PT Cruiser 2001 Base Squeeling Sign In

2001
CHRYSLER
PT CRUISER
106,000 miles

So, winter just turned to summer and I noticed a squealing sound that wasn't there previously.

When I get the RPM's to about 2,000 I hear a high pitch squeal. The pitch is so high that most people can't even hear it. People look at me like I am crazy and just hearing things. Once I get up to 3,000 RPM the noise disappears.

During the colder mornings / days the squeal is not there at all. It's only on warmer days. I don't hear the squeal at all in Park or Reverse. I can only hear the squeal in drive.

I'm going to assume it's one of the belts but I am no where close to being a smart guy with cars. I'm just looking for some general advice on how I can diagnose this issue.

I had the main serpentine belt replaces and the pully tightened last year around this time. It's a very similar issue, however, It doesn't make the noise all the time like it did last year.

Noises are near impossible to diagnose over the internet. Have you had your mechanic take a look at it?

No. Not yet. Waiting for the warm to come along a little better so if I am without a car for a bit I can walk to work comfortably.

I need to get a small break line leak fixed soon so I'll just have them check out the squealing as during the same visit.

Re: PT Cruiser 2001 Base Squeeling Sign In

Just a wild thought: You said doesn't do this in park or reverse? So if only drive perhaps a motor mount allows too much motion with forces that way and something rubs by hair and temperatures matter somehow as well.


Sometimes you can run engine with hood open and see the engine while running, brakes applied well just shift and can see it move. May take a little throttle to show better and of course all caution doing that, that nothing is in the way of the vehicle or overdo that test alone. Get helper that is qualified if that is suspect to peg down or watch a mount separate that way or other ways,

I had all the motor mounts replaced last year at the same time they replaced the serpentine belt and tightened the tension.

Re: PT Cruiser 2001 Base Squeeling Sign In

I suppose it's possible. I purchased the car used last year. I took it to get it checked out to find that all the motor mounts needed replaced. I took it home and shortly after I noticed a similar squeal that I am having now. I took it back and they replaced the belt and tightened the tension. Fixed the problem all summer through winter.

The squeal is somehow different this time though. Before it didn't matter the RPMs I was going. Now it's only noticeable between 2000 and 3000 rpm.

Re: PT Cruiser 2001 Base Squeeling Sign In

You said they tightened the belt? Could be wrong but this shows only one engine available, one belt and it's self tensioned so what really happened?



That "tensioner" self adjusts to the limits of a belt. You could have a noise or problem with that and just do a belt while there but if that info in correct you do NOT adjust this belt.


Mounts? All of them, one or what? Were they separated or why were they declared bad?


Belts in general: Some just stink and are noisy and some are not. Most if belt is making the noise will shut up for a short while if you have the noise expected, shut off engine, just mist the belt ribs with even plain water and start it. If gone or much worse that points to a belt that just isn't good enough. Not conclusive of much if no change.


If you do this don't soak everything just pin point ribbed side of the belt. Hot parts and electrical thing do not and should not be exposed to water so I said ''mist spray'' not soaked with a hose type thing,

You have a leaking brake line and you're driving it around? Do not wait for different weather. Get a coat and walk if you have to. It amazes me that you are worried about a sound so small other people that ride with you cannot hear it, yet disregard a critical safety issue whereby by driving this car you are placing in danger everyone around you.

Screw the noise, fix that brake line right now or park it.

The leak is in the reservoir and not the lines itself. So break fluid leaks from the reservoir but stays in the lines.

They said they adjusted the tension, as I said before I am far from car smart so I had no idea about the auto tension. But after some more investigating it's more of a whistle than a squeal. I had a few people listen to the sound It sounds like a squeal to me but everyone else thinks it's a whistle. And now that i've been messing with it more it makes the noise in park, neutral and reverse it's just barely audible. You mainly hear it in drive.

They replaces the serpentine belt and replaced the tensioner according to my receipts.

As for mounts it was 1 upper and 1 lower mount that was replaced according to the receipt.

Re: PT Cruiser 2001 Base Squeeling Sign In

Belt tension - probably just a mix up of understanding so forget that. I was thinking you were catching bull just to quiet you down.


Back up on this and pay attention NOW on the brake line. They don't even have to give you a warning and usually don't but just boom and about ZERO brakes all when it's the worst possible time. Rusted out line is so common don't think it's just one piece but let a shop decide on overall lines all over it (under it) and do as much as needed. Line is cheap but some are a pest to route back in place perfectly and bleeding required may bust off bleeder or a domino effect of items needed to get those right and there's no choice it that or park it as Nick said,

The leak is not in my lines, but in the reservoir itself.
I've been told they have some sort of rubber seal in them that "can" dry out and crack. I'm assuming that's where the leak is. My lines do not loose any pressure. I've let the reservoir run completely out of fluid and drove with it on empty just to see if the lines are loosing fluid. I own a lot of land so I used it to "test" my theory.

Re: PT Cruiser 2001 Base Squeeling Sign In

You can try to justify driving it that way all you want but fluid loss is fluid loss and it can suddenly give out altogether with no warning. You don't ignore brake problems. You are endangering everyone else on the road with you.

Re: PT Cruiser 2001 Base Squeeling Sign In

Issue ended up being a loose hose going to the air filter.

Got breaks fluid leak fixed, was some sort of seal in the main cylinder.
