David,
I don't have a water pump here at home, but I went out and measured the old
hose that I had on there before changing the cooling system, and it is
1-1/2" I.D..

Bill, thanks, that's exactly what I was looking for. I lay in bed last
night thinking about hole saws & fly cutters and knew there was another tool
I was not thinking of using. The Unibit is the perfect thing - I have the
3/4" big one. Thanks.
As I re-measured my cores this morning, looks like, if I leave 1/8 clearance
from inbd and outbd edges of end cap plate, the new/desired hole could be a
max of 1.0 inch. I think 3/4 is what I'm going to stick with to replace the
existing 1/2" OD tube.
Ed, Steve, anybody: What size water hose (ID) is standard on a 13B water
pump? I need to know what size "inlet/outlet with bung" to buy to weld into
my "parallel flow 'splitters' to accept a water hose of same ID as Mazda
RX-7 o 8. I googled "bung radiator" and got www.becool.com which has a
".080 1 1/2" X 6" long straight universal aluminum inlet/outlet with 3/8"
Bung". Local Mazda has no hoses, radiators, or water pumps for me to
measure. Anyone know the ID?

I used a "Unibit" step drill to open up for the tube to be welded in, you
can start small, and increase a 1/16" at a time checking for clearance.
Each core may be slightly different, so you should proceed carefully and
measure more than once.
