I hadn't started my jeep in about 3 days and this morning I went to start it. It didn't start the first two times but it fired right up the third time. The weird part was that it started making a really loud squeal that sounds like its coming from around the passenger side firewall. It sounds like one of those squeaky wheels and it will get louder and louder and then faster and then it will just stop. It did it again after school only this time I had only turned the ignition on (motor was NOT running) and it made the same squeal. It would do the same thing. If I turned it off right after then started again it did NOT squeal. If left alone for a couple hours it WILL squeal. What could this be?!?!

 

Check your belts

 

Do the belts even turn when the engine is not running?

 

Honestly, I'm not a mechanic so I'm not sure, but if my engine was making a noise like that the first thing I would look at would be the belts. Not sure what else it would be, does it sound like metal on metal?

 

sorta, its hard to explain. its like a squeaky wheel it has a high pitch then the pitch of the squeak goes lower then up again

 

Belts don't move when engine is off....

 

Do you have the fan motor on?

 

Does the squeak get higher when the rpms go up? Like when you step on the pedal?

 

it didnt seem to get higher as i accelerated. the electric fan was not on

 

good to know.

could it be a bearing?

 

I have no idea. im just confused as to why it was making the sound when the engine was off. maybe the fuel pump? but i dont know

 

is it the heater fan motor?

 

He said fan wasn't on... so it squeaks when you turn key to accessories? Just starts squeaking? weird...

 

actually i tried starting it with the heater fan on and the noise seemed to go away. not sure if it was a one time thing but i will keep it posted just in case it comes up again.it bugs me that its doin this though. its such a weird problem
