1987 Chevrolet G20 problems
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 1987 Chevrolet G20 problems
The Chevrolet G20, introduced in 1987, is a popular full-size van known for its spacious interior and reliable performance. However, like any vehicle, it is not immune to certain common problems. This article will explore some of the most frequently reported issues with the 1987 Chevrolet G20, based on complaints from owners and online discussions.
1. Intake Manifold Gaskets May Leak Coolant or Engine Oil
One of the most common problems with the 1987 Chevrolet G20 is leaking intake manifold gaskets. These gaskets can deteriorate over time, leading to leaks of coolant or engine oil. This issue can cause a decrease in engine performance, increased fuel consumption, and potential engine damage. In some cases, the leaks can be so severe that they cause the engine to overheat, potentially leading to catastrophic engine failure.
2. Fuel System Problems
Fuel system problems, particularly with fuel injectors and pumps, are another common issue with the 1987 Chevrolet G20. These problems can manifest as a lack of power, hesitation, or stalling during acceleration. In some cases, the engine may not start at all. Fuel system problems can be caused by a variety of factors, including worn-out or clogged fuel injectors, faulty fuel pumps, or issues with the fuel pressure regulator. These issues can lead to poor engine performance, increased fuel consumption, and even complete engine failure if left unaddressed.
3. Engine Knocking and Hesitation
Engine knocking and hesitation, particularly under low RPM acceleration, are also common problems with the 1987 Chevrolet G20. These issues can be caused by a variety of factors, including faulty or disconnected EGR valves, bad throttle position sensors (TPS), or timing issues. Engine knocking can cause significant damage to the engine over time, while hesitation can make the vehicle difficult to drive and lead to decreased fuel efficiency. In some cases, these issues can be resolved with simple repairs, such as replacing the EGR valve or TPS. However, in more severe cases, the engine may require more extensive repairs or even replacement.
4. Transmission Issues
Transmission issues, particularly with the automatic transmission, are also common with the 1987 Chevrolet G20. These issues can include difficulty shifting gears, slipping, or complete transmission failure. Transmission problems can be caused by a variety of factors, including worn-out or damaged transmission components, low transmission fluid levels, or faulty solenoids. These issues can lead to decreased fuel efficiency, difficulty driving, and even complete engine failure if left unaddressed.
5. Rust and Wear Issues
Rust and wear issues are also common with the 1987 Chevrolet G20. These issues can include worn-out or damaged hinges, rust issues, worn-out transmissions (if abused), and front-end wear. These issues can lead to decreased vehicle performance, difficulty driving, and even complete vehicle failure if left unaddressed. Regular maintenance and inspections can help prevent these issues from becoming more severe over time.
In conclusion, the 1987 Chevrolet G20 is a reliable and capable vehicle, but like any vehicle, it is not immune to certain common problems. By staying aware of these issues and addressing them promptly, owners can help ensure their G20 remains a reliable and capable vehicle for years to come.
