making a squeaking sound when go above 3rpm

[car95freak]

hey guys ok whenever i accelerate and go over 3 or 4 rpm or when i step on the gas like floor it and after it goes over 35 it makes like a squeaking sound. im thinking my chains are loose and need replacing. If thats the problem how much will that cost to do the whole chain job on the car. If thats not the problem wat is it and how much will it cost to do it. thanx joe

Belts or idler pulleys, not chains. Pretty cheap if you do it yourself.

idler pulley could include water pump in this case. bearings squeal when they're about to go.i take it you mean 3(x1000) =3000 rpms?

Please replace all three (four?) of your pulleys NOW.

Pulleys are cheap to replace, takes probably 30-45min labor. If you wait until the pulley seizes, the belt will snap off, stop turning the water pump, and overheat your motor and leave you stranded.(This happened to me last year.)

Have the water pump examined as well.. see if its making any weeping/whining noises. Whats the mileage on your 95 Q?

same thing happened to me as Jesda.

Maybe he was hand turning it to get "3rpm".

If the pulleys were sqeaking then, one would think it would have been obvious to him.

the car has about 160 the odometer broke vefore i got the car but it wasnt taken very good care of though. so i should replace all the pulleys or just the belts. and also do i have to replace the crank pulley as well or noo? also when a car wityh lets say about 150 to 170 wats the things that i should replace or look for?

[car95freak]

alos how much am i looking at for new pulleys if i put them on myself?

[Jesda]

You do not have to replace the crank pulley.

For the parts:http://www.everythinginfiniti.com/Would be easiest (imho) to just call them at 888-216-5328. You can talk to Joe or anyone else in the parts department and they should be able to tell you which parts you will need.

I dont recall the price of the pulleys off hand, but I'm perpetually broke, and they arent that expensive to me.

You may want to do a search (red button, upper right) for "transmission flush q45" or "transmission flush q45" -- there's a lot of debate on when to flush the transmission, whether to flush the transmission, and how to properly flush it.

Do you have an external transmission cooler installed? Search for that too.

Happy motoring.
