4. Position fan shroud towards engine. Fan shroud does not have to be removed from vehicle.
5. Disconnect transmission cooler lines (if equipped) at radiator. Use quick connect fitting release tool #6935.





WARNING: constant tension hose clamps are used on most cooling system hoses. when removing or installing, use only tools designed for servicing this type of clamp, such as special clamp tool (number 6094). snap-on clamp tool (number HPC-20) may be used for larger clamps. always wear safety glasses when using constant tension clamps.
