Question about 2002 Chevrolet Cavalier Coupe
It is most likely the Heater Valve which is very common on this car.
While at first glance, replacement of the valve looks difficult. But in reality the valve can be removed in 20 minutes with no special tools and requires little disassembly.
1. Remove both windshield wiper arms.
2. Remove the cowl cover that covers the cabin air filter. This includes the left side. There are two clips on the passenger side and a torx screw on the driver's side. Under the lower windshield rubber molding you will find a series of what looks like plastic screws but are fasteners and only require a quarter turn and a pull up to remove. This will all allow you to remove the complete cowl cover.
3. Remove the passenger cabin filter and the bracket that holds the filter. There are two vacuum lines and two plastic nuts holding it in place. You will have to maneuver the filter holder to get it out but not a hard thing to do. Once this is out the rest is cake.
4. You will see an access door held in place by the same size plastic nut that held the cabin filter. Remove that and you will have all the access to the heater control valve you need.
5.The heater control valve had no hold down bracket and was held in place only by the hoses connected to it. Remove the vacuum hose. The water hoses have the compression type clamps on them Use a nine-inch pair of channel locks to remove the clamps (they give you the reach you need) from the valve while holding the valve with the other hand placed through the access door. After all the clamps are moved from the valve, remove the hoses. You may need a small screwdriver to push between the hose and valve out to free the hose. After all the hose are removed simply remove the valve through the access door. Reverse procedure to reinstall valve.
***I would suggest replacing the compression hose clamps with the screw type.

The coolant could be getting into your oil, or it could be going out the exhaust from a blown head gasket or a cracked head you will probably be able to smell a sweet smeel near the exhaust if its being burned...

Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top.
Fill the overflow/coolant reservoir with the same 50/50 mixture.
Leave the radiator cap off, turn the engine on and let it run until the radiator "burps": You will see the coolant level drop and may see or hear a large air bubble come to the top as the system burps.
Keep an eye on the temperature gauge throughout this process.
Refill the radiator to the top and coolant reservoir as needed.
Put the radiator cap back on.
