Radiator Hose Problems of Chevrolet Blazer

Purchased 1996 chevy Blazer 1/15/04 from carmax. Experienced frequent issues with heating and cooling. 3/22/05 1st mechanic found no trouble for 2 days, then determined thermostat was bad. 2nd mechanic replaced thermostat. Broke down twice due to pressure in cooling system forcing radiator hoses off. 6/4/05 mechanic reseated hoses & clamps, replaced radiator cap, and flushed system. 25 miles away from shop temp shot up to 260 degrees and blew all fluid out. Tried refilling and water is rushing out of the radiator end caps as fast as we're filling it. There's an extremely high level of sludge that appears to be dex-cool related in the overflow tank and has also been seen in the fluids that have been draining during breakdowns.
