I have a bad starter (definitely not the cause of the problem) and a bad radiator fan motor (?). Throughout the winter, the radiator fan would continue to spin (or whatever) a few seconds after the car was turned off. Now it does it for 5 seconds, and it does it the whole time the car is on. It sounds terrible.

People I know have asked me if my car was breaking down or if it was okay.

I just recently hit 170,000 miles and this is the second problem I've had with it (mechanically) other than spark plugs.

Anyone have any ideas or have any validity towards my thoughts?

I'll post videos soon.

 

I had a bad radiator fan and when it turned on the whole car shook and it was a horrible grinding sound.

$80 later, replaced the whole assembly (from ebay) and it is super quiet now. Lost of posts on this.

 

this happened to my car as well I fixed it for about the same price and no more noise. I have a 2000 maxima se

 

unplug the fan harness and see if the noise goes away. IMO that would be the best way to find out if its a fan.

 

Had my motor fans go bad on two of my maxs. First one took to dealer, charged me 400 bucks. Second car, i wen to ebay payed 80 dollars and did the 10 minute job myself. As previously mentioned, unplug your radiator fan motors.

 

Same here, although I bought two new fan motors at AutoZone for just $60 each. Took all of 20 minutes to replace them both. Grinding sound has been gone ever since. An easy fix.

 

Will unplugging these for a while cause any damage to my car? So can I leave them unplugged, or just do it temporarily to make sure it's that? I'll have to wait until it happens again.

 

only a temp thing. unplug and if the noise stops plug back in if you must drive and go get new fans.

 

you can unplug each fan individually and find out which one it is. I'm in Texas and drove for a week in 100 degree weather with one fan unplugged.

 

If you're sitting inside the car, it's the fan on the right. If you're on the outside standing in front of the car, it's your left.

It happens after a while in cold weather, but if it's warm out, it happens when you have the AC on.

 

maybe your car is actually grinding meat.

 

Maybe that's a good thing?

 

LOL^^^^^

 

explain to me the instance where a maxima that automatically makes hamburgers would be a bad thing.

 

If they were too well done? Without cheese? I can only eat a medium-rare or medium hamburger with cheese (thus, a cheeseburger).

 

Just change the fan motor and the noise will be gone
