On the 1993 Oldsmobile Cutlass Ciera S ,V6, 3.3 some of the AC Compressors had O Rings & others used flat washers. That Year they used some with O rings & some with flat washers. I called the Chevrolet Dealer where I bought mine & that is what they told Me. The Auto Parts place said the same thing. You have to look at Your old Compressor to tell. Mine has the Compressor with flat washers!!
With a piston ring compressor.
i have a 90 cutlass ciera with a v6 3300 and just replased that. it is called a combanation sensor. its the crankshaft and cam together located at the back of the harmonic balancer attached to the block. it has 2 bolts on the right side holding it to the block a one in the middle to hold the sensor in place and the sensor sits in it and faces the harmonic balancer on the back of the interrupter rings
Place rings into their respective positions on the piston. Place ring compressor over rings and tighten up until you can only just move the piston inside the compressor. Place the top of the piston into the bottom of the cylinder, push the piston and rings up out out of the compressor and into the cylinder keeping the compressor hard against the base of the cylinder. If you do not hold the compressor hard against cylinder the rings will slip out and you start again, you are not allowed to throw the compressor at your garage door until the third time. You should try it without a compressor, or have you?.
My 1986 cutlass supreme w/307 was smoking bad, and I tore the motor down and the rings were shot.
Neoprene O rings as the insulator between the terminals and the compressor housing.
To replace the piston rings, you will nee to use a ring compressor tool or two pliers to remove the old rings. Place on the new rings, and scatter the gaps in the rings. Apply some engine oil to the rings so they are easier to get in place.
there is 2 o-rings at each connection
You have a leak. usually one of the o rings where lines attach to it.
The ac system will have to be drained of freon and the pressure released. Then the compressor can be removed and replaced. Replace all o rings along the way as well.
The system will need to be drained of Freon and pressure. Then the lines can be removed and the compressor replaced. Change all o rings during the procedure.
The collectr and all applicable o rings
It is a spring metal sleeve that goes over a piston to compress the rings so that the piston can be install in the motor. It tightens down on the piston, forcing the rings into the grooves in the piston then you tap it into the cylinder.
