Question about 2001 Chevrolet Cavalier
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
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.

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.

Well the biggest problems for the 98 and 99 cavaliers are that they mess up from the timing chain,..they make a rattling noise on the right side underneath the fender.

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

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
