Strange Faint Noise on Ignition When Engine Cold Sign In

2006 Chevy Equinox LT, 3.4 L engine, 64,000 miles, regularly and faithfully maintained

On startup and until it fully warms up car makes a strange noise when given gas. It seems to be coming from behind the steering column, I can't hear it when the window or door is open over the engine noise. Sounds like a cross between sucking through a straw and a small animal scratching on something, or maybe plastic beads falling through a pipe. Car runs normally otherwise, no check engine or other warning lights, no smells. Need to know if it's something that can wait a week until I am able to leave it with a mechanic. Only 64K miles and I keep up with regular maintenance.

I don't think this noise will be isolated as to what without help (a real tech best) hearing this in person. You can't maintain a steering column BTW except not abuse it physically.


Miles don't mean much if a part broke it broke newer or older,

Well, thanks for answering. I took it to my mechanic last week but it wasn't making the noise by the time they got it and didn't when each of them test drove it. Due to my schedule I absolutely can't leave it until next Tuesday night for them to listen to it cold in the morning. I'm just hoping it is something that will hold together until then.

Murphy's Law - It wont do it when you want it to - figures. Yes drop it off so they have it cold ASAP. I can't say if safe or not at all. Most things to do with steering unless wildly broken or worn you can still steer.


Your schedule tight and understand. Understand also your whole schedule means nothing if this disables the car or causes an accident, hurt or kill someone! So can about anything that moves so hard to say for this situation,

Car's been sitting at the dealership all day, they pressure tested it and think it's just the radiator and overflow tank caps being old. They're pressure testing with the new caps tomorrow. So if anyone else has this symptom -- gurgling in the dash on cold start until car warms up, and has no other proof of leaks or head gasket issues, then have your caps checked. Much cheaper than replacing the head gasket!

? "Gurgling in dash" can be low coolant or air/vapor running thru heater core. Pressure caps can cause low coolant level and many vehicles are hard to fill either takes time and attention or faster with a vacuum fill machine then this game could be either over or if it returns have better info for diagnosing it,
