Your vehicle has two thermostats,
a primary and a secondary
. The primary and secondary thermostats have different temperature profiles with respect to their opening temperature because they are located on different areas of the engine.
Where is the thermostat in a Dodge Journey?
Does Dodge Journey have 2 thermostats? The primary thermostat for the 2.0L diesel and 2.4L gas engines are located on the front of the water plenum in the thermostat housing/coolant inlet. The
2.4L engine has a secondary thermostat
. The secondary thermostat is located in the cylinder head under the water plenum.
Does a 2010 Dodge Journey have two thermostats?
There are
two separate thermostats
in your application, a primary and a secondary. The primary thermostat is located on the front of the water plenum in the thermostat housing/coolant inlet.
Why do some cars have two thermostats?
Their purpose is
more for aerodynamics than engine cooling
. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. Instead of manipulation of the air side of the radiator, the coolant flow to the radiator is varied.
What would cause a 2010 Dodge Journey to overheat?
While there are a variety of reasons your Dodge Journey is overheating, the most common 3 are a
coolant leak
(water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Can you run a diesel tractor without a thermostat?
You can run without a thermostat,
if you restrict the flow of coolant
. The closer the engine temp runs to 210, the more power it will produce, with less fuel consumption. The engine will also create less internal wear at this temperature.
What purpose does a thermostat serve in a car?
The thermostat is like a valve that
opens and closes as a function of its temperature
. The thermostat isolates the engine from the radiator until it has reached a certain minimum temperature. Without a thermostat, the engine would always lose heat to the radiator and take longer to warm up.
What does a thermostat do in a diesel engine?
The thermostat
controls the minimum normal temperature
. The thermostat is a temperature-controlled valve placed at the engine coolant outlet on most engines. An encapsulated wax-based plastic pellet heat sensor is located on the engine side of the thermostatic valve. As the engine warms, heat swells the heat sensor.
Where do you put water in a Dodge Journey?
You need to put the water
in the radiator
by removing the pressure cap once your vehicle cools down. You can also add the water to the coolant reservoir or recovery tank if your car is overheating to the point where there's steam.
How do you start a car after it overheats?
- Kill the A/C and crank the heat. Immediately turn off the air conditioner to reduce stress on the engine. …
- Find a safe place to pull over. Pull over and shut off the car. …
- Check and add coolant (if you have it). …
- Restart the engine.
Where is the thermostat in a 2012 Dodge Journey?
Does Dodge Journey have 2 thermostats? The primary thermostat for the 2.0L diesel and 2.4L gas engines are located on the front of the water plenum in the thermostat housing/coolant inlet. … The
secondary thermostat is located in the cylinder head under
the water plenum.
How do I know if my tractor thermostat is bad?
Look to see
if the coolant is swirling/flowing immediately
— that means the thermostat's stuck open. If the coolant doesn't flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it's hot, the thermostat's likely stuck closed.
Does a diesel engine need a thermostat?
Most, if not all, large diesel engines found in trucks and farm equipment employ a
dual thermostat system
. … Most engines have a radiator bypass circuit that allows coolant movement in the engine when the thermostat is closed (engine cold) to hasten warm-up and to eliminate localized hot spots.
Is it OK to remove thermostat?
TOM: Yes, Lee, removing the thermostat does make the car run cooler. But
you should never, ever do it
. … When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.
