I cant see that much cooling going on when you just crossed a creek or small lake. I would think the pressure would still be there and aid the seals. Now if it was real hot and you went swimming for the day I could see the cooling thing maybe. For every foot of water we go there is and increase of pressure in fresh water of 0.432.
You will get water in there especially if you get stuck in it. Ask me how I know, luckily it was only the steer axle so I only had to change out the fluid in that axle.
