What is the Location of thermostat - 1995 Buick Regal

you have thermostat for a/c and engine coolant, which one.

should be at the end of your top rad hose

The thermostat is locatud on the top of the engine towards the front underneath the upper radiator hose. You shouldnt have to drain all coolant to change the thermostat. There are usually only two bolts holding the thermostat housing to the engine.

follow the top hose from the radiator. it connects to the thermostat housing. a stuck thermostat will make the vehicule overheat but check anti-freeze level first

Follow the TOP hose on your radiator to where it connects on your engine block. The thermostat is under the metal piece mounted to the block which the hose is connected to. It typically has to bolts to remove and you will find the thermostat under it once you remove the mounting.

The thermostat is found at the end of the top radiator hose . Find the top radiator hose and follow it to the engine .There you will find a thermostat housing with the end of the hose attached . There will be 2 bolts holding down the housing to the engine. Undo the bolts and pull the housing off and the thermostat will be there.

The thermostat is located where the top radiator hose enters the block.
