The 1980 GMC Jimmy was built tough, with a full-frame design and solid axles that made it one of the most capable off-roaders of its time. Whether you’ve got the 350 V8 or the legendary 6.2L diesel, keeping your Jimmy in top shape means maintaining brakes, suspension bushings, and weatherstripping—all common weak spots after decades of use. One thing Jimmy owners know? Rust is the enemy. If your rocker panels, fenders, or floorboards are looking rough, it’s time for some fresh sheet metal. And if your engine is running hot, check your radiator and cooling system hoses—old rubber tends to crack and leak.
