HEATER BLOWS COLD

2000 Dodge Durango

Heater problem
2000 Dodge Durango V8 Two Wheel Drive Automatic 150000 miles

The truck overheated on me the other day, I dicovered the thermostat was bad (boiled it and it didn't open) and I also replaced the top radiator hose. The water pump is a year and a couple months old. Now the heater blows cold and the engine still heats up past the 210 mark on the guage. The top radiator hose does not get hot, but I took the new thermostat back out and heated it untill it opens seems to be about 190 deg. Any suggestions?

Any visible steam near the heads? Or white smoke out the tailpipe? If so get a block test kit, they run about 50.00, this will check for a cracked head or blown head gasket. Also make sure the tstat is in right, the copper spring should point to block!
