Well, my custom C&R radiator arrived today.  Looks like nice workmanship. Getting ready to connect all of my cooling connections. I ordered the -16 hose and fittings today....I ended up using Summitt, as I had a credit there, and they had everything in stock, and I want to make some NOISE !!!   Unfortunately, I ordered before finding out about Pegasus....That's OK....at least it's on it's way.
      I purchased an aluminum expansion tank from Canton Racing Products, part number 80-200  see www.cantonracingproducts.com/tanks/expansion_tanks.html   It has a 1/2"NPT fitting on the bottom, and a 3/8"NPT on the side, and provisions for a radiator cap on top.
     OK....I know the two -16 AN fittings on the radiator will go to the top and bottom large inlet/outlets on the waterpump.  That's when the water gets muddy....where might I make the connections for the expansion tank so that I can put water into this thing?  I need to furnish a little more information.  I am also planning on installing a heater core/fan combination in the cockpit for heat.  I found that there is a 5/8" barbed heater core nipple underneath the oil filter.  I had originally figured on using that to go to the heater core. There is another area for a fitting on the water pump. It is an angled fitting right next to the very bottom of the water pump where the large -16 hose will connect. See area labeled "connection 2" on the picture of the water pump. I had planned on using that for the other connection to the heater core. Finally, there is also another plug on the water pump labeled "connection 1" in the same picture. I have no idea what that is/was for.  Any suggestions on how to incorporate a heater core and this expansion tank into my system?  I planned on installing the expansion tank at the very top of the firewall, above the engine.  Any and all suggestions are welcome and very much appreciated.  Sorry for all the questions....I would much rather learn from "those that have gone before" than to make my own expensive and time-consuming mistakes.  Maybe I'll do it right the first time?   Thanks again for all of your assistance.  Paul Conner
