Still doesn't explain the coolant light though. Any ideas????
    There is a flow restrictor on the heater core line and it reducess the volume of coolant that will travel through the heater core. Due to the great invention of dexcool, now you end up with clogs. The flow restrictor, crossover pipe on the back of the heads, and the heater core clog up all the time. I took my heater core out and flushed it. tons of crap came out. I also flushed the line with the flow restrictor and crap came out as well. When I did my engine build the crossover pipe was clogged up as well. after the heater core and restrictor flush the heat worked again, and after the crossover pipe was cleaned out the thing was a breaze to bleed the cooling system.
