So let’s make this short and sweet. I’m a delivery driver and don’t know a ton about cars, so I need my car to make money to fix my car.

about a week or so ago, my check engine light came on, so I got it checked at autozone and they said it’s my thermostat. I haven’t been able to replace it because I don’t have a jack but that’ll be done over the coming weekend.

fast forward to yesterday. my car makes an obnoxious whistle at seemingly random times, as well as the temp gage saying it’s overheating when I idle(that overheating has been doing it since the CEL came on) and i just kinda attributed it to the Thermostat. Also my heat doesn’t work while I’m idle.

then today, the whistle has gotten worse, and more frequent. I noticed while coming out from a delivery a little bit of smoke coming from my engine bay, hmm, weird but it’s cold outside so maybe that’s it. I popped the hood to check to see what’s going on, and nothing looks to be wrong except when I put my hand over the engine it was blowing air out at me, and I feel like that’s not normal.

a couple things I thought were the whistle being my vacuum tubing, and the temperature related things being my thermostat. But then with the smoke and the air blowing from my engine I got kinda concerned. Any help is greatly appreciated.

i attached a video of the whistle noise coming from my car.

Even if the car isn’t smoking other than that one time, and it’s still running and driving perfectly fine?

The reason I’m asking is because I blew the head gasket in my oldsmobile before getting my civic, and it smoked alot when it was overheating, and nothing would get the temps down and stop it from smoking.

Apparently it won’t let me add it on mobile, it sounds someone blowing a whistle.

its an 04 Civic EX, 1.7L Engine, 132,xxx miles. I’ve owned it for 3 years but between 6 months and a year ago I have had all belts, spark plugs, ignition coils, and coolant tubing replaced. Going to have all fluids flushed tomorrow as I haven’t had it done, as well as an oil change and filter replacement. Hopefully it’ll fix the issue and I don’t need to sink a lot of money into a repair.
