meatish tape helmet

Newly acquired GXL in my garage, ran fine til yesterday. Now it emits smoke and smells of coolant after about 5 mins of running. I havent identified the source of the steam/smoke yet, but it's coming from the left of the engine, to the left of and under the air pump. The hoses all check out, and there are no parts which are visibly broken. Anyone out there who can diagnose this problem?

Lower rad hose or water pump probably has a leak.
