remove the MAP sensor, the intake manifold top cover is removed, the crankcase breather tube is disconnected, and the sensor is detached from the intake manifold. The MAP sensor grommet should be inspected and replaced if necessary. Installation is the reverse of the removal procedure.

Remove the MAP hose from the throttle body and the right side spark plug wires and conduit. Remove the fuel vapor canister pipe bracket and drain the cooling system. Remove the heater hose and brake booster vacuum hose from the intake manifold. Then, remove the rocker arm cover, gasket seals, rocker arms, and rocker arm support. Clean the gasket mounting surfaces and inspect for wear or damage. To install, lubricate the parts with clean engine oil and use a new gasket with RTV sealant. Install the rocker arms and pivots, tighten the pivot bolts, and place each pushrod into the rocker arm seat. Install the rocker arm support, retaining nuts and bolts, rocker arm cover seals, and rocker arm cover. Connect the brake booster vacuum hose and spark plug wires. Install the air management and bracket assembly, replace the heater hose and air cleaner assembly, and connect the negative battery cable. Finally, start the engine and check for leaks.
