Drive belts making squeaking noise on 86 oldsmobile cutlass supr

Your belt tensioner is possibly bad which could cause it to slip at low rpm.

mcdevito75 here, I don:"t think there is a fan belt changeing diagram for your 86" you can order the new belts and mark them Water pump, alternator, power steering. as you order them. The power steering pump is the most difficult to loosen and tighten, you"ll also need a crowbar to hold the various units tight after you install the new belts as the belts can"t be too lose nor too tight. Best bet let your local shop change the belts they last a good while and you have the piece of mind all is adjusted correct.

It doesn't have any marks. Make your own before you remove the belt. If the belt was broke or you already removed the belt then you will have to remove the valve covers and install specialty tools into the ends of the camshafts to line everything up correctly.

better off with a electric choke, and make sure the vacuum choke pulloff is working ,

check belt for correct tension then check pulleys bearing or a unit needs attention or level fluids --power steering pump-water pump -alternator-a/c

age does not matter, if ride is bumpy and things are making noise, get it checked out at shop. if you are happy with the comfort of the ride, all is good.

check timing belt

for the most part there is a diagram under the hood showing you how the belt goes on try this website www.autozone.com to see if they have your car listed

That could be only two things one a bad pistion or a bad rod. I would take the engine apart and find one or both maybe broken or in bad repair fixing. I would not drive it far it will throw the pistion or rod right through the engine costing ya more money or a new car.

Choke coil & adjustment should be on side of carburetor.
