AHJGTA Posted March 18, 2008 Share Posted March 18, 2008 Hello I have a 1996 LS400 with 188000 km. Today I parked the car at work and turned it and heard a humming sound. Lasted about 3 seconds but frequenct. leaves a 2 second interval and then hooom. I though it sounds like a servo. Maybe the ventilator stuf trying to open or close. So I waited a few minutes. Still going. I did not want to leave it like that as it might drain the battery. So I disconnect the negative terminal. Noise still there. Disconnect the positive terminal. Still have noise. The battery is fully disconnected and that noise is still there. Or was when I left it. Half the way up I thought to try changing the parking spot. (This was a prime spot and I thought I was lucky to get it) but would have been late for work. Any help will be appreciiated. Thanks Quote Link to comment Share on other sites More sharing options...
RFeldes Posted March 18, 2008 Share Posted March 18, 2008 Could be your radiator. Make sure the levels are where they should be. Quote Link to comment Share on other sites More sharing options...
AHJGTA Posted March 18, 2008 Author Share Posted March 18, 2008 Radiator is a good idea. I'll check it tonight. The noise seemed to be coming from the front left. Could be your radiator. Make sure the levels are where they should be. Quote Link to comment Share on other sites More sharing options...

AHJGTA Posted March 21, 2008 Author Share Posted March 21, 2008 !Removed!!! :D Hey Mr. Mechanic. My car's farting, you have some antacid ? Or how about some anti-flatulent??? It wasn't me it was the car. Honest. Must be from all that ethanol we 're force feeding it! More like a burp though as it is coming from near the intake. The noise stoppped. Another one of these mysteries i got the same noise, its not radiator tho:) still not sure what it is, sounds like the car is farting:) i have this for few years now and did not cause any trouble so far.it might the vacuum system.
