strange screaching sound when starting the car

I just got my 05 s2000 but when the car is cold and I start the car, there is a loud shrieking sound. I was told this is normal, just need to grease the belts but nothing major if I don't do anything. Just checking with you guys to see if you have experienced this or heard of this.

by they way, our cd player is not standard 6 disc and only plays audio (no mp3s)?

If you grease the belts the screeching will go away...and your engine too most likely.

It's not normal to screech. It might be a loose belt or you may need a new one. Oiling it will make the engine overheat because it will be slipping.

Either you don't know much about cars...or this is a troll.

DO NOT GREASE THE BELT!!! A quick way to see if it is a loose belt is to put some baby powder on the belt and see if that quiets it up a bit.

I think he may be referring to the overstart but not sure. My car, like so many others on the forums, overstarts itself when it is cold. That is, I press start button for a second and release. The engine turns over and starts but the starter motor continues for a fraction of a second emitting a....well, screach like sound....

I'm not sure if it is overstart as I dont press the button long. It only happens when you first start the car. The previous owner said that he was told by Honda just to grease the belts every once in awhile. Not sure if it is normal.

I suspect the original advice was dress the belt, not grease the belt.
Do not grease your serpentine belt! You want your belts to grip, not slip.

You could get yourself a can of belt dressing. (A quick search on google revealed companies still selling variants of said garbage.) This is usually an areosol can of goo that you spray onto your belts to give them added grip on the pullies... More grip = less slip, which means no squeal. Its an instant fix, 'miracle in a can' type of product. But, just like Viagra, its effect is only temporary.

In fact, belt dressings of any kind may improve your belt's performance for a couple of days, or even a week or two, but the underlying cause of the problem won't be fixed and the screech will enventually come back.

A quick search on YouTube came up with a fairly entertaining, if misguided and rather adolescent, approach to quieting a noisy belt. It shows just about any sticky substance will work as a temporary band-aid. It also has a great recording of a persistently squealing belt.

If your noise doesn't sound like this, (for at least a second or two) then its probably not the belt.

And a screeching belt is sometimes due to excessive load on the belt, due to one of the driven components requiring abnormal torque. Like an alternator or water pump with bearings that have failed or are failing.

look for this marking. if the pointer is to the right of the indicator rib as shown here, then you need to change your belt

If it is any consolation.....my 04 makes the same noise. Mine is only a weekend driver and auto-xer, and only does it when I first start it Friday evening, and not consistently. No help....but I know exactly what you are talking about.

Things that go screech in the night.

Belt, throwout bearing, water pump.

If you put a little brake fluid in the coolant, it will quiet a noisy water pump

Yeah, I just started getting this sound as well, with my 03 and 125,000mi.

It's definatley not belt slippage. I know exactly what that sounds like. It's a mechanical screech sound, and the starter overrun sounds like a good explanation.

Getting cooler in the NE and I am starting to have this problem again...anyone else?

I dont think dressing belt is going to make a difference as the car clearly overstarts itself....

jyeh said "I'm not sure if it is overstart as I dont press the button long."

The duration of pressing the button is not causing the overstart. I only have to tap my button and the engine cranks until started. Somewhere, there is a sensor that tells ecu when to stop starter and that sensor is affected by temperature- I really think it is as simple as that... anyone have any additional experience/knowledge about this issue before I run it by the stealership?

Mine did it this morning as well. It was under 40 (unusual for oct in Sacramento). I didnt press the button long either. Car makes lots of weird noises. I am just happy that at 105K miles it passed its CA smog with flying colors!

my Ap1 did this also.....only on cold mornings, and only on start up.

it was the bendix (starter gear armature) on the starter sticking. you are hearing the starter gear riding on the flywheel for a moment after the engine is running.

if it only lasts for a split second, then not likely to be any trouble.
if it lasts longer, it will wear out the ring gear on the flywheel.

you could remove the starter, clean up and grease the bendix,
or just replace the starter all together.

Thanks Jagg!

Now I have to look into DIYs for starter replacement, I cannot imagine it is that bad.

You think aftermarket would be ok?...

It's the starter. Does greasing the bendix work to fix that screech?

I would try that before I replaced the starter.

I had the "screech" happen many times in colder weather, and it never turned into any kind of real problem......like I said, mine never did it for more than a split second.

The return spring itself may be weak on the bendix (if that were the case though, it wouldn't be temperature sensitive) , but I believe you'd have to manufacture your own replacement....I'm unaware of a supplier to purchase one, as pretty much all starter motors nowadays are not designed to be rebuilt by anyone other than a company that specializes in the process.

I've never read here on the forum of a case where anybody had to replace the flywheel on their S for this problem.......

jagg

p.s. aftermarket starter would be just fine.

To make a short story long here goes, I used to drive the old BMW Air head boxers engine. Once in a while when starting the machine, a growl was heard from the starter motor. It was caused by a bad starter bushing the bushing is located in the armature end of the starter .Excessive wear in the bushing caused the condition. My car also does this when it`s cold. I dont know whether our starters have a bush ,or a bearing. At any rate either live with the noise or replace starter. I ssprayed a small amount of penetrating oil between starter housing& bendix shell . seems better
