2007 civic si coupe My 2007 civic si is making a whining noise, sounds like it's supercharged when accelerating, i was told it might be low on power steering fluid, but it's and electrical steering system with no power steering reservoir. New to the Si and have no idea what it could be. Has anyone else had this issue? Or how to fix it? Or is it normal in a Si? Any advice is greatly appreciated, thank. |
Re: 2007 civic si coupe Check trans fluid |
Re: 2007 civic si coupe I've already done the transmission fluid flushed and replaced with new synchro mesh oil |
Re: 2007 civic si coupe Why didn't you put the proper Honda fluid in? |
Re: 2007 civic si coupe Mechanic recommended synchro mesh and I've seen it used before, car had smoother shifting after old oil was replaced, but whining noise remained |
Re: 2007 civic si coupe Si... manual? |
Re: 2007 civic si coupe Yes, 6 speed manual |
Re: 2007 civic si coupe go to a transmission shop and get an estimate. if suspicious estimate, come back here |
Re: 2007 civic si coupe An estimate on what? I've already taken the car to a transmission shop, thats where they did transmission fluid flush |
Re: 2007 civic si coupe well, you did not specify it was a transmission shop - can't know from my monitor... |
Re: 2007 civic si coupe My apologies, i just want to know the source of the whining noise, from experienced Si owners or ppl who have experienced similar issues |
Re: 2007 civic si coupe Potentially the previous owner or you did not maintain the trans fluid properly, it got dirty and wasted a bearing. Need to either take it back to that shop and have them listen to it or take it to a different shop. I still feel you should have the proper fluid in it, but I doubt it will get rid of the noise |
Re: 2007 civic si coupe I took the car to a very trustworthy transmission shop where i live, 2 weeks after i bought it, trans fluid wasnt in bad shape, engine oil was a little dirty but not bad either and spark plugs were in good shape, had everything changed either way, engine is steady on idle, car does run strong, just the whining noise |
Re: 2007 civic si coupe How sure are you it's coming from the transmission? Could be something on the accessory belt (A/C, alternator, tensioner, idle pulley). |
Re: 2007 civic si coupe I didnt say it was transmission, just mentioned the whining noise, and was looking for advice from more experienced si owners |
Re: 2007 civic si coupe Don't own an Si but I am fairly knowledgeable with the K series engine. I haven't heard of any common issues that would cause a whining noise. On my car I did have the idle pulley bearing start making a noise most notably when accelerating. This is the pulley at the top, where the power steering pump would be on other K series engines. Don't know how much troubleshooting you've done but you really need to pinpoint where it's coming from. This can obviously be very difficult or impossible if it's not loud enough. Mine eventually started making a little noise at idle so I was able to determine the origin. I would suggest removing the accessory belt as a test to see if the noise goes away but the would not work on the K series. The water pump is driven off the belt. You could remove the belt and spin all the pullies by hand to see if one doesn't feel smooth. |
Re: 2007 civic si coupe the first items about whining noise that comes when accelerating for any car (not Si related, any car) is bearings or transmission, so trans is one that popped up first. Could be alternator, power steering (not your case), AC, etc. Not likely to be axles/CV joint, they click when turned. Could be wheel bearings too |
Re: 2007 civic si coupe Thanks for the helpful advice, i will do some tests to see where the noise is coming from, have been short on time lately but will make time to test it, thanks again |
