Hi everyone, I have been experiencing this issue with my car lately, I've been turbo for about 3k miles and the weather started to get hot from the 90 to 95 degrees, I noticed that now the coolant temp is around 199 to 210 on highway, with the AC on. Before when it was around 70-80 degrees the temp stayed mostly around 185.

Even with the ac off, I noticed that it still climb to 205, even at night when its cooler, could this be the sign of a blown head gasket? or are these temps normal for a turbo car?

Also does everyone daily drive there turbo s in the summer without any issues?

I am talking about 100 to 115 degrees , at least that's the summer I get where i live

Someone correct me if I'm wrong, but I'm pretty sure those temps are fairly normal and you have nothing to worry about.

Yep, I daily drive my turbo car during the summer and its fine.

195-210 I thought was normal?

Those are normal operating temps. Nothing to worry about.

It might be fine at 210+ but if your going to worry about it, I would get a new radiator. Better safe than sorry and you can't go to big on a radiator, hell the thermostat will keep the temp where its supposed to be.

From what I've read, you don't need to worry until 220+. I don't think you need to upgrade the radiator unless you plan to track or autocross it. Stock should be fine for most strictly street applications. Your money though...

I had the same cruising temps when turbo, problem is if you get stuck in traffic and it starts to climb over 215-220.. my serial gauge would always start flashing H2O but not show the actual temp... so I ended up running my heat a lot in the summer to help, it sucked lol

Thanks for all of your responses, i guess the AEM serial gauge cause me a little bit of panic when i saw the coolant temp in those ranges, which is not what i was use too

Do you run the default ahem ect values?

Im turboed and live in cali, outside temperatures can reach 110 degrees and the temperature is normal. I do not think you should be worried.
