The Chevrolet Van or Chevy Van (also known as the Chevrolet/GMC G-series vans and GMC Vandura) is a range of vans that was manufactured by General Motors from the 1964 to 1996 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier, the model line also replaced the panel van configuration of the Chevrolet Suburban. The vehicle was sold both in passenger van and cargo van configurations as well as a cutaway van chassis that served as the basis for a variety of custom applications.

Produced across three generations (1964–66, 1967–70, and 1970–96), the model line was sold under a wide variety of model names under both the Chevrolet and GMC brands. The first two generations were forward control vehicles (with the engine placed between the seats); the third generation adopted a configuration placing the engine forward of the driver. The second and third generations shared powertrain commonality with the C/K pickup truck model line.

After the 1996 model year, GM retired the G-Series vans, replacing them with the GMT600-platform Chevrolet Express and GMC Savana.

Intake Manifold Gaskets May Leak Coolant or Engine Oil

One of the most common issues with the Chevrolet G20 1983 is the intake manifold gaskets, which may leak coolant or engine oil. This problem can cause the engine to overheat or lose power, and it can also lead to a decrease in fuel efficiency. The intake manifold gaskets are located between the engine block and the intake manifold, and they are responsible for sealing the engine's cooling system and fuel system. If the gaskets become worn or damaged, they can leak coolant or engine oil, which can lead to serious engine problems.

Transmission Cooling Lines May Rub Through and Leak Fluid

Another common problem with the Chevrolet G20 1983 is the transmission cooling lines, which may rub through and leak fluid. This problem can cause the transmission to overheat and fail, which can be a costly repair.

Fuel Pump May Have an Open Circuit or Bad Fuel Pump

The fuel pump is another common problem area for the Chevrolet G20 1983. The fuel pump is responsible for delivering fuel to the engine, and if it has an open circuit or a bad fuel pump, it can cause the engine to crank but not start.

Carburetor May Have Debris Particles or a Vacuum Leak

The carburetor is another common problem area for the Chevrolet G20 1983. The carburetor is responsible for mixing fuel and air, and if it has debris particles or a vacuum leak, it can cause a rough idle or dying at idle.
