this morning when i started my car, the engine made this whiny whistling noise, is that normal when it gets cold? i just bought my car, it only has 12k miles on it. i hope its not a big problem.

 

is it a whistle or a continous squeak? I get a continous squeak on a cold startup and it comes from the belt area. People on this forums tell me that the belt is loose or might require some dressing..havent had the time to take it to the dealer.

 

Its like loud continous SHHH noise, and it sounds like its breathing alot of air, maybe its the fan, im not sure, i just bought mine last week, damn nissan dealers.

 

mine does that but thats because i have an intake hehe...dunno about ur situation...never had that happen with my airbox in.

 

I've never heard a sound like that yet, i've heard a screech sound for a quick second at startup. As cold as it's been lately ( record low -12 sat. morn. here) your bound to hear some odd sounds.

 

Mine does that, I have an 03 with 9k. I don't know if there's a problem or not, just wanted to say that mine does that too.

I think the sound gets higher pitched when the rpms go up, is that the same sound?

Mine is all stock

 

When I had an Oldsmobile, a while ago, had such a whistling noise - next thing I knew was I lost all my coolant: water pump went out. Check out your coolant level.

(when a water pump goes out, it starts squirting coolant out through a special hole, and yes, it is in the belt area)

 

yes but when the water pump goes..you'll know as you'll hear it at cruising speeds and at acceleration. I doubt it's that..it can either by the OEM intake ( since it's cold outside and cold air is less dense) or its the belts.

 

...I thought cold air is more dense...

But you're right, it might be the throttle body whistle, or the pulleys.

 

It's not the water pump

 

mine is all stock, but it doesnt do it all the time, jsut once in a while, when it gets really cold, dont know what the problem is, i was just wondering if that was normal for other maximas

 

Does it whistle when you accelarate? If so, it's normal. Everybody 3.5 max has that whistle sound in 1st gear.

 

yeah it whistles when i accelrate, just wondering if other guys are having the same problem, ill just take it to the dealer if i have to.

 

If you only hear at startup, then it is probably the starter

check out this link - it makes a lot of sense because the grease probably does not last forever.

no, I asked this question when i was new and everyone said that their 02-02 has a slight whistle noise when they go through 1st.

 

Yep. Mine does it too.

 

it probaly is the grease on the starter, but i dont want to mess it up or anything, does it go under warranty??
