Repeat steps  2 and  3 of the INITIAL FLUSH procedure. Release the trigger (8) of the transmission oil cooler and line flusher and allow water only to rinse the oil cooler and pipes for one minute.
  2. Turn the transmission oil cooler and line flusher water supply valve (1) to the OFF position and turn off the water supply at the faucet. See Figure . Attach the shop air supply to the flushing system feed air valve (2) on the transmission oil cooler and line flusher, and blow out the water from the oil cooler and pipes. Continue until no water comes out of the discharge hose (5).
