Two of the trucks manufactured by Chevrolet in 1994 were the C1500 and the S-10. The regular cab C1500 came equipped with a 4.3 liter six cylinder engine and included many different standard features such as air conditioning, 15-inch wheels and power steering. The base trim of the 1994 S-10 had a 2.2 liter four cylinder engine and came with power brakes, rear wheel anti-lock brakes and cloth seating. Because the C1500 and S-10 are made of so many different parts it can be difficult to troubleshoot problems with these trucks. One way to determine what is wrong with the truck is to examine recall information issued by Chevrolet.
Look at the oil filter of your truck when you see oil leaking underneath the engine. You may have installed a defective aftermarket filter that was manufactured by Fram. The Fram oil filter gasket becomes pliable under hot temperatures and pressures and may not seal properly to its engine connection point. This will allow oil to leak out into the engine and, if it combines with an ignition source, start an engine fire. Replace the oil filter to avoid this result.
Examine the fuel filter of your truck if you see fuel leaking underneath the engine of the truck. The filter may have been manufactured by Honeywell and does not meet Chevrolet's specifications. Consequently, the fuel filter O-ring may not seal correctly around the truck's fuel line and allow gasoline to leak out into the engine. If the fuel comes into contact with the proper ignition source a fire may erupt in the engine. Change the fuel filter to keep this from happening.
Check the steering shaft of your truck if the front wheels do not respond properly to the driver's turning of the steering wheel. The upper and lower bolts on the steering shaft that hold the steering gear coupling to the shaft may have come loose. When the bolts are loose the yoke pinch bolt can wear on the splines of the steering shaft until there is no longer a connection between the splines and the bolt. This can cause the steering gear to separate from the steering shaft and render the steering wheel inoperative. Take your truck to a local Chevrolet dealership to have the upper and lower bolts on the steering shaft re-torqued to the proper specifications.
Inspect the fuel tank filler tube pipe if you see gasoline leaking underneath the rear portion of the vehicle. The connection between the filler tube and the gas tank may not be secure and is allowing gasoline to leak out each time you gas up your truck. A fire could occur in your fuel tank if this condition persists. Replace the fuel tank filler tube to resolve this problem.
