Overheating

252 Views 6 Replies 4 Participants Last post by  rsingl
My 2017 ats is over heating, I live in Hawaii and it only happens during the rain and traffic. I took a look at the fan while it was running hot and it wasn’t moving. Pushed it manually and it starting spinning though it didn’t seem like it was running at full speed if you ask me.

I have 50k miles on it. Getting it checked out next week but wondering if anyone else ran into similar issues and what was the resolution.

If pushing the fan gets it started (not a coincidence that it started when you pushed it), then I think it's the fan. Would make sense that it is overheating in traffic if the fan isn't running.

^^ Yeah that.^^
I just wonder what causes the fan to go bad like that, I’ve had other cars and never had a problem like that
Anything mechanical can break and the fan lives in a rough environment. It isn't unusual for an electric fan to need replacement, like everything else in the car the supplier cuts costs to the bone to make profit. Even mil/space rated components have a non-zero failure rate and it is much higher for consumer products given the cost constraints.

Prior to electric fans, I have had to replace three fan clutches on vehicles I owned in the 6 to 8 year old range.

As I recall, there are two different cooling fan wattage levels based upon the engine and optional equipment/package so make sure if you replace it yourself that it is the proper one for your model.

Right on, thank you for your time sir.

You are welcome! And although replacing broken parts is never fun, it sounds like you diagnosed the problem quickly which often isn't the case with overheating; it is often an intermittent condition that never occurs when it is easy to diagnose.
