Where is the thermostat on a 2006 Chrysler Sebring convertible 2.7 liter?

The thermostat on a 2006 Chrysler Sebring Convertible 2.7L is located on the engine, typically near the front and somewhat lower down. It's not easily accessible; you'll need to remove various components (possibly including some hoses and possibly the water pump) to get to it.

It's strongly advised that you consult a repair manual specific to your vehicle's year and engine. These manuals will provide detailed diagrams and instructions to locate and replace the thermostat safely and effectively. Improperly accessing or replacing the thermostat can lead to damage to the engine cooling system.

Trying to find it without a repair manual will be difficult and potentially frustrating. The best approach is to acquire a manual (available online or at auto parts stores) before attempting any work on your vehicle's cooling system.
