Awesome, thanks for all the info guys! I did buy a new cap when the rad got replaced, so that should be good. And for stuff I can do immediately, there does not appear to be oil in the bottle, just green, green coolant.

I will check the hoses and the radiator a little more closely on my day off. Also it has not overheated since I have owned it and afaik it hasn't been overheated by the POs.
