HARRISON V5 5-Cylinder Drain & Refill

  1. If system is operable, run for several minutes to stabilize system before performing repairs. Turn off engine. Discharge system and remove compressor. See SERVICING PRECAUTIONS at the beginning of this article. Remove drain plug. Drain and measure oil.
  2. If more than one ounce is drained, add same amount. If less than one ounce is drained, add 2 ounces of new refrigerant oil to compressor.
  3. If A/C components are replaced, add refrigerant oil to system. Add one ounce if condenser is replaced. Add 3.5 ounces if accumulator is replaced.
  4. When replacing a component which has caused a large refrigerant leak, add 3 ounces of new oil plus the required amount for the part being replaced. Add oil directly to part being replaced if possible. If oil can not be easily added to part, add oil to accumulator.
NOTE: If oil drained contains metal chips or other debris, replace receiver-drier. Flush out system before evacuating and recharging.
