458 engine water temps? mine gets near 250F / red sometimes...

Anyone know if its normal for it to get up there? It has been relatively hot here in LA recently, and when it happens it is when I am driving it relatively hard on the street and at times come to a slow down due to traffic.

I am worried that it doesn't seem to evacuate heat fast enough or well enough... temperature gets near the red on the digital water temp gauge inside the car.

So obviously when I slow down its not getting enough air flow, but I would think the car should be equipped to deal with that...

Insight? Ways to upgrade the cooling?
What tire temps are you guys seeing also? I am getting front tire temps of around 170F-180F when driving hard, but these also seem to take a bit to dissipate.

I would get it checked as 120C is not normal. Are the radiator fans working fine? They should start at avg 80C/175F.

Rik- I believe the 458 has all silicone hoses, so they should not be a problem, and I doubt Dave is making kits for the 458 yet.

The car should still be under warranty unless it is a very early car, and I would take it to the dealer and have him check it out and make sure the fans, thermostat, etc are working as designed, and have him bleed the system after a flush and change of coolant. The 458 water temperature gauge in the TFT is redlined at 245 F, but I am not sure when the high water temperature warning lamp illuminates.

F- The water temperature warning indication has not been on, has it? Also, normal internal tire temperature has been published in some TPMS sources as -40 F to 246 F and you are well below that.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Rik- It was a really good treatise on how to fix overheating problems on a 456. You should save it as a Word document for next time. I have been known to do that with stuff other people write. Then I sound smarter than I am based on somebody else's work.

The Times New Roman 2 does lead me to a lot of typos, but do not think Andrew knows how to fix it because I have asked in the past. All TNR is good for is saving ink, which makes it kind of useless on the internet.

After a hard run I see 110c to 120c when slowing down, but after ten mins is soon cools.
How long does it take to cool down?

Paul- It should be only a few minutes. If you read the owners manual, it says to let the engine idle for a couple of minutes after you have really ridden her hard. This circulates the water and air and prevents heat from localizing with no coolant or air flow.

Yes i would guess so mine takes that long to start to lower.
I don't really consider it as it seems normal to me, after a hard drive.
