Chattering from under the hood

Matt · 10-14-2002, 07:29 AM

On my brothers '92 SC, there's a chattering noise from under the hood. We thought it was the clutch since it was getting bad anyways, he go it replaced and the noise is still there. It's hard to locate the source of the noise. Another thing sometimes when the engine is not all the way to operating temp. it sort of has a sluggish pick up but once you hit 4K RPMs it kicks in. What could be the source of these problems?

Does he feel a vibration in the pedals?

No, I don't think so.

Could it be the water pump? Mine just went out and I think it was chattering a bit. Sounds better after replacement.

Try to determine at least which SIDE (passenger or driver's) the noise is coming from. A quick way to test if it is a bad alternator/water pump/power steering pump/ a/c compressor or idler /tensioner pulley is to remove the belt. Then start the car with the belt removed for a minute or so and see if the noise goes away. If it does, something driven by the belt is making the noise. If it does not...repost for more suggestions (some scary and expensive ones too)

Alternators been replaced so that's not it. I'll try checking without the belt.

does the chattering go away when you come off idle? say like when you give it a little gas?

Yep get more info or what side of the car its coming from. But I will go out on a limb and guess the tensioner
