Brendan and I.B. Thanks for the info.
I'm really hoping that everything made it through the ordeal ok. I tend to overthink/worry about these types of issues, but just want to make sure.
I'm not really sure of the current status of the radiator or fluid levels. Hoses all seemed to be okay. There was some antifreeze residue blown across the valve cover, but I'm assuming (until I have a better chance to look it over) that it was from the radiator boiling over.
You mentioned 225 as being a boiling point for a 50/50 mix. According to my gauge, it was at least there.
Internal damage and/or head gasket is my main concern at this point. Hoses and such are quick/cheap fixes in comparison.
The changing the oil is a good idea, and cheap insurance.
I'll try and get it all checked out this weekend and report back on my findings.
Keep your fingers crossed.
