Where is the thermostat on a Dodge Ram van 3500?

The thermostat on a Dodge Ram 3500 van (like most vehicles) isn't something you'll find easily accessible in the passenger compartment. It's located within the engine cooling system, usually somewhere on the engine block itself or in the housing connected to the engine. To access it, you'll need to:

* Consult your vehicle's repair manual: This is the best source for the exact location and details on replacing it. The manual will provide diagrams and instructions specific to your van's year and engine.

* Use a repair manual app/website: Several apps and websites (like Chilton's or Haynes) provide repair manuals for various vehicles. You'll need to input your vehicle's information to access the relevant information.

Without knowing the year of your Dodge Ram 3500 van and the specific engine type, it's impossible to give you a precise location. Accessing the thermostat usually involves draining some coolant, removing some hoses and possibly other components, making it a job best done with the proper tools and knowledge. If you're not comfortable doing this yourself, it's highly recommended to take it to a qualified mechanic.
