When first started you should hear a slight roar that will quickly fade to quiet. This roar is the fan clutch engaging the fan and the sound of the fan pulling air. Then when the engine gets to above normal operating temperature, you should hear it start to roar again until the temperature lowers. This is the clutch operating normally.

What causes a Dodge Ram truck to overheat?

If any of these components are faulty or deteriorated, the system can have “air trapped” within it that prohibits coolant flow, which can cause the motor to not cool properly. When this happens, the thermostat doesn’t get the reading to inform the on-board ECU that everything is alright and will flash the indicator that the vehicle is overheating.

What should coolant temp be when engine is hot?

With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.

They send a signal to the gauges so you can monitor engine temperature, they tell the radiator fans when to kick on or off, and they let the ECU know how warm the engine is so that it can fine-tune the fuel delivery to give you maximum performance as well as fuel efficiency.

What’s the normal oil temp for a Dodge Ram 1500?

My last Ram was a 2014 1500 with the V6. That one ran with the tranny at 190-195 Coolant in low 200’s, but oil normally at or below tranny temp. Of course those numbers all skyrocketed if I was towing anything. I definitely like the tranny temp on the V8, but wondered if it’s normal for the oil to run hotter than the coolant with this engine.

When did the coolant change on Dodge Ram?

If left unchecked, cooling problems can lead to series engine damage like warped heads. From 1994 to 1997, the Ram had two coolant temp sensors (CTS) to handle the different functions. In ’97, they began switching over to one multi-function CTS, and in ’98 and up they all had just one.

Where are the sensors on a Dodge Ram?

On trucks with two sensors, the one on the left of the thermostat housing is the sending unit for the gauge, and the one behind and to the right sends signal to the ECU. Depending on the problem you are having, you will likely just change one or the other. Figure 1.

Why does my Dodge Ram 1500 have no heat?

Either your heater core is blocked and isn’t flowing coolant anymore, or your blend door is also messed up. The blend door itself is not driven by vacuum lines – this one is driven by an electronic servo motor. The servo coupler is a cheap plastic piece of shit that gets broken over time. This is the weakest link in the blend door system.

Where is the HVAC switch on a Dodge Ram 1500?

If you have vacuum at that line inside the engine bay, then check the HVAC switch at the dash. That black vacuum line you checked inside the engine bay leads to the back side of this thing: Pop your dash bezel off and take a good look at the backside of this thing. It is not an electronic switch – it is a simple vacuum port switch.

How does the HVAC work on a Dodge Ram?

The HVAC box is basically spring loaded to default to defrost mode. The air setting dial on your dashboard redirects vacuum to a series of diaphragms around the HVAC box to change where airflow goes.
