Newest reported 1990 Chevrolet S10 problems
The metal brake line corroded away, and without warning failed completely. My truck was built in 2002 and during that time GM did not use stainless steal for the brake lines. Living in PA, we use salt on our roads during snow events. This salt corrodes away the non stainless steal break lines. If you have a GM vehicle made from 1999-2003, check to see if the SS was OEM spec. If not, have your shop check for any corrosion along the brake lines ...
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
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.
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.
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.
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.
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.
The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
