water pump replacement extra parts

not another how-to: car in question is a 2001 93 2.0 turbo. surely thousands have been replaced since then.

the pump replacement is a new not rebuilt 1/2 pump. the backside is reused. on my model saab, you have to remove entire pump, then take the #30 torx screws out for 1/2 pump replacement. hope that made sense.

IMO extras necessary to (once and for all) complete the job: note: sizes of bolts for tools listed in ( ) from memory for reference.

-if your replacement pump does not come with a gasket you will need to get or make one.
-if your replacement pump does not come with O-rings you will need to get 2 of then. one appears thicker than the other. both about 1-1/8th inch or so

if just draining for water pump replacement. if flushing fully consult manual or someone else.
-1 gallon antifreeze of choice (not going to get into choice specifics, other than to suggest that most euro cars do not use silicate "sand" type). sizes of bolts for tools listed in ( ) from memory for reference.
-3/4 gallon of distilled water.

-large dimension drain pan (i used a shallow plastic aprrox. 2 feet by 4 feet). if you don't you will know why i metion this.
-power steering pump metal line O-ring approx. 3/8ths inch. (16mm nut size).
-about a 1/2 pint of power steering fluid
-turbo inlet tube O-ring approx. 2 inch diameter (with #30 torx clamp is removed using two at 6 inch ratchet extensions).
-turbo inlet tube secondary metal tube (with 10mm bolt) . stock one is thick, and a pretty green color.
-water pump upper hose
-water pump lower hose
-water pump U-shaped bypass hose
-thermostat (use stock, not going to get into it here).
-maybe some spring clamps for hoses if yours are not springy or rusted. radiator has plastic spigots, be careful if deciding on cheap hose clamps.
-blue (medium strength threadlock) for A/C bolts!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (clean bolts of grease with brake cleaner first).
-note: (13mm) mounting bolts on P/S pump.
-note: (12mm) banjo bolt

----aside:
-if your A/C compressor was changed out, make sure the red wire has enough slack in it before you unbolt the compressor.
-metal turbo clamp is delicate and bends easily. this is not an opportunity to show how strong you are.
-make sure that your indy saab garage is not closed on a saturday, when you break your turbo intake clamp.
-i don't and won't reuse O-rings
-A/C pump will not drop down after bolts are removed because it is hanging on a 'hook', lift it up to get it to come down.
-inspect other pulleys for bearing wear.
-a 6 inch long phillips screw driver is the key to aligning the power steer pump mounting bolt holes. thread it through the holes from the motor (not belt side), then slowly withdraw it while threading in the top, (belt side) side bolt first.

devote about 4 hours for this.

hope it helps.
