Super loud chirping noise when driving and idle - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

UNCC_BRZ · 08-22-2018, 11:09 AM

I am hearing a similar noise to this, it is only when the engine is cold, and gets worst up to about 3000 rpm, then goes away. And it is completely absent when the engine is fully warm. I replaced the belt <5000 miles ago, so I really doubt that its that. The TOB and clutch was replaced about the same time.

Can be TOB, does noise change with clutch in/out?

You can try removing belt and turning each accessory or idler by hand and listening for a squeak

Im going to tell her to do that as well.

I think for hers like its a cold start as well sometimes when its warm it does it need to make sure again since it isn't my car lol.

If it's consistently during cold start, then most likely the belt is slipping at the alternator pulley. Load on the alternator is greatest when it's dumping current back to the battery right after starting the engine.

You might also be able to get it to squeak by turning on all the lights and cranking the cabin fan on high as it idles.

So found the problem it was pulley that had some play in it we took it off and it was just no bueno but we cleaned it a tad bit and put it back on and made no noise like at all. She got the pulley though just waiting on it to come in the mail lol.

I recommend keeping it to short trips until you replace it.

Could frag at any moment.
