GMC S15 Coolant Problem
When I bought it it a few weeks ago it was overheating, I replaced the thermostat and the water pump and it is still overheating, the fan is a thermostat controled fan and it seems to be fine and I see no problems with radiator flow. I am stumped

Besides the temp gage, any signs of overheating? Is the coolant reservoir over-flowing? You can see coolant flow through the radiator? You may need to flush the cooling system? Could be air in the system? Combustion gases in the coolant?
