Since this car is new to you I have a general rule when it comes to anything coolant system related:
Don't guess. Have the professional check everything out. You can't kid around with this part of the car.
The cap is cheap but plays a critical role. In my opinion, the latest cap should be part of the PPI, as well as replacing the coolant tank. Coolant should be flushed at some interval, people debate how often, but once you decide to do this you have to make sure it's been done right by previous owners.
