Where is the thermostat on a 4 cylinder 2000 dodge Dakota?

The 2000 Dodge Dakota doesn't have a thermostat in the traditional sense that you'd adjust. The thermostat is a crucial part of the engine's cooling system, but it's a mechanical component located inside the engine, usually at the top of the engine block or in the intake manifold. You can't adjust it like a room thermostat. To access it, you'll need to remove some components, which requires mechanical knowledge and tools.
