It is easiest to remove the thermostat and drain the radiator by removing the lower hose. Dispose of the coolant properly. reinstall the lower hose and run water from the garden hose through the engine with it idleing until it runs clear. Then remove the lower hose to drain the radiator and reinstall the thermostat with the spring toward the engine. Then fill the radiator with coolant and start the engine up and top off the radiator after the thermostat opens. You should end up with about a 50/50 mixture of coolant and water. Good Luck Joe

If it has a coolant tank, that's the "cap".

The thermostat on a 1991 Buick Skylark is located near the engine. To find the thermostat, follow the top radiator hose directly to the thermostat.
