Where is the thermostat located on a Chevy ck 1500 6 cylinder 1500?

On a Chevy CK 1500 with a 6-cylinder engine, the thermostat is typically located on the engine block, near the top of the engine, under the housing connected to the upper radiator hose. To access it, you'll generally need to remove the thermostat housing, which is secured by bolts. Make sure to drain the coolant before attempting to replace the thermostat to avoid spills.
