My car has this squealing noise that it makes when I first start driving it, only when I'm hitting the throttle.
It lasts for about 5-10 minutes then goes away, after driving.
However, warming the car up does not solve the problem.
I've already confirmed that it's not the timing belt.
There are 2 new axle assemblies on it, so the CV joints/boots aren't the problem.
I've recently replaced the plug wires and plugs, so I know they're current (although, I'm guessing that shouldn't create any issues like above).
I know I still need to do 2 things, but I'm unsure if it's a related problem. I'm getting my tranny flushed friday (fluid's brown, but no metallic pieces), and I have a twisted fuel line.
I was assuming it was the fuel line, but have been told by a couple shops that it doesn't seem like that would do it.
What'd you guys think?
Oh yeah, the sound is definitely coming from the front of the car.
Originally posted by amerikim Could be water pump beginning to go out or belt issues or check your power steering hydraulics. I think its water pump imho.
I hope not, the timing belt and pump were just recently replaced.
I'll have them checked though.
When the fluid is cold, there is more of a load on the pump. This causes the belt to slip a little (source of the squealing noise). After it warms a little, the pump doesn't create as much of a load and the belt stops slipping.
It's also possible it's the alternator. American cars do that a fair amount due to the load from the alternator.
Have the belts checked first. That's an easy and cheap fix.

You're absolutely sure it's not the timing belt? It sound like it could be tightened down improperly or to the wrong spec.
The belt was replaced shortly before I bought the car, along with the power steering pump. I confirmed this with a mechanic who looked over the car before I bought it (I bought it maybe a month or a month and a half ago).
I recently had it looked at while I went in for the fuel line to get checked out, and they said the timing belt was in fine condition and it wasn't loose at all.

I'll have 'em take a look at it when I take it in Friday for the tranny flush. Thanks, Meisner.
I got something really similar to that as well crawlingeye. Itd like a wierd vibration noise, no matter how fast I go I hear it. Its hard to tell if its coming from the wheel or from under the hood. I know for sure its near somewhere on the driver's side though. When I stop at a light it tends to vibrate causing a very strange knocking noise. When I drive and lift my foot off the throttle it makes this other noise as if I was going over a speed bump. Dunno what the hell it is. Any feedback is appreciated.
Why do you guys keep mentioning the timing belt??? The timing belt is a toothed belt and it controls the valve timing relative to the crank. It really can't be 'loose', per se. There is a tensioner that keeps it tight. But more importantly, if it was loose, he'd be having much worse problems than a squealing noise. It would run like crap.
He mentioned the power steering pump was replaced...that mean the p/s belt was loosened and retightened. That is a tough belt to get good and tight. I still say it's the p/s belt.

Exactly. The timing belt is toothed and is inside the engine; it's not one of those you see on the "outside" of the engine. A freshly installed "external" belt (alternator, P/S, or serpentine if that's what your engine has) is a prime candidate for just the squealing you describe. Such belts often stretch and limber up not long after being installed. It seems that this issue has improved with time, but ten or more years ago, a belt replacement was routinely a two-visit procedure. First, you'd get the belt done, then a couple weeks later, it would need to be re-adjusted. Get it taken care of soon. If this is the origin of your sound, the rubbing that generates the squeal can quickly cause "glazing" of the belt-pulley contact surface (from the heat and rubbing). This, in turn, can lead to early cracking, failure, and ultimately another new belt.
Originally posted by mykngdom4avvti I have to agree with the other people that posted. This is probably a timing belt. It might be a surpintine belt or an accessory drive belt. Possibly an alternator, or power steering problem.
Open the hood and stand infront of the car. Have someone start it.
Starting it won't replicate the problem. The problem occurs while I press once I start driving for the first couple minutes. Like I said, it goes away after about 5 minutes.
I checked my timing belt today for tension and gave it a surface eyeballing (without removing it) and everything appears ok. The belt below that (I'm unsure of what that one is for) seems to be alright as well, but I can't get a very good view of that at all.
The car goes in tomorrow for the tranny flush, so I'll see how everything goes after that.
Um....I don't think you're talking about the timing belt. Did you have to take off a plastic cover before you could see any part of the "timing belt"? The timing belt on any car is completely enclosed and protected by some sort of cover. It is usually difficult to remove these covers (many bolts that are tough to get to).
I belt you're looking at the alternator and A/C compressor belt and calling that the timing belt. The other belt you couldn't see too well is the power steering belt.
I'm starting to agree, Meisner. When I went out today and grabbed a flashlight, the power steering belt (smaller belt, kind of hidden) looked slightly worn (from what I could see from a distance). If not the mechanic, saturday my brother will be down (who is a mechanic himself) who will look at it for me too.
