stevey425 Posted November 20, 2009 Share Posted November 20, 2009 Just bought this baby from an old retired dude down in San Diego. Love the car...it's in great condition, however I've just started noticing a short "buurrrraammp" sound right after the motor starts. Listen for yourselves--check out my video. Perhaps someone has experienced this condition and can let me know what system is affected and if I should be concerned. Thanks, Steve http://www.youtube.com/watch?v=U6d0VyY4ACE Quote Link to comment Share on other sites More sharing options...
Will B. Posted November 20, 2009 Share Posted November 20, 2009 Sounds like a fan to me, but I have 0 mechanical skills so hopefully someone else will chime in. Quote Link to comment Share on other sites More sharing options...
stcist2 Posted November 20, 2009 Share Posted November 20, 2009 does it make this noise every single time you start it hot and or cold/>? have you tried starting with the ac turned off? could be a timing belt tensioner letting the timing belt chatter,possible waterpump siezing very strange indeed need to listen with the hood open and try to find a general location of where the noise is coming from, could help alot Quote Link to comment Share on other sites More sharing options...
stevey425 Posted November 20, 2009 Author Share Posted November 20, 2009 happens hot or cold, ac has been off Quote Link to comment Share on other sites More sharing options...
SW03ES Posted November 21, 2009 Share Posted November 21, 2009 How many miles? The squeaking is the belt tensioners and that goes away once they warm up, but that noise you describe concerns me... Quote Link to comment Share on other sites More sharing options...
Just hanging on Posted November 22, 2009 Share Posted November 22, 2009 Sounds suspiciously like a squeaking drive belt. Before I'd invest in anything else, I'd try some belt dressing from your local auto parts store. Quote Link to comment Share on other sites More sharing options...
eatingupblacktop Posted November 22, 2009 Share Posted November 22, 2009 I hear two sounds that are off. The squeaking immediately after startup and continuing can be a belt or pulley and can be easily determined. The second is a delayed "flutter" like sound. Easy to speculate but better to determine the source by locating it. A "mechanics stethoscope" would be usefull here. Quote Link to comment Share on other sites More sharing options...
mann777 Posted November 23, 2009 Share Posted November 23, 2009 I had exactly the same noise, not to worry, Just replace the following parts in order. Parts Needed: ■Timing belt ~$52 ■Water pump ~$155 ■No.1 idler pulley ~$98 ■No.2 idler pulley ~$62 ■Timing belt tensioner ~$40 ■Thermostat - ~40$ Optional Parts to Replace: ■Spark plugs ■Spark plug wires ■Distributors ■Rotors ■Drive belt ■Air filter You will peace of mind, after that. A new lease of life to the car. Quote Link to comment Share on other sites More sharing options...
HomieG Posted November 23, 2009 Share Posted November 23, 2009 Don't just throw parts at it...diagnose it and fix the problem part(s). And experienced mechanic may be needed if you can't find the cause yourself. Throwing parts at the problem does not give a new lease on life, no matter what anyone wants to sell you. And please post your findings here! Quote Link to comment Share on other sites More sharing options...
FatherOfFive Posted December 3, 2009 Share Posted December 3, 2009 My 04 LS430 is making the exact same noise. It is definitely A/C related, because if you start the car without the A/C on (note: having the climate controls on 'Auto' is the same thing as having the A/C on) - you will not hear the sound - but you will hear the sound when you turn on the A/C or press the 'Auto' button. I also would like to fix this problem but I am not willing to replace a bunch of crap that isn't broke to fix it. Anybody else have fix to this problem that specifically addresses this problem? Thanks FoF Quote Link to comment Share on other sites More sharing options...

landar Posted December 3, 2009 Share Posted December 3, 2009 There are three distinct sounds: engine (normal), serpentine belt (squeaky) and a "machine gun-like" burst that goes away. The machine-gun burst is the worrisome noise. It sounds to me like it might be related to the A/C compressor/clutch or power steering pump. Since you are most likely going to replace the serpentine accessory belt(you ARE, aren't you? hint, hint) because of the squeak, I would be tempted to take the belt off, then start the engine (only let it run briefly). If the machine gun is still there, we can rule out anything run by the belt. Conversely, if the noise is gone, you can concentrate on accessories.
