Excessive Oil Loss (G.M. Models Only)

If system has lost excessive oil, remove the accumulator, drain and measure the oil. If more than 3 ounces is measured, add same amount of new oil as was drained. If less than 3 ounces, add 3 ounces of new oil. If a new accumulator is being installed, add 1 additional ounce of oil to replacement accumulator.
