MOST COMMON PROBLEMS
CHEVROLET G-Series 1990
The 1990 Chevrolet G-Series is a versatile cargo van equipped with a powerful 5.7L V8 engine and hydraulic brakes. Manufactured by General Motors in Lordstown, Ohio, this 3/4-ton van features a 4x2 drive type and throttle body fuel injection. Ideal for heavy-duty tasks, it falls under Class 2E with a GVWR of 6,001 - 7,000 lbs. Notably, it can be converted to run on LPG.

Other Engine Info
LPG conversion can be accomplished on the engine.
Problems:
Brake fluid leaks
Hydraulic brake systems rely on fluid pressure to function. Leaks can lead to a loss of pressure and brake failure.
Worn brake pads/rotors
Regular wear and tear can cause brake pads and rotors to degrade, leading to reduced braking efficiency and possible damage to the brake system.
Vibration while braking
Warped rotors or uneven wear on brake pads can cause vibrations or pulsations when the brakes are applied.
Brake pedal issues
A spongy or soft brake pedal can indicate air in the hydraulic lines, while a hard pedal can point to problems with the brake booster or master cylinder.
Overheating brakes
Excessive use or heavy braking can cause the brakes to overheat, leading to diminished braking performance and potential damage to the brake components.
Brake warning light
If the brake warning light on the dashboard illuminates, it can indicate various issues such as low brake fluid, worn brake pads, or a problem with the brake system's sensors.
Engine misfires
V-shaped, 8-cylinder engines can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.
Oil leaks
Older engines, such as a 1990 model, may develop oil leaks around seals and gaskets, which can lead to reduced engine performance and potential damage.
Cooling system problems
V-shaped engines can have cooling issues, such as radiator leaks, thermostat failures, or water pump malfunctions, leading to overheating.
Timing chain/belt wear
If not replaced at recommended intervals, a worn timing chain or belt can cause engine performance issues or catastrophic engine failure.
Exhaust manifold cracks
V-shaped engines are prone to exhaust manifold cracks, which can cause exhaust leaks and reduced engine performance.
Lpg conversion issues
If the engine has been converted to LPG, potential issues can include improper tuning, fuel delivery problems, or component wear specific to the LPG system.
Fuel system problems
Clogged fuel injectors or a faulty fuel pump can lead to poor engine performance and reduced fuel efficiency.
Ignition system failures
Problems with the distributor, ignition coils, or spark plugs can cause starting issues and engine misfires.
