Drain coolant. Remove fan and viscous, cover the radiator matrix with cardboard to protect. remove the drive pulley, some have two taper head set screws to locate pulley, remove these they can be a fiddle due to the closeness of rad.   Remove pump and use a puller to remove impeller  Remove the bearing shaft locating set screw and press out assembly from housing.  press out and remove drive flange.  Clean pump housing and pump casing on engine. Reassemble but first do check for run out on the bearing shaft counter face. One kit I had was u/s faulty.  Tip, take time to line up bearing hole with the housing locating hole.  Press the drive flange to shaft of bearing assembly Fit bearing to housing and fit locating screw. Fit seal assembly and then press the pump impeller on giving a working clearance of about 45- 50 thou. Use the shaft when pressing the impeller not the housing! | ||

Patrick L, Thanks for taking the time to document your job. When you say "fit the locating screw" do you just do it by eye? | ||

Nice instructions. Two warnings. The pump housing is VERY brittle. Do NOT lever it or tap it with a hammer etc. Make sure the impeller is a very tight got on the shaft. Good luck with her. | ||

Paul, thanks. The impeller must be removed with the puller as you state no levers they are a no go. Use the threads in the impeller to locate the puller.  Worth mentioning is the drive flange that takes the pulley and viscous fan assembly, it is important that there is a good interference fit on the pump shaft, it is all that locates it, it must have much more load pressure than the impeller any doubt use some bearing locktite. BTW the faulty counterface came already pressed to the shaft so I never checked for run out that was 14+ thou! After refitting and before fitting the top hose make sure the rad tubes are ok after reverse flushing the rad that I carried out previously. Pix through top hose rad inlet.  | ||

Ross, 90 degrees off top bearing face centre line through both holes. Good eye sight is a bonus. |
