Kudos for replacing the ENTIRE cooling system, I've been preaching that for years...and for going the Zionsville route. I mentioned this on another thread, but I plan on doing the same thing with my 7 when I FI it. I've already done an electric fan conversion, but that all aluminum radiator and shroud are just damn sexy looking in there!
Funny you say that, I fixed a car for a customers, GF's, daughers car (did I say that right?) and she had been driving this car around with no coolant for god only knows how long. They told me they just drove it till it'd get warm and the car would eventually shut itself off...I was like WTF?!?! Put in some tap water (I know, no no) to see if the waterpump was functioning (nastiest brown mud came out when I revved the engine, I could only shake my head no), drained and filled the water with tap again, ran some cooling system cleaner, replaced thermostat and radiator cap, drain and fill with coolant and distilled water...car finally ran like a champ, no shut downs like they had experienced, A/C blew ice cold while I drove it around for about an hour or so. I only charged them $100, thankfully it wasn't a headgasket. How hard is it to add water?! I'm still beside myself sometimes when I see people driving around with HUGE problems like this, ignoring it as if it's going to go away if they never address it.
K, stepping down from soapbox now
