You don't have to, but without draining the radiator, you will have coolant all over the engine when you replace the thermostat. This is a good time to install a fresh 50/50 mix of antifreeze & distilled water. Don't forget to bleed all air from system.
below the raditor hose that's connected to the thermostat.
Low coolant, bad thermostat, clogged radiator, bad waterpump, bad headgasket, etc
replace the coolant sensor, the one next to the thermostat housing.
it could be a bad thermostat or lack of water/coolant in the engine itself. Coolant will boil itself away if it was not mixed right. If the thermostat is sticking or not working, it wont let coolant that is in the block move past the radiator to cool, allowing the temperature of the block to increase and over heat Thermostat not opening?
where do i put coolant in for 1994 Chevy s10 pickup

Located at the engine end of the upper radiator hose. Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-fill coolant slowly to prevent an air lock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
Should be located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Install new thermostat and gasket Re-fill coolant slowly to prevent an airlock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
assuming it is a 5.0 L it is located on front side of motor just left of thermostat housing however it can also be found in the back of engine located in the supply line to heater core more than likely beside thermostat

There is a spring in the thermostat, And the spring goes down into the intake.
