If it has play in the water pump I would be scared to drive it. I've had mine go out twice, about every dozen years, the first time I slowing coming into a small town and suddenly the truck started shaking violently, I thought I had blown a front tire, it was the water pump! the bearings went and it had massive play in it and it had not even been leaking. I was so lucky because I looked across the street from where I had pulled over and there was a napa store, they had one in stock. Be super careful when removing the fan!! I bumped the fan on the radiator, and put a tiny hole in it, could not believe how easy it happened. Turned a 4 hour roadside repair into an all day adventure. The second time I lost it, it looked just like yours, leaking down the front. Good luck
