2003 Chevrolet Tracker overheats on inclines. New radiator, new water pump, new thermostat (x4). On recent trip, thermostat removed and worked fine. Is this advisable. Two dealers and two outside mechanics unable to fix. Thanks!

Update: Third independent mechanic thought is was the water pump housing. No. The coolant isn't circulating. The coolant coming from the engine to the radiator=hot. Coolant coming from the radiator back to the engine doesn't seem to be working. The hose is too cool to the touch and can't tell if liquid is coming through at all.
