Rich Posted January 7, 2008 Share Posted January 7, 2008 Well to cut things short, recently I have noticed a high pitched wering sound coming from the engine bay. Its in the area of the alternator. I am wondering if it is the alternator its self or could it be the water pump (possible because it reminds me of my shower when you leave it running too low ). Hopefully it might just be the belt (but wouldn't that be a squeak)Has anyone experianced this before and come to a diagnosis?Thanks in advanced.Rich. Quote Link to post Share on other sites
Stevie B Posted January 7, 2008 Share Posted January 7, 2008 spray ya little dw40 on the alternator belt mate, works a treat S. Quote Link to post Share on other sites
Rich Posted January 8, 2008 Author Share Posted January 8, 2008 Ok might try that, hopefully wont make things worse. It doesn't sound like its coming from the belt though. More so the alternator itself. Well if anyone needs help with the sound it makes, It sounds like its bloody supercharged!!!! Quote Link to post Share on other sites
Mart Posted January 8, 2008 Share Posted January 8, 2008 I have this aswell lad, Same area, Does your pitch increase when you give it a bit more excelleration? Quote Link to post Share on other sites
Stevie B Posted January 8, 2008 Share Posted January 8, 2008 trust me, it wont make it worse!oh and theres nout wrong with the sound of a supercharger S. Quote Link to post Share on other sites
Rich Posted January 8, 2008 Author Share Posted January 8, 2008 I have this aswell lad, Same area, Does your pitch increase when you give it a bit more excelleration?Yeah it doe, It also get a bit quieter when it warms up because the revs drop.trust me, it wont make it worse!oh and theres nout wrong with the sound of a supercharger S. well its a bit annoying when people ask if its supercharged and you say no I spose the look on their faces is a kodak moment I'll give it a try anyway. Mechanic coming over on thursday to have a look aswell. Quote Link to post Share on other sites
Mart Posted January 8, 2008 Share Posted January 8, 2008 Cool mate, Let me know how you get on with the mech?Mart... Quote Link to post Share on other sites
Rich Posted January 9, 2008 Author Share Posted January 9, 2008 Will do mart.@Steve: Wouldn't spraying WD40 on the belt make it squeak. Also would it be worth while spraying the wheels that turn with the belt? Quote Link to post Share on other sites
59bhp Posted January 9, 2008 Share Posted January 9, 2008 i got this exact same thing, ill be changing my alternator and water pump shortly so will let you know if it makes a difference. If it doesnt then it might be turbo related but the noise doesnt seem to be relative to boost pressure so im hoping its not that. Quote Link to post Share on other sites
Rich Posted January 9, 2008 Author Share Posted January 9, 2008 If it is turbo related, where would mine be located because its not in the usual 'bolted to under manifold' place just messing...It is definatly coming from the area of the alternator or water pump, I tried bleading the water system but that didnt really do much.

StarletRick Posted January 9, 2008 Share Posted January 9, 2008 do NOT put wd40 on a belt..... for one its flammable. and secondly because its a lubricant. why lubricate something where friction is critical. best cure for a squeaky belt is chalk. Quote Link to post Share on other sites

Rich Posted January 9, 2008 Author Share Posted January 9, 2008 Its more like a sucking sound than a squeak. Quote Link to post Share on other sites

Rich Posted January 9, 2008 Author Share Posted January 9, 2008 I definatly sounds like its coming from the alternator. Its weird, it was working fine and then as soon as I stripped it out it started making the noise Quote Link to post Share on other sites
Stevie B Posted January 9, 2008 Share Posted January 9, 2008 well hope you find out the problem anyway that is how i cured my annoying squealing sound.S. Quote Link to post Share on other sites
Rich Posted January 11, 2008 Author Share Posted January 11, 2008 Well my mechanic briefly looked at it as it was slightly pissin down yesterday. He tried spraying WD40 onto the belt but that didn't work (didn't make it squeak either) he said take the belt off, start the engine for a couple of seconds, if it still makes the sound then the engine is fergugered if not take the alternator off, clean it up and spray wd40 on the moving parts (he thinks it could be the baring) Quote Link to post Share on other sites

Water pumps the same believe it or not. Im unsure as to wether my noise is the same as whats been said here. Quote Link to post Share on other sites
