O-rings must first be installed before joining the A/C accumulator to the condenser tube with the flow arrow facing towards the evaporator. You must attach the nuts to the A/C accumulator and tighten them to 15 N.m (11 lb ft). Put back the evaporator hose assembly and follow by evacuating the A/C system and recharging it.
