U will have to jack the front of the car up and crawl under, it is on the inside of the driver side rad tank or the pass side (varies from year to year)., it is a plastic valve the head of it looks like a clock key, careful not to break it, if u do you will need a new radiator tank installed. the valve loosens counter clockwise.

Heater core

Has the car overheted ? If so did you install the thermostat ? Check the coolant level. Low coolant level causes the car heater to not work. Also always bleed the cooling system everytime you add coolant when doing work on a car's engine. They have a bleeding screw near the thermostat housing or on the housing itself. After getting the engine to operating temperature, turn that little screw counter clockwise. This will release the pressure in the cooling system. Keep it open until only coolant comes out. If you cannot find a bleeding screw, do not open the radiator cap. But slowly turn the cap until you hear the coolant start flowing into the coolant reservoir .

Cutlass supreme oldsmobile 1990 running hot

Check to see if your electric radiator fan is turning on. These cars are known for the temperature switch that turns on the fan to go bad. Also, a highly overlooked problem, make sure the fins on your radiator and condenser aren't blocked with debris. Shine a flashlight on the opposite side and look through. Good luck!

96 cutlass supreme 2 dr. coupe wont release from park also breake lights wont work

the brake light issue is probably causing the shifter not to work because when you press the brake it tells the shift lock system to allow the vehicle to be shifted from park. If there is no power there it won't work and both systems usually work off of the same switch. if you check the fuse panel for a stoplamp or brake fuse it will probably be blown....replace it and your shifter will probably work once again as well.
hope this works for you....good luck!
