1996 Chevrolet S10 Problems
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
The serpentine belt tensioner can fail; it may become noisy and/or the belt may jump off. Replacement of the failed tensioner will be necessary.
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
On vehicles with intermittent windshield wipers, the wiper motor circuit board may fail and cause the wipers to stop working at times. Replacing the circuit board should resolve the issue. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.
A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.
A cover plate on the front of the engine may develop a coolant leak, resulting in an engine overheating condition. This plate covers the location where the water pump was installed on previous versions for this engine. Replacing the gasket for the cover plate and refilling the cooling system is generally all that is required to correct this concern.
hard starting after several hours and upon start up, engines missfires and runs rich
Possible fuel pump regulator failure under the upper intake leaking fuel directly into the intake system.
You must replace the regulator assembly and possibly the spider( injector cluster) to resolve the problem. Allowing the engine to run like this for an extended period could result in cylinder wall wash down resulting in internal engine damage.
