The thermostat is inside the thermostat housing on the engine, at the front where the upper radiator hose attaches. On the 2011 Chrysler 200, the exact housing location depends on the engine you have (2.4L I4 or 3.6L V6), but both are mounted on the front of the engine and accessible from the engine bay top.
Engine options and the thermostat housing
Because the 2011 Chrysler 200 could be equipped with two engines, the thermostat sits in a housing on the engine for both, with the mounting point differing slightly by engine design. Here is where to look for each engine.
- 2.4L World Gas Engine: The thermostat sits inside the thermostat housing on the front side of the engine block, where the upper radiator hose connects to the water outlet.
- 3.6L Pentastar V6: The thermostat is inside the thermostat housing mounted to the front of the engine, also connected to the upper radiator hose at the water outlet.
In short, the thermostat is always inside the housing at the front of the engine where the upper radiator hose meets the engine, with the exact appearance or orientation varying by engine type.
How to replace or locate safely
Before you start, ensure the engine is cool and you have the proper tools. The following steps outline a typical replacement approach; refer to the factory service manual for torque specs and engine-specific details.
- Disconnect the negative battery cable to prevent electrical shorts.
- Place a drain pan under the radiator and drain coolant as needed to relieve system pressure.
- Locate the thermostat housing at the front of the engine; loosen the hose clamp on the upper radiator hose and detach the hose.
- Unbolt the thermostat housing from the engine and remove the housing to reveal the thermostat.
- Remove the old thermostat and gasket/O-ring. Clean the mating surfaces thoroughly to ensure a proper seal.
- Install the new thermostat in the correct orientation (often with the spring-side facing into the engine) and reinstall the gasket or O-ring.
- Reinstall the housing with bolts to the specified torque and reconnect the upper radiator hose.
- Refill coolant and bleed any air from the cooling system according to the owner's manual or service manual.
- Start the engine, check for leaks, and monitor the temperature gauge to ensure the cooling system is functioning properly.
Replacing the thermostat is a straightforward job for many DIY enthusiasts, but if you are unsure or lack the proper tools, consider professional help to avoid coolant leaks or engine damage.
Summary
The 2011 Chrysler 200âs thermostat sits inside the thermostat housing on the front of the engine where the upper radiator hose connects. The exact location varies by engine: 2.4L I4 engines have the housing on the front side of the engine block, while 3.6L V6 engines also use a front-mounted housing. Replacement involves draining coolant, removing the housing, swapping in a new thermostat and gasket, and refilling/bleeding the system. Always consult the service manual for engine-specific torque specs and orientation.
