Where is the low side service port on 1998 olds cutlass?


Wiki User

The low side service port is located behind the generator and beneath it. Follow the sepentine belt to the generator and look below the belt close to the fire wall. Find an aluminum pipe with a valve cap. The red cap close to the radiator is the high side.
