Help! Leaking coolant

[jsbihn]

Ok, the newest piece to the puzzle so far is it seems I can drive around all day long without any sign of leaking .... as long as I dont shut the truck off ... as long as the system is running basically the truck doesnt leak.

As soon as I shut her down, then I get that drip drip drip going on
Again still no lights on the dash, still no temp on the gauges over 190-200ish, given I still havent had a chance to spray down the underneath from the overflow from the other day (but come on, its been almost 5 days now and theres been 1 good rain storm and alot of 95+ days too - it shouldnt be dripping this bad from that over flow)

Any ideas?
