Mercury Grand Marquis, a product of the defunct Ford Motor Company division, Mercury, was a renowned model sold from 1975 to 2011 across four distinct generations. The vehicle debuted in 1967 as a two-door hardtop, with notable features such as a wood-trim steering wheel and leather-and-velour split-bench seats. The Grand Marquis introduced a V8 engine, with an option for 4-wheel disc brakes. To enhance fuel economy, it adopted a 400 cubic-inch V8 as its standard engine. The first generation, beginning in 1979, saw the Grand Marquis becoming lighter and shorter, yet it retained its basic suspension design and incorporated gas-charged absorbers. The year 1985 saw the installation of a four-speed AOD automatic overdrive transmission. Offered in both two-door and four-door versions, the Grand Marquis featured a standard half-length vinyl and a full-length roof. It made strategic changes like replacing steel bumpers with aluminum ones for weight reduction and underwent two major revisions of its interior auto parts, including an updated dashboard with an added temperature gauge alongside the fuel gauge. Initially serving as the luxury model in Mercury's lineup from 1975 to 1982, it became a standalone model in 1983. Manufactured at two facilities, the Grand Marquis was primarily sold in North America and the Middle Eastern market. Over its long production period, the Grand Marquis remained committed to performance upgrades, contributing to its sustained appeal.

Mercury Grand Marquis, like any vehicle, can experience wear and associated issues over time. Identifying and resolving these problems can slow the wear process and extend the vehicle's lifespan. Electrical problems are common in many modern vehicles, including the Grand Marquis. Complaints often include issues with the heater not functioning properly or getting stuck at a certain speed, as well as potential blockages in the blower motor. Checking the blower motor and blower motor resistor is recommended in such instances. Transmission and suspension system failures are also reported problems. Symptoms of transmission issues may include clutch slippage, the vehicle halting unexpectedly, delayed reversing, and strange noises. Suspension failure often presents as sluggish handling response and persistent rattling or squeaking noises emanating from the vehicle's underside. It's advised to inspect the sway bar link bushing and automatic transmission filter first when these issues arise. Maintaining clear visibility is vital for safe driving, which largely depends on the proper functioning of the windshield wiper system, especially the wiper pivot and wiper arm. Regularly checking these components, along with the wheel cover, which helps prevent accumulation of dirt and moisture on wheels, is essential for safe and smooth vehicle operation.

These components are directly manufactured by Mercury, adhering to stringent factory guidelines, and are subjected to rigorous quality control procedures during production.

Mercury Grand Marquis Parts Questions & Answers

  • Q: How to inspect and replace battery cables on Mercury Grand Marquis?
    A: Inspect battery cables for damage like cracked insulation and corrosion. Check cable-to-terminal connections for cracks, loose strands, and corrosion. White deposits under the insulation indicate corrosion and need for replacement. Check terminals for distortion, missing bolts, and corrosion. When replacing, disconnect the negative cable first and connect it last to avoid shorting. Even if only replacing the positive cable, disconnect the negative first. Ensure the replacement cable is the same length and diameter. Clean the relay or ground connection threads with a wire brush and apply petroleum jelly to prevent corrosion. Attach the cable and tighten the nut/bolt securely. Before connecting to the battery, ensure it reaches the post without stretching. Clean the battery posts and apply petroleum jelly to prevent corrosion. Connect the positive cable first, then the negative.
  • Q: What is the purpose of the catalytic converter in the exhaust system on Mercury Grand Marquis?
    A: The catalytic converter is an emission control device added to the exhaust system to reduce pollutants from the exhaust gas stream. A single-bed converter design is used in combination with a three-way (reduction) catalyst. The catalytic coating on the three-way catalyst contains platinum and rhodium, which lowers the levels of oxides of nitrogen (NOx) as well as hydrocarbons (HC) and carbon monoxide (CO). The test equipment for a catalytic converter is expensive and highly sophisticated. If you suspect that the converter on your vehicle is malfunctioning, take it to a dealer or authorized emissions inspection facility for diagnosis and repair. Whenever the vehicle is raised for servicing of underbody components, check the converter for leaks, corrosion, and other damage. If damage is discovered, the converter should be replaced. Because the converter part of the exhaust system, converter replacement requires removal of the exhaust pipe assembly. Take the vehicle, or the exhaust system, to a dealer or a muffler shop.
  • Q: What is the purpose of the EGR system and EGR Valve on Mercury Grand Marquis?
    A: The EGR system reduces NOx emissions with two different systems. The Electronic Exhaust Gas Recirculation and the Pressure Feedback EGR. The EGR valve is controlled by a solenoid and the PCM. To check, perform a leakage test and clean the ports. The system uses an Electronic Vacuum Regulator to control exhaust gas flow. Check the voltage and resistance of the regulator and the EGR valve position sensor and replace it or regulator if needed.
