What is Normal Engine Coolant Temperature?

engine coolant temperature

Normal engine coolant temperature depends on a lot of factors.  Before we get into what normal engine coolant temperatures are, a better question you maybe should ask is what temperature is your engine really running at?

Does your car have a temperature gauge?  Can you really trust it? Many cars being sold today simply have a blue thermometer dash light that turns off once your car is warmed up and a red thermometer dash light that turns on if your car gets too hot.  Even your owner’s manual probably doesn’t tell you what temperature those lights turn on and off at.

One vehicle we test drove did have a temperature gauge closer inspection the gauge stayed centered even though the vehicle’s actual coolant temperature ranged from 140 degrees up to 230 degrees!

So how can you be sure of your engine coolant temperature?

  • If your car was built before 1996, install a mechanical coolant temperature gauge made by a reputable company
  • If your car is older than 1996 it will have an OBDII port.  Get a device to plug into that port to read the coolant temperature.  One of our favorites is made by Foseal and can be linked with an app on your phone like Torque which will allow you to see the value of various sensors in your car’s engine.

Now that you know what your car’s engine coolant temperature actually is, watch it for a few days in a variety of driving situations.  If you have an OBDII scanner, you may even be able to graph coolant temperatures in your app and track them that way.

The best place to start in comparing your vehicle’s normal engine coolant temperature to see if it’s correct is with your thermostat setting.  If you call your local auto parts store, like one of our partners below, they will be able to tell you what temperature your engine’s thermostat is designed to start opening.  This will likely be somewhere in the 160 to 190 degree range based on what your drive.

Another thing to consider when watching your engine coolant temperature is what the engine cooling fans are set to.  If you are driving slowly or stopped idling the fans keep enough air moving through your radiator to keep your engine cool.  Engine cooling fans may engage at one speed or multiple speeds and may kick on anywhere between 180 and 220 degrees. Ensuring your engine cooling fans are working properly is important to keep your car cool but usually doesn’t tell you much about your engine’s normal operating temperature so consider keeping your vehicle driving over 35 MPH when determining what temperature your vehicle operates at.

If it seems like your vehicle is running too warm, make sure your cooling system is working at peak efficiency by performing regular coolant flushes, checking for leaks and making sure your radiator isn’t damaged or clogged with debris.

If you’re sure your cooling system is working correctly, try adding BlueDevil Engine Cool to reduce your engine temperature up to 25 degrees!

    Hi there.
    Thanks very much for the valuable information.
    I have chevy Malibu 2018, when driving in high speeds (130km+) the coolant temperature is 107°C then goes down.
    In normal speeds it is around 97°C.
    I wonder if the 107 is normal for the car.

    I have everything else normal and the car has no other problem, the check engine light is off.

    Best Regards


    • BlueDevil Pro on June 4, 2020 at 10:34 am


      Thank you for asking about your Chevy Malibu. It seems that the normal operating temperature range for your vehicle is between 190-225 degrees Fahrenheit, so the temperature you read still falls within the normal range.

      Thank you!

    What is the normal temperature for Pontiac Solstice GXP 2007?

    • BlueDevil Pro on July 6, 2020 at 8:50 am


      Thank you for asking about your Pontiac Solstice. While we don’t have your vehicle specific information, normal operating temperature for most vehicles can range between 190-220 degrees Fahrenheit.

      Thank you!


  3. Giuseppe on July 17, 2020 at 9:49 pm

    What would be the ideal temperature range for a mildly modified 350 small block Chevy? Right now the engine runs between 190 and 210 degrees with Derale 4000 cfm electric mini fans. Is 210 degrees too high? Thank you.

    • BlueDevil Pro on July 20, 2020 at 8:26 am


      For most vehicles, the normal operating temperature will range from about 195-220 degrees Fahrenheit. It does not sounds like 210 degrees is too high.

      Thank you!

    My Ford Escape 1.6T idles around 210F, is that normal?

    • BlueDevil Pro on September 15, 2020 at 8:25 am


      It appears the normal operating temperature for your Ford Escape ranges from 180-210 degrees Fahrenheit. Although on the higher end, it does sound like it is still in the normal operating temperature range.

      Thank you!

    Is it normal that the indicator gauge fluctuates a little bit while driving in Rav4 ?

    • BlueDevil Pro on October 5, 2020 at 8:42 am


      If the temperature gauge keeps fluctuating, it could be the sign of a faulty thermostat. This is very inexpensive and the easiest component to replace, so it would be a good place to start.

      Thank you!


  6. Javier on November 5, 2020 at 11:07 pm

    I have a Chevy Malibu 2011 lt. And the my gauge stays at C does not even out . Do I have a leak ? Or faulty radiator ?

    • BlueDevil Pro on November 6, 2020 at 8:35 am


      Thank you for asking about your Chevy Malibu. Based on your description, you may have a faulty thermostat and/or faulty temp sensor. The thermostat is the least expensive and easiest to replace, so it would be a good idea to start there. If the problem persists, you may want to look into a temperature sensor replacement.

      Thank you!

    Hello! I have a 2019 Jeep Compass latitude. My coolant temperature gage reads 223F usually. Is this a normal temp? I guess a better question should be what temperature should I be concerned about? My dealer said it could go up to 230 but this just seems high to me?

    • BlueDevil Pro on December 2, 2020 at 10:20 am


      Thank you for asking about your Jeep Compass. There are vehicles that will have normal temperature ranges that are higher when compared to other vehicles. It would not be out of the ordinary if 223 degrees Fahrenheit was within normal operating temperatures for your Jeep, especially with it being a newer vehicle.

      Thank you!

