Hi party people!
So there's a coolant line that runs from the thermostat to the intake manifold. That little line is making a weird high-ish pitched noise like the flow might be restricted going into the intake. Have any of you heard of anything like this? I have a feeling I'm gonna have to dump the coolant and remove the intake manifold and look inside the hose. I'm 90% sure it's coming from there... but before I start taking apart the engine, I'd like some input from those in the know! Oh... and the car has 57,000 on it.
