What should the temp be on a Jeep Wrangler?
Then depending on what you do with your jeep it is “ok” to see temps up to 240. At that temp you need to change what you are doing otherwise you will force the engine to defend itself. Either by de-fueing or going into limp mode etc.
What’s the operating temp of a 1988 Jeep Cherokee?
1988 Jeep Cherokee w/ 410,000+ miles. Now a 100% Electric Vehicle! Hi, I was going to post a similar thread. My 91 YJ (with a 4 banger) had an operating temp of 210°F. I just replaced the thermostat (and heater core and their hoses along with a rad flush) with a 180°F variety.
How does the cooling system work on a Jeep Wrangler?
A cooling system is comprised of six main parts: Your coolant is designed to absorb heat from the engine block. Coolant is pushed through the engine block via the water pump and then through a series of fins and tubes inside the radiator that allow the heat to dissipate.
How does the coolant sensor work on a jeep wranger?
Coolant temperature sensor test and change for the Jeep Wranger. Coolant Temperature Sensor monitors the temperature of the water in the engine. The PCM uses this temperature reading to adjust the fuel injection and timing. In some cases the PCM uses the reading from the sensor to turn on the electric cooling fan if so equipped.

What should my operating temp be on my 91 YJ?
My 91 YJ (with a 4 banger) had an operating temp of 210°F. I just replaced the thermostat (and heater core and their hoses along with a rad flush) with a 180°F variety. Now my operating temp has dropped to about 185°. I assume this is because of the thermostat change (and possibly the other cooling system replacements).
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.
Where is the temp sensor on a Jeep Cherokee?
Second, the temp sensor for the gauge is at the back of the engine in the head, the hottest place in the engine cooling system. It might be 220° there, but only 195 at the stat. It is a problem with a long engine block with the coolant coming all the way from the front.
How many horsepower does a Jeep Wrangler TJ have?
On average 4.0L Wrangler TJ engines registered 190 horsepower. While the DOHC 2.4L engine may have been cheaper, it couldn’t handle aftermarket upgrades to your suspension system or tires like a 4.0L could. Jeep also introduced the NSG 370 six-speed transmission in 2005. While faster, it had less torque than its predecessors.

What should the temp be on a jeep EVIC?
When temperatures reach above 60° C (140° F), or if the sensor is shorted 60° C (130/140° F) will appear in the display in place of the actual temperature. When temps fall below – 40° C (- 40° F) or if the sensor has an open circuit, – – ° C (- – ° F) will be displayed on the EVIC.
What’s the coolant temp on a jeep 5.7L?
On the 5.7L, the fan turns on full at ~224°F, its thermostat temp is 203°F, with good airflow through the radiator, like moving at some speed, it typically runs a few degrees cooler than the thermostat 203°F and very hot days or with heavy loads, it might run a degree or two higher than 203°F.
Why is the outside temp on my Jeep stuck?
Depending on you situation this may be the cause. The system will display the last known temperature when starting the vehicle and may take around 5 minutes at a continuous speed above 40 mph (64.3 kph). Short trips may not give the system enough time to update before you switch off the car.
Where is the temp sensor on a jeep?
The one wire sensor in the back sends temp readings to the gauge in the Jeeps dash. If you temp gauge isn’t acting right, replace the one wire. The two wire sensor located in the thermostat housing sends its signal to the PCM. For poor performance issues and testing we are going to look at the two wire up front.

Why is my Jeep Wrangler coolant not working?
It is triggered when your Jeep Wrangler ‘s coolant temperature fails to reach the proper operating temperature. It’s a generic powertrain code, which means that regardless of who manufactured the vehicle, it’ll have the same meaning (1996+).
What should the temp of the coolant be?
The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). Boil-over won’t occur until about 265F degrees, because of the pressurization (15 or 16 psi).

Wear and tear from age. Old coolant that has become corrosive. Leaking around where it screws in or where the electrical connections. Cracks in the plastic where the harness connects on to it. It’s really not a sensor that fails often. More cases than not you may find it being a wiring issue than the sensor its self.
How to change the temp of the coolant sensor?
Also a way to vary the temperature of the sensor. Something like a pan of water on the stove top over low heat. Use a thermometer to measure the water temp as it climbs. Not the water temp as you measure the resistance and compare it to the chart below. See YouTube video at the bottom of the page.
