Dale SR Posted December 23, 2012 Share Posted December 23, 2012 hi, this sounds strange but if i have my lights on and say the heater at the same time then starlet squeaks like mad i think it must be something to do wi the altanator because its only when am using the electrics she squeaks. I've had a couple of ma mechanic mates look but they cant find a diagnosis can some1 help me, (its getting really embarrassing driving through town) Cheers, Dale Quote Link to post Share on other sites
Simon Posted December 23, 2012 Share Posted December 23, 2012 Change the belt they are only a few quid, it's probally a bit loose and when you put the extra load on the alternator it's making it slip. The only other thing it could be is the bearings in the alternator itself but you would usualy hear them all the time. Quote Link to post Share on other sites
Dale SR Posted December 23, 2012 Author Share Posted December 23, 2012 already got alternator belt changed and tightened an didn't fix it. Quote Link to post Share on other sites
Matt1878 Posted December 23, 2012 Share Posted December 23, 2012 I had a loud squeal yesterday as I set off out.. It was cold out and cold engine too. Worth changing a belt or just put it down to the weather? Quote Link to post Share on other sites
Dale SR Posted December 23, 2012 Author Share Posted December 23, 2012 its not like she dose it the once, as soon as u like use the electric window it ill make her squeak, or say its night time an the lights are on, a drop a gear she will squeak, daytime she dosent do it atall but thats cuz ma lights are off. its messed up like lol Quote Link to post Share on other sites

Simon Posted December 23, 2012 Share Posted December 23, 2012 Have you got stock pulleys on it or lightweight ones? Quote Link to post Share on other sites
Dale SR Posted December 23, 2012 Author Share Posted December 23, 2012 no sure what they are bud am a alloy wheel doctor no a mechanic lol Quote Link to post Share on other sites
Dale SR Posted December 23, 2012 Author Share Posted December 23, 2012 av no changed anything over to lightweight parts cars prity much standerd Quote Link to post Share on other sites
enots Posted December 23, 2012 Share Posted December 23, 2012 mine used to do it belts loose,if its new its probably stretched a little as they do better to tighten it as it constantly squealing will cause it to snap and you dont want that as it runs the water pump too if i remember rightly Quote Link to post Share on other sites
Dale SR Posted December 23, 2012 Author Share Posted December 23, 2012 i ill get it tightened again, see if that works, cheers , an ye dinny want that bursting just replaced the water pump a month ago , lol Quote Link to post Share on other sites
Dave277 Posted December 27, 2012 Share Posted December 27, 2012 HiMy daughters Starlet has had similar symptoms for a month or so, it only squeals when accelerating from low revs with the heated rear window and lights on.Thought it was the fanbelt, but found that the squeal is coming from the crankshaft pulley (harmonic balancer). The outer circumference of the pulley is separated from the inner by a thin rubber stripThe bond between them has broken so the outer can slip on the inner when the alternator is loaded.Replacing the pulley doesn't look too difficult assuming it comes off ok, but have had no luck finding a replacement so far. Hope this helps with your problem, be great if anyone can advise on best (cheapest!) place to get a replacementThanksDave Quote Link to post Share on other sites
Turbo Goose Posted December 28, 2012 Share Posted December 28, 2012 Mine doesnt squeek when my cars heating up (above 900rpm) but as soon as the car settles after 10 mins or so it squeeks on tick over. Goes a little worse when using electrics, mainly because the revs drop off a tiny bit. Done it even since ive owned it so never really bothered me.the main thing annoys me is the very bad knocking noise that sounds like my bottom end but you cant hear it when outside the car? Explain that one Quote Link to post Share on other sites
Dave277 Posted December 29, 2012 Share Posted December 29, 2012 Haven't been able to get hold of a new crankshaft pulley but took the old one off this morning and rebonded the rubber vibration dampening strip to the pulley inner part. Runs quiet now with no hint of a squeal.Think there must be a few Starlets running around with the same fault - the squeal is annoying, but it didn't look like it was going to fail any time soonKnocking noise could be related - bit of a long shot, but the pulley runs very close to the timing belt cover, maybe it could become loose enough to rattle against it?

loguey Posted February 9, 2013 Share Posted February 9, 2013 I have the same issue yet im running a lightweight bottom pulley, i find a squirt of wd shuts it up for a few days but im putting it down to it being so cold. its a new gates belt and has been on since about july, retightened to 1/4 of a turn, im just finding myself having to turn all electrics off apart from lights before i start engine braking. I have heard there is an aerosol that prevents belts from slipping Quote Link to post Share on other sites
