Temp Spikes at idle

[ModRacerDSM]

When I'm driving my car the fuel temp is normal but when I put it in neutral and let the car idle the temp spikes. Any ideas as to why this is happening? today, just sitting in a lot, the temp went over 2000.

What modifications are done to your car?

Are you talking about coolant temperature?

huh fuel temp 2000 degrees

I'm guessing you are talking about coolant temp and meant to type 200. 200 degrees is okay

Check to make sure fans (radiator) are working. Possible that the coolant temp sensor might be defective.

this is what i get for telling my friend to post this and not doing it myself. Lets try again. my engine temp gauge, not fuel temp i have no idea why he said that? spikes when I idle. i can let it sit and it will go over 200 degrees, not 2000 haha. Usually when im running it it hardly goes above 160. I doubt that theres anything wrong with the sensor. So any ideas on to why my engine temp is spiking while idling? And dont worry hes getting a good smack for being an idiot.

Its simple.... no air flow over the radiator at idle. It will happen on any car, turbo or non-turbo

As long as your cooling system is in good working order, 200* is nothing to get excited about.

yeah fans are spinnin fine. Is there a way to fix the no air flow problem?

 

[BogusSVO]

Drive the car!

If the fans cycle on and off like they should all is fine.

A cold block, a temp under op temp, will have more wear than an op temp block.

I think our themostat opens at 190 degrees? 200 degrees is nothing to worry about.

Ok now I understand hahaha! If you run your defrost or heater with your a/c button fully pressed the a/c fan will always stay kicked on. it lowers the temp at idle a bit. really your are all good though man. I have to do that in my Talon during the summer because of hot start issues
