Bargain Mini- Water Pump Replacement
I removed the supercharger and water pump for supercharger service as one unit, that is not removing the water pump separately.
I put the water pump back onto the supercharger but now I'm wondering, should I install the supercharger first, then install the water pump? It looks like it might be easier to manipulate everything installing as 2 separate units.
I had a little delay as I received the wrong knock sensor but the correct part is in and I'll be starting to reassemble tonight.
Thanks,
rob

As I recall, I bolted them together prior to reinstallation. Secret is to leave the bolts on the coolant flange loose so that you can wiggle it slightly while repositioning the combined supercharger water pump assembly. Then once the SC/WP is bolted to the block you can snug up the coolant flange bolts.

Looks like they put it back on together

I tried bolting the S.C. and the water pump up separately [before torquing everything] and it was definitely a no go.
They have to go on as a unit and there's just enough room to tighten the two [2] 6mm that hold the water pipe inlet to the block. You do need to torque the water pump to S.C. bolts first as you can get to 2 of them but not the third, [at least not with my torque wrench].
As JAB suggested the water pipe bolts were left just loose enough that it could move a little and the pump slipped right in. The small hose I had attached on one end, [toward the metal pipe] and used a tiny bit of dish detergent on the other end and that slipped right in at the same time.
Don't forget to put the clamp on the hose fro the pump end before installing everything. It's much easier to do both at once as opposed to putting the small hose on later.
All in all it went on quite smoothly.
So now, one less thing. It's nice to be putting things together as opposed to taking them apart.
