When the engine has cooled down check the coolant level and make sure it is full. If the coolant is in the operating range, I would suspect one of two problems, water pump or thermostat. With the engine on check to make sure the serpentine belt (should be only one belt for your engine) is turning the pulley for your water pump is rotating without restriction.
The thermostat will allow coolant flow when it reaches operating temperate. You may be able to squeeze the hose and feel the pressure of the water flow when the engine is heating up. Be careful of loose fitting clothes and your body stays away from moving parts of the engine. If you have no flow check the thermostat first and if the flow of coolant is not circulating when the engine warms up you will have to drain the coolant to remove the pump to check the operation and replace if necessary.
The thermostat is inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. Follow the large radiator hose to the engine block. The hose connects to a cast iron elbow with two bolts holding it to the block. Drain the radiator fluid, unbolt the two bolts and you should see the thermostat. Clean off the old gasket off the block and elbow then bolt the elbow and new thermostat with gasket to the block to the manufactures torque specs. I would buy some radiator flush if it has not been flushes for several years. Fill the radiator with the correct ratio of coolant and water replace the cap then run the engine for 15 minutes and look for leaks or listen for hissing from the leaks.

SOURCE: How to put front breaks on a 1999 chevy automatic cavalier

Place the bike on a stand, disconnect the cable, remove the wheel, set the wheel brake side up, use the bolt slightly inserted in the drum, or two oposing screw drivers around the drum to pull it from the wheel. Once pulled, remove the springs and shoes,lightly sand the inner drum on the wheel, install new pads and springs, spray both drums with brake clean, reassemble drums and wheel, install the wheel, and then adjust cable tension and brake pressure at first the wheel, and then at the bars. Test and readjust as needed.

SOURCE: I have 1999 chevy cavalier. My ABS light is oh.

Drive it. Then have the rear abs brake sensors checked because they seem to be the first to go in a system like that. Someone with a scan tool should be able to read out any trouble codes in the abs system

SOURCE: where is the iat sensor located on a 1999 chevy cavalier 4cyl

The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Fig. 1: The IAT sensor is located in the air cleaner outlet tube-2.2L engine and 2.4L engine

Hope helped.

Engine over heated and will not start


Did you have oil in it. depending on the severity of the overheat you may have seized the engine. You also could have a head gasket problem. The cooling system on these little cars can overheat in heavy traffic and going up a hill a little too fast. Solution? If it started and showed white smoke out of the exhaust. Head Gasket. If it won't turn over with the starter it's seized. Both will cost a mint. If you had no oil engine could now be junk.
