No. The Dodge Journey uses a single thermostat in its cooling system.
According to service manuals and reputable automotive references, the Journey's cooling circuit uses one thermostat located in the engine's thermostat housing to regulate coolant flow to the radiator. The heater core is controlled by the climate system, not a separate thermostat. This layout applies across the model years and engine options commonly found in the Journey, though exact component layout may vary slightly between engines.
Thermostat design in the Journey
The following points describe what to expect in the Dodge Journey's cooling system and how to verify this configuration in your specific model year.
- The cooling system is designed around a single thermostat housed in the engine, typically at the front of the engine near the water outlet or thermostat housing.
- There is no second, independent thermostat for a separate cooling loop or the heater core in the Journey’s standard configuration.
- The heater core circuit operates via the climate control system and does not rely on a second thermostat for temperature regulation.
- If the thermostat fails, you’ll usually see symptoms related to a single-thermostat design, such as overheating when stuck closed or running cooler than normal if stuck open.
In practice, the Journey’s cooling layout centers on one thermostat. For model-year specifics and exact part placement, consult the vehicle’s service manual or a Chrysler-Dodge dealership.
Additional context and verification
If you’re diagnosing cooling issues or planning thermostat replacement, follow these steps to verify the layout on your vehicle:
- Identify the thermostat housing location on your engine and confirm it aligns with a single-thermostat design described in the manual.
- Check for a secondary thermostat or separate heater-core valve in the cooling circuit—most Journey models do not use one.
- Inspect symptoms and coolant flow to determine whether the thermostat is operating correctly (opening/closing at the proper temperature).
By following the manufacturer’s guidance and using the correct replacement parts, you can ensure the cooling system remains reliable without introducing a dual-thermostat configuration.
