Seal kit instructions are incomplete to say the least. Must make four different presses.
1) Press bearing/shaft assembly into pump housing. Using appropriate socket on outer race, press from the front until bearing is flush with front of housing. Impeller end of shaft will be almost to plane of back surface of housing.
2) Press pulley onto front of shaft. Support impeller end of shaft while pressing. Press until front of pulley is .5" behind end of shaft. (I pressed it on a little more than this and the pulley rubbed on the housing, causing me to have to use a puller to move the pulley forward.)
3) Press seal assembly onto impeller end of shaft using supplied tool, which presses the rotating end of seal onto shaft and then simultaneously the stationary part of seal into the housing. The instructions say the tool "sets the preload on seal faces", however see next step.
4) Press impeller onto shaft. Press until back of blades are flush with back of pump housing. At this point the back end of the shaft will be approximately .1" recessed in the impeller. It is not possible to see if the front face of the impeller contacts the seal assembly, perhaps pressing it slightly further forward and increasing the spring load. To determine this, I should have measured the length of shaft behind the seal after step 3, and the length of the impeller.
When removing/installing the radiator, it makes things much easier if unbolt the thermostat housing from the engine. This allows the plastic shroud to be moved to the rear to clear the radiator as it is raised/lowered. Not having a replacement gasket, I used grey RTV when replacing the thermostat housing.
