No,not "into"red,but close to it. if it goes to red,you might have a failing thermostat. let me xplain. -a failing thermostat will either make your motor run too hot,or too cold,(the temp you see on your dash is for the motor)
NOW,you also have a temp sensor for the radiator fan,which is on the radiator.
SO,if the motor thermostat isnt opening,the rad' isnt getting the hot water(to cool off),in turn,the fan will come on later!!(hotter)
in conclusion,replace the engine thermostat,(it's cheap$$)

Where is the thermostat on my 2003 Saturn Ion Level 3? I have no steam or smell but my needle on the dash keeps creeping up to almost the red mark. When i drive and don't idle it goes back down. Hel


Sounds like your electric fan is not coming on. Do you have heat? if not it might be thermostat, if yes, listen for or look and see if your electric fan is coming on

Ford focus 2003 temperature gauge jumps to red


Check the operation of your thermostat.
Check that the radiator is filled with fluid and that there are no bubbles in the system (this should only be as a result of a radiator re-fill).
Check that the radiator fan comes on as the gauge needle moves over half way and into the red.

I have Rav4 1998 Temperature gauge needle goes all the way up to the red on 60 km and up and engine is not overheated the fan kicks in at 97C the needle comes down bit. I changed the Fan relay, temperature...


when the fan kicks in, how long does it stay on? if longer than 30 secs, have radiator cleaned or replace. During testing, turn off the airconditioner. Time the fan when it comes on and off. should be less than 1 minute.

My fans are not coming on when do they suppose to come on


The radiator fans should come on before the engine temperature reaches the 3/4 mark on the temperature gauge. If the needle goes anywhere near the red your fans are not working and you need firstly to look at the thermostat, and then the fan relay.

4.0 litre ford motor not using any water but overheating not using oil either


I believe you have electric cooling fans which are part of your cooling system . First , remove your radiator cap and allow the engine to warm up to operating temperature . The cooling gauge needle must be close to half way. You want to make sure the thermostat is open . Slowly raise the RPM to about 1500 while watching the coolant . You should see movement of the coolant indicating the thermostat is in fact opening . Once you verify that is OK , the Nextstep is to verify that your cooling fans turn on . Put the radiator cap back on and continue to hold the engine RPM at about 1500 . As the needle on the gauge moves to the center or a little bit higher , the cooling fans should start up . If the needle continues to climb towards the red zone but the fans don't come on , your problem will be in the cooling fan circuit . I suggest having a professional diagnosis be done .

yes, recommend you check to see if the fan is coming on. If not, check the relay for it. There are more troubleshooting steps we can try. Let us know what you find.
