OVERHEATING 95 4X4

1995 GMC Jimmy • 6 cylinder 4WD Automatic • 165,231 miles

My 95 GMC Jimmy 4x4 4.3L engine Vortec is overheating, it was leaking coolant at one time, we fixed 3 freeze plugs the engine is no longer leaking but continues to overheat the water pump has been changed, we took out thermostate, put in better raditor, there is no coolant in the oil and it's not smoking so we are thinking it's not head or head gasket not sure though. We have flushed out the overflow and raditor. It does start and will run but usually starts to over heat pretty fast. Can u please give possible problems.
