Where is the thermostat located on my car? I cannot find it and I need to replace it

Hello, there are three different V6 engines. 3.4L VIN E, 3.8L SC VIN 1, and 3.8L VIN K. It looks like the 3.8's are the same area. The first two pics are the 3.4 and the last two is the 3.8. Please ensure you provide all the engine information for the car to ensure you are provided the correct info. Thanks.....have a great day.

From the diagram in a previous answer it looks as though the Impala's thermostat is located inside of where the radiator hose slips onto part of the manifold that comes from the engine block. If this is correct how do I remove and replace the thermostat?
Thank you in advance,

yes, as the diagram below shows, there are two bolts needing to be removed from the thermostat housing.

Thank you for all your help. I bought the thermostat and am going to replace it tomorrow. One more question. Is there supposed to be a gasket the goes between the manifold and the engine block or just the rubber round one that is already on the thermostat?

Years ago I replaced one on my 1993 Chevrolet Lumina and I think I remember that car had a gasket that went on the manifold. Just want to make sure I have anything.
Thank you again for all your help.

The thermostat gasket is the kind of thick round gasket on this vehicle, that is it.

where is the thermostat on my 2000 impala and how do i replace it or at least can i see a diagram? thank you

On a 3.4 the thermostat is on the far right side while standing in front of the vehicle, below the intake. You will need to remove the exhaust crossover and some coolant tubing from the top of the engine to get to it.

3.8L
Drain about 1 gallon of coolant from radiator
Locate removable housing a the engine end of the upper radiator hose and remove
Note how thermostat is installed in housing
Clean both surfaces
Install new 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

2. Install radiator cap. Close air bleed screw. Fill coolant reservoir with 1 quart (.95L) of coolant.

NOTE:
The Low Coolant warning/indicator lamp may come on after this procedure. If after operating the vehicle so that the engine heats up and cools down three times, the Low Coolant warning/indicator lamp does not go out, or fails to come on at the ignition check, and the coolant is above the full cold mark in the reservoir, refer to Low Coolant Warning/Indicator Lamp in Electrical Diagnosis. If at any time the Temperature warning/indicator lamp comes on, immediate action is required. Turn OFF the engine and allow the vehicle to cool. Do not remove the coolant recovery reservoir cap at this time.

Can I get past the muffler exaust n heat shield to get the thermostat to come off ? And do I have to take the half inch pipe off where the two little hoses and the bracket attach just above the thermostat on a 2001 Chevy venture van