    I Have A 2012 Chevy Cruze 1.4 Lt with Turbo With 144,000 Miles & My Coolant Temp Goes To 233 Sometimes , Is That normal ?

    • BlueDevil Pro on January 22, 2021 at 8:22 am


      Thank you for asking about your Chevy Cruze. The temperature you mentioned seems a little high for your vehicle. Does it quickly go back down and kind of hover around that temperature? Have you noticed any other issues with the vehicle? It may be best to bring the vehicle to a certified ASE mechanic for a proper diagnosis.

      Thank you!

    Hello. I have a 2016 lexus is350 f sport. My temp runs between 212 and 219. Is that normal?

    • BlueDevil Pro on June 8, 2021 at 8:45 am


      Thank you for asking about your Lexus. Although it may seem high, normal operating temperature range for most vehicles falls between 195-220 degrees Fahrenheit. If no warning indicators or check engine lights are coming on, and the vehicle seems to be driving normally, you should be fine.

      Thank you!


  11. Mr. RF on June 20, 2021 at 6:34 am

    hi my toyota yaris 2016 has 81-86degC running temp during winter time while it increases to 88-96degC during peak of summer here in Saudi Arabia.

    Coolant level is normal and rad cooling fan works well both low speed and high speed depending on condition.

    Is this normal for a wide range of operating temp for this type of small car?

    • BlueDevil Pro on June 21, 2021 at 8:30 am

      Mr. RF-

      Thank you for asking about your Toyota Yaris. Yes, the temperature ranges you have mentioned would seem to fall within normal operating temperatures for this vehicle.

      Thank you!


  12. Cesar B on July 31, 2021 at 8:46 pm

    I own a Hyundai elantra 2018 SEL version (engine 2.0 L 4-cylinder) and recently bought a bluetooth OBD2 tool (Bluedriver)
    While checking the coolant temperature it reads that the max temperature is 221f (105c)
    I am just wondering if that is okay for that type of car.
    I just want to make sure if the engine temp is within the normal limits

    Thank you in advance.

    • BlueDevil Pro on August 2, 2021 at 9:10 am


      Thank you for asking about your Hyundai Elantra. The temperature you mentioned does seem a bit high, however, it may still fall within normal operating temperature range for your vehicle. Because it should still be under warranty, it may be worth bringing the vehicle to the dealership to discuss.

      Thank you!


  13. Tina on October 11, 2021 at 4:03 am

    HI there I have a 2012 Dodge Charge 3.6V and it seems to me that it is running high… around 200 degrees F. It also seems to lack the power to really go very fast anymore…. Is this normal temp rang?

    • BlueDevil Pro on October 11, 2021 at 8:49 am


      Thank you for asking about your Dodge Charger. 200 degrees Fahrenheit would fall within the normal operating temperature range for your vehicle. If you feel the engine is lacking power, it may be best to bring the vehicle to a certified ASE mechanic for a proper diagnosis. Depending on the mileage on the vehicle, it may be due for a service.

      Thank you!

    My lower radiator hose never gets warm. I just replaced the radiator and 180 degree OEM Nissan thermostat in my 2008 Nissan Frontier. I filled the radiator using a burping funnel while the engine was cold and then turned the engine on and burped some more while squeezing the upper radiator hose until there were no more air bubbles. I put on the radiator and reservoir caps and watched the temperature reading using a check engine tester. The temperature settled out at a temperature between about 188 and 198 even as I drove the car around the neighborhood about 25 to 30 mph. The heat was working fine in the cab and both heater hoses were hot. The upper radiator hose was too hot to touch but the lower radiator hose was about 70 degrees (ambient air temperature).

    Is this normal? Shouldn’t the lower radiator hose get warm/hot?

    • BlueDevil Pro on October 18, 2021 at 8:35 am


      Thank you for asking about your Nissan Frontier. The lower radiator hose should always be cooler than the upper radiator hose, as the upper hose transports the hot coolant from the engine into the radiator to be cooled back down and the lower hose is transporting the cooled coolant from the radiator radiator back into the engine.

      Hope this helps!

    Hi, I have a 2004 citroen C3 diesel,
    Usually, on a normal ambient day (around 8+ degrees c), It usually hits around 3 temperature lights (halfway) by the time I get to work (around 15 minutes). Today was slightly colder (2 degrees c maximum), and I noticed that it had only reached 2 lights when I parked up, after a bit of waiting it did hit three lights. Is this normal? Do colder climates mean that engines take longer to heat up fully?

    • BlueDevil Pro on January 4, 2022 at 9:42 am


      Yes, it is not uncommon for the engine to take a little longer to warm up when the climate is colder. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

    Hi, I have Toyota Vios/Yaris 2008 manual and the coolant temperature is always somewhere 89 to 96 degree celcius. But when going way uphill it goes up to 110 degree Celsius . Is it normal? Thanks

    • BlueDevil Pro on January 4, 2022 at 10:44 am


      Thank you for asking about your Toyota. 110 degrees Celsius, or 230 degrees Fahrenheit does seem higher than normal operating temperature. Are you noticing any issues with engine performance when going up a hill? Depending on use and mileage, it may be due for a service. Having the cooling system flush and refilled would be a great place to start, as this would ensure it wasn’t a clog/restriction causing the temp to start rising. Having the thermostat looked at and possible replaced would also be a great place to start.

      Thank you!


      • RONSKI C RE JESUS on January 4, 2022 at 7:31 pm

        I already replaced the coolant and the thermostat and now planning to replace the radiator. What is the acceptable coolant temperature when going uphill?

        Thank you BDP

        • BlueDevil Pro on January 5, 2022 at 8:19 am


          Normal operating temperature typically ranges between 195-220 degrees Fahrenheit.

          Thank you!
