During the colder months the structural integrity of your trusty old tank could suffer. Worst case scenario: HULL BREACH. If this happens set up a containment field immediately. This will save the surrounding area from too much damage should you have to jettison your core. If you're lucky enough to avoid that, take all non essential systems off line and run a level 3 diagnostic. If you've got a newer unit you'll probably want to check the phase inverters and plasma coils. Regardless, do a baryon sweep -- just to be safe.
You'll be up and running in no time!
