If it has done a lot of short journeys - it may be built up condensation.

If it is chucking out a lot of water and steam even when hot, the only place that can come from is the coolant system, meaning the head gasket is probably fked.

Sometimes you will get other signs like a mayolike substance under the filler cap, but when my head gasket went on my other car years ago, I didnt have any signs righht up until the day it blew spectacularly on the A303 hehe

Other thing to check for is signs of oil in the coolant header, but again, these things may not show up.
