Question about 1997 Nissan.5 Altima
You helped me last time my radiator had blown a hole in it and come to find out the water temp sensor was bad. Replaced and all was good.
I have been on this site before and you guys and gals are amazing so this may be a good one for you. This is very interesting....
I have a 97 nissan altima with 175,000 miles. She is running great no smoke not miss no nothing but here is the problem: When i started up the car last week i heard a humming noise. This noise will stay in sync of the cars RPMs if i rev it it will rev right with it. I know its comming from under the hood but where im not sure???
I replaced the battery since it was old so i know that cant be it, i had the alternator tested and all is good. The belts are in good shape. i did notice that i was a little low on power steering fluid i topped it off but still have the same noise. I have let 2 different mechanics if you will lisen to it and one says that its probley the bearing in a pully and the other thinks pully in the motor running the timming chain. Now that to me is real bad news. So far i havent found a shop that i can trust yet so i guess that why im comming to you and trying to do most of this myself.
Let me know what your opions are and what i need to do cause u have earned my trust.
Look foward to your comments,
another bearing to look at would be the pulley bearing of the compressor or the tensioner or belt adjuster. these two bearings ( if you have them in your car) are sources of noises which are sync with car's rev.
tnx again 4 using Fixya,
