Drain the coolant from the radiatorand remove the coolant expansion tank (shunt) hose and fittings from thewater pump housing. Also remove the three P-clips from this hose that mountit to the engine and re-install the associated hardware. Only the hose,clamp, and P-clip hardware will be reused.Install the new hose barb elbow (CH7W-1890)into the water pump housing such that it points about 15° outward ofdirectly rearward (see below). Re-attach the shunt hose after re-routing itaccording to the photos below and trimming the excess length of hose (approximately3.5 inches, but will vary by machine).

After re-installing the alternator, the bracket(142-9826) for the mounting of the P-clip to support the power wire willneed to be re-oriented and modified to provide clearance for the new FEADbracket and rear debris shield on the alternator. See photo below.
Install the new belt (501178D1) and the newRH finger guard (501045D1). The LH finger guard (227-8227) will be re-used,but must be modified to provide clearance around the alternator. See picturebelow.
The outer three wires of the finger guard shouldbe bent in the area of the alternator to provide approximately ½"(13 mm) clearance with the alternator. Please take care to protect thepaint when re-shaping the wires on the finger guard.Be sure all shields and guards are installed.Operate machine for a few minutes and visually inspect the pulleys andbelts for proper operation. Recheck the coolant level and add extendedlife coolant as required.
