2. Loosen belt tightener (1) and remove the vee belt. 3. Remove four bolts (3), water pump (2) and the gasket.Install Water Pump
1. Put water pump (1), gasket (2) and the bolts in position. Tighten the bolts. 2. Put vee belt (3) in position. Adjust belt tightener (4) to get the correct tension on the vee belt.3. For correct vee belt tension see SPECIFICATIONS.4. Fill the radiator with coolant to the correct level.end by:a) install fan and fan driveDisassemble Water Pump
start by:a) remove water pump 1. Hold the impeller shaft with a wrench and use an impact wrench to remove nut (1) from the shaft. Remove pump adapter (2). 2. Use tool group (A) and a press to remove shaft (3), seal assembly and impeller from the water pump housing. 3. Remove spacer (4) and seal (5) from the water pump housing. 4. Remove snap ring (6) from housing with tool (B). 5. Remove spacer (7) and bearing assembly (8) from the housing. 6. Remove seal from the water pump housing with tool group (A). 7. Remove impeller (9) from the shaft (10) with tool group (A). 8. Remove the water seal assembly (11) from the impeller shaft.Assemble Water Pump
1. Put 2S3230 Lubricant between the bearings. Put spacer (2) between bearing assembly (3) and then put bearing assembly (3) in position on a press. 2. Put impeller shaft (1) in position and push it into the bearing assembly.3. Put a small amount of 2S3230 Lubricant on the seal lip and install it in the pump housing with tool group (A). Install seal with the lip toward the bearing assembly. 4. Install tool (B) on the impeller shaft and then put the shaft and bearing assembly in position in the pump housing. 5. Install tool (C) on the bearing assembly. 6. Install a suitable driver from tool group (A) and then with the press push shaft and bearing assembly into the housing. Make an inspection of the seal at impeller end of pump to see if the lip of the seal was pushed out or damaged. If so, make a replacement of the seal and do Steps 3 through 6 again. 7. Install spacer (4) in the water pump housing. 8. Install snap ring (5) with tool (D). 9. Remove tool (B) from the water pump housing. 10. Put a small amount of clean oil on the seal and install it in the housing with tool (C) and a suitable driver from tool group (A). Install the seal with the lip toward the bearing assembly. 11. Install spacer (7) in the pump housing. Install pump adapter (6) on the impeller shaft. 12. Put 9S3263 Thread Lock on the threads of the nut and then install the nut on the impeller shaft.13. Put the pump housing in a soft-jawed vise and use a wrench to hold the impeller shaft while the nut is tightened to a torque of 125 11 lb.ft. (170 15 N m). 14. Put water seal (8) in position on the impeller shaft. Put a small amount of clean oil on the seal. Install tool (E) on the seal and then push seal into housing with a press.
Do not use a hammer or similar tool to hit or drive the seal in place. This will damage the seal.
15. Install 5P7350 and 5P7352 Spacers (11) on the pump housing. Put impeller (10) in position on the shaft. Use the 5P7353 Spacer (9) and a press to push impeller (10) on the shaft until spacers (11) can just be removed between the pump housing and impeller. The 5P7350, 5P7352 and 5P7353 Spacers are all part of tool group (F). The back face of the impeller is used to locate the correct position of the impeller on the shaft. The impeller must not be used again. Make a replacement.16. Install water pump on engine front cover. Make sure vane clearance-to-front housing is .011 in. to .033 in. (0.28 to 0.84 mm).
