I don't have the info at hand but to what degree does coolant raise the boiling point? I am trying to dig into the memory banks to remember automotive cooling systems 101 and the effect of the radiator cap in raising the boiling point. This is called the pressure cooker principle, where temps of 100d Celcius+ are achieved by raising the pressure within the cooker. So yes a hot motor 100+ will have more pressure in the system than a motor at 85d C but if it is enough to cause damage is hard to tell. However given the fact that the radiator cap did not blow (unless it is the wrong one) is a indicator that no damage was done but it is a 20 year old motor and just that little bit of extra pressure could perhaps maybe in some circumstances done something which may cause problems further down the road but personally I would just keep going. However we are all just guessing and no one can give you a definite answer in regards to damage done. It's like asking how a auto box will last once it starts flaring in the shifts, my Mum's lasted years and is only now starting to die properly. Sure we could have fixed it when the first signs of trouble started but we didn't.
