How do you put a Serpentine Belt on a 1998 Olds Cutlass Supreme?

Not knowing what engine you have in your Olds, most engines will have the "Mapping" of the belt located somewhere under the hood. On my two Olds, they are located on the valve cover. When you purchase a new belt for your car the cardboard holder for the belt will display several diagrams based upon the engine that the belt will fit..... you out.

Where is the PVC valve located on a 1989 Olds Cutlass Supreme?

"Remove this only when cold (caution injury & vehicle damage" It is under your engine intake manifold plenum (the to metal assembly on the engine) almost center of the valve cover on the rear bank (closest to the fire wall). To change this you must rock the engine forward. You may need be able to remove this w/out removing the intake manifold. If you do be very carefull of the spider web thin vacuum lines under the manifold. If you remove the intake manifold you may need to purchase the intake manifold and any other gaskets and seals.

How do you properly bleed cooling system on 1996 olds cutlass?

To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.
