I have an alty GLE KA24DE all stock, nothing modified (except maybe exhaust is aftermarket, not sure, i bought it that way) but other than that nothing modified that i know of.

When i hit high rpms (over 5,500) and near closer to redline, my car makes a fairly loud whistling sound that what i've been told sounds a lot like a turbocharger (from people usually racing me with equal poopy cars). It doesnt really sound like it to me, i just hear a somewhat faint whistle. What i think it might be is some belts or something, but i honestly dont know.

any got any ideas?

thanks

 

its definately a turbocharger. no doubt about it.

 

Possibly exhaust leak.

 

1. pop your hood
2. start your car
3. put your head in the engine bay
4. lisen
5. make a guess as to were its coming from
6. fix what you think it might be


or

drive to a mechanic

 

rev the engine from the under hood and find the location of the whistle. It should be pretty easy to differentiate if the whistle is coming from the belts or the exhaust. belts take 20 minutes to change.

 

if its a belt just go buy belt conditioner and make sure its on there tight.

could also be a pulley my old alitma went through 2.

 

belt squeak or clutch fan doing its thing. If belt then follow what people said above to fix it. If the noise is the clutch fan then drive on or go with an electrical fan setup.

 

its an altima no clutch fan

 

lol thanks for reminding me that there are other vehicles than 240's in nissan tech.

most likely belts then.

 

exhaust leak.
