Is the GMC C3500 some kind of crossover or combination vehicle? What kind of engine muscle complements a commercial vehicle this tough?
In 1991, General Motors introduced the C3500HDunder the Chevrolet and GMC nameplates.The C3500HD was a 15,000-pound GVW (Gross Vehicle Weight) truck that was only offered as a commercial chassis cab. In 1996, the manufacturer presented crew cab versions of the vehicle. The extended cab, 4-wheel drive configuration was never offered to the public.
The GMC C3500HD was equipped with a 5.7L, 7.4L, and the 6.5L turbo diesel. The only two transmission packages ever used for a C3500HD were the 4L80E 4-speed OD automatic and the NV4500 5-speed OD manual
The GVW rating of these trucks was 15,000 pounds.The wheelbases available were 135.5 inches, 159.5 inches, and 183.5 inches. They had similar but upgraded designs to theC3500 cab and chassis.
My truck surges or loses speed when I mash the gas pedal above 55 miles per hour? Why is this so?
These appear to be classic symptoms of a restricted or dirty fuel filter or a defective fuel pump.Experts recommend replacing both just to be sure, and then test then fuel pressure with a test gauge.
What is going on when my idle is higher than usual?
An engine vacuum leak may develop from the throttle body gasket, causing the engine to idle higher than normal. Defective gaskets should be replaced.The throttle body gasket is gasket made of paper or aluminum that is sandwiched between the throttle body and the intake manifold. It is meant to provide an airtight seal between these components so that incoming air cannot bypass the throttle body. This gasket is often replaced during a throttle body service.
My A/C is making abnormal noises. What could be the cause of this? What should I do about a burning smell coming from my engine?
The only solution for a noisy air conditioning compressor is replacement. Experts recommend that a filter kit should be installed to prevent any metal particles in the system from damaging the new compressor.
The cause of the smell could bean oil leak in the valve cover gaskets. A solution to this problem is to reseal the valve cover. However, the valve covers should be inspected and immediately replaced if damaged.
My truck isn't drivable at all. What's going on? Why is my truck's automatic transmission shifting erratically?
The distributor may have developed internal faults. This can cause a rough running, engine stalling, and the Check Engine Light may or may not illuminate. Experts have pointed out that the vehicle's distributor should be overhauled or replaced to address this concern.
Transmission fluid may have leaked through the electrical connector on the side of the transmission, damaging the wire harness and causing the erratic transmission shifting. According to experts, there are updated shift solenoids, an internal transmission harness, and a connector pigtail available to address this issue.
