Hi all, I did a search but didn't see anything related to this

I just bought an 04 G35 as a project car for Nissan Sport Magazine. I am gonna develop brake coolers for it (www.fourproducts.com) anyway, here is my question:

There is a slight whining noise coming from the front of the engine that the company that I purchase the car from has to resolve. At first I thought that it was a power steering pump, but it doesn't change pitch when you shift the wheel - it sounds like that though. A whine. It did get better after I drove it for a little while. It follows engine speed and sounds like it is coming from the front passengers side of the engine.

Any ideas?

Thanks,

Joe

 

Might be a belt tensioner. I had mine go outt and was replaced under warranty.

 

I am thinking that it is something like that.... thinking, hoping....

Thanks,

Joe

 

Bingo,

It was a belt tensioner. It was replaced and whine is gone now - thanks for the post.

which belt tensioner was it. The A/C or alternator?
