After you've gotten 10 minutes of running or driving time on the motor touch your top radiator hose. It should be too hot to wrap your hand around. If its Luke warm the thermostat is bad. If the hose is blazing hot check the two hoses to and from the heater core if one is hot and the other is cold, suspect a heater control valve to be sticking or a blocked heater core. If you've had your radiator flushed and cleaned at least once since you've owned the car your system should be OK. I've lately seen many GM cooling systems with filthy colored Dex-cool antifreeze / water mix. In that case you'll need a complete acid cleaning done to your cooling system. It's best left to a dealer, radiator shop, or independent service shop do to the steps involved.

before you start the car today( this is important... the car should be COLD.. if you drive it the coolant will be HOT and if you remove the cap while it is hoy and under pressure you WILL GET BURNED with 3rd degree burns so wait for the car to cool off) .. check the coolant level.. if it is low you should .. depending on how long it has been since you flushed the coolant.. go have a coolant flush done... generally speaking that should be done every 2 years.. if your not doing to do that.. then buy the SAME color coolant... and put replace what is missing.. coolant breaks down over time and it lose its protection when that happens rust will build up in the radatior and that will start to slow the flow of coolant to the engine..
if you take the cap off the radatior and it is full.. or near full next I would think it is the thermostat.

All the answers given here are good ones for your problem and I would replace the thermostat first as its a cheap fix . I own a 1991 Caprice also and do all my own repair. another thing that happens to a caprice is the fins inside the water pump degrade so they don't push enough water through the system the car wont overheat (THIS HAPPENED TO ME). But yes, replace the thermostat

I agree with all of the above answers. One other thing that wasn't mentioned was the heater control valve, that starts and stops the flow of hot coolant to the heater core.

It is one of two things. Either your thermostat is sticking, or your heater core is needing flushed. It could be one other thing, the control that you use to regulate the temperature coming out of the heater. But usually it is one of the first two.

thermostat, on a big car like that shouldn't be hard to find. they are like 6 bucks at any place like napa or something, follow the radiator hose to the engine should be a little housing compartment, its in there.

Either you are low on coolant or you need to replace your thermostat.
