Where is the thermostat on a 1999 dodge caravan?

The thermostat on a 1999 Dodge Caravan is located under the intake manifold. This is a fairly involved job to replace and requires mechanical skills and the right tools. It's not easily accessible like some thermostats. You'll likely need to consult a repair manual specific to your 1999 Dodge Caravan's engine (e.g., 3.0L, 3.3L, 3.8L) for detailed instructions and diagrams.
