The core I have is just like 'Big Mamma', not the copper tube style (which I was trying to find)...I just got too itchy and tried to throw the thing together myself...against the advice of my friend's dad, who does appliance repairs/service (including air conditioners and refrigerator/freezers)
He says that high side pressures are in the 100psi range...a far cry from what a typical heater core sees...heat...engine coolant gets into the 220-250ish F / 100-120C range (if someone tells me the boiling point of water, I'm gonna kick them in the nuts)...
Actually, I got the core from Canadian Tire (Canadian eh?), but I cut off the ends of the tubes, and soldered pipe fittings on, then off, then another set of fittings on to reduce to the small copper tube from my compressor...I think I may have voided the warranty...:shrug:
I don't really want to spend too much money on this, since it is really only gonna get used for about 60 minutes...then I'll get sick of the hassle and go back to my 8045...I just 'happened' to have most of the parts lying around...
