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.

Common 1986 Gmc G2500 problems

The GMC G2500 from 1986 is a popular choice for van enthusiasts, but it is not without its common problems. One of the most frequently reported issues is idling problems due to vacuum leaks in the throttle body gasket. This problem can cause the engine to run rough or stall, especially during slow-moving traffic or at idle. The throttle body gasket is responsible for sealing the throttle body to the intake manifold, and over time, it can wear out or become damaged, leading to vacuum leaks.

Another common problem with the 1986 GMC G2500 is related to the fuel system. Some owners have reported issues with the fuel pump relay, making it difficult to find the fuel. This can lead to starting problems or intermittent running issues. It is essential to locate the fuel pump relay and ensure it is functioning correctly to prevent these issues.

The windshield wiper motor is also a common problem area for the 1986 GMC G2500. Some owners have reported issues with the windshield wiper motor, which can lead to the wipers not working correctly or not working at all. This can be a significant safety issue, especially during inclement weather.

The interior lights are another problem area for the 1986 GMC G2500. Some owners have reported issues with the interior lights, such as the dashboard lights not working or the interior lights not turning on. This can make it difficult to see the instruments and controls at night or in low-light conditions.

The 1986 GMC G2500 can also experience issues with the throttle position sensor. Some owners have reported issues with the throttle position sensor, which can lead to rough running or stalling, especially during cold starts or at idle. The throttle position sensor is responsible for providing the engine control module (ECM) with information about the position of the throttle plate, and a faulty sensor can cause the ECM to make incorrect fuel and ignition adjustments.

The 1986 GMC G2500 can also experience issues with the fuel pressure regulator. Some owners have reported issues with the fuel pressure regulator, which can lead to a rich condition and poor fuel economy. The fuel pressure regulator is responsible for regulating the fuel pressure in the fuel system, and a faulty regulator can cause the engine to run too rich, leading to poor fuel economy and increased emissions.

In summary, the 1986 GMC G2500 is a popular choice for van enthusiasts, but it is not without its common problems. Idling problems due to vacuum leaks in the throttle body gasket, issues with the fuel pump relay, problems with the windshield wiper motor, issues with the interior lights, issues with the throttle position sensor, and issues with the fuel pressure regulator are all common problems reported by owners of this vehicle. It is important to address these issues promptly to ensure safe and reliable operation of the vehicle.
