Jeep Cherokee XJ 1984

The XJ Cherokee introduced for the 1984 model year was the first Jeep with a ladder-boxed chassis integrated into a single monocoque unit rather than the traditional separate body-on-frame construction. The design was rigid and sturdy with approximately 3,200 welds in a completed body, "yet wonderfully lightweight, [the] Uniframe permitted outstanding performance even with AMC's new 2.5 L (150 cu in) four-cylinder engine."[22][23]

While the Wagoneer continued in production for another eight years as the Grand Wagoneer, the Cherokee nameplate was moved to a new platform for 1984. Without a traditional body-on-frame chassis, the Cherokee instead featured a light-weight unibody design.[5]

Products in this collection are for the 'XJ' Jeep Cherokee, sold in the US during the years 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, and 2001, as well as the 'MJ' Jeep Comanche pickup, which was sold between 1986, 1987, 1988, 1989, 1990, 1991, and 1992.

The 1984 Cherokee was the one to revolutionize the American SUVs, having a shorter wheelbase and a shorter length, thus being lighter a weighing 1000 pounds less compared to its predecessor. A pick-up version was also released and was named Jeep Cherokee Comanche.

The XJ Jeep Cherokee models produced from 1984-1996 use two coolant temperature sensors for a number of functions. Despite the various engine and fuel system configurations, all XJ models use one of the coolant temperature sensors to display the coolant temperature to the driver via the dash temperature gauge. The second coolant temperature sensor, often referred to as a "temperature switch," functions to maintain engine performance and proper emissions control. In addition to these sensors, certain models use an additional coolant temperature sensor to control operation of the electric cooling fan. Many owners often find their temperature gauge pegged in one direction, or is bouncing wildly and making the engine coolant temperature unreadable. Additionally, poor engine performance or smog related issues, especially in fuel-injected models, can sometimes be traced to a faulty temperature switch, because a failed switch is unable to relay the engine temp back to the ECU for proper fueling adjustments. Fortunately, coolant temperature sensors are some of the easiest items to replace and can restore function to your temperature gauge, or better yet, they can improve engine performance and driveability.

With Detroit-built car sales up sharply over a year ago, and with optimism high among automakers, the 1984 new-model caravan rolls into town. Motorists ask: Will it be the year of the rubber-burning performance car, the convertible, or the smaller car?

Launched by Chrysler Corporation some 18 months ago, the factory-sponsored ragtop is in the midst of a renaissance as Detroit car manufacturers follow in Chrysler's tracks with more and more open-to-the-wind cars. Even the General Motors Cadillac division, which a few years ago said the softtop would never return, brings back the open-top Eldorado for 1984.

The 1984 full-size Cadillac, for example, will be compressed by some two feet. More than a foot will be lopped off Ford's Continental Mark VII. The new mini-vans from Chrysler Corporation, due to hit the showroom early in the new year, will fit into the family garage. And American Motors has reduced the girth of its big Jeeps, the Cherokee and Wagoneer.

The Goodyear-developed air suspension, also used in the 1984 Continental, provides automatic three-way leveling for the luxurious Mark, no matter the weight. Whether the load is five passengers with luggage or a driver alone, the system adjusts the car's road clearance, both front and rear. 781b155fdc
