What does engine over temp mean?
This temperature warning light means that your engine is running at a temperature that is too high – in other words, your engine is overheating. If your vehicle’s cooling system is working properly, this should never occur.
What is the normal operating temp for a 2004 Cherokee 4.7?
What is the normal operating temperature be for a 2004 Cherokee 4.7. Would that also about 210 ? This weekend I will be replacing the Thermostat, thermostat sensor, radiator cap and doing a radiator flush. hopefully this will resolve the over heating issue. I have been noticing my clutch fan as been coming on more often.
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.
What causes an engine coolant temperature sensor to erode?
Finally, no change in the return signal, would indicate a faulty (ECT) sensor. Even general wear and tear can cause the (ECT) sensor to erode over time. So, the engine coolant temperature (ECT) sensor is designed to be; fully submerged in coolant.
What should normal operating temp of jeepz be?
This is an old post. FYI you need to run a 195 deg thermo. The temp will run at 210 and the PCM will adjust the air fuel to try to attain 210. By running 165 you are not allowing the engine to come to temp and gain the efficiency it can reach. I doubt the intake and headers directly caused you to run hotter.

Why is my car’s coolant not reaching operating temperature?
A cold car’s coolant temperature matches the outside temperature, so I assume the sensor is doing good. First thought would be a faulty thermostat – coolant is always allowed to go through the radiator and does not let the engine reach proper temperature. So I changed it to a new one. And you know what that did? Nothing, same problem.
What happens when engine heats up to operating temp?
As the engine heats up the ring-cylinder mate becomes looser so that the engine will run smoother and easier…but if there is too much wear the combustion gases will begin to blow by the ring-cylinder surfaces and will cause each stroke to lose power.
