Toyota Repair: 2003 Toyota Solora 4 clinder

Question
I replaced my cracked radiator, thermostat and flushed engine, over flow bottel and hose. I check for leaks and had none. I ran the engine for a few minutes w/ heater on high. everything seemed ok, then the engine was running hot and no heat. I the stopped engine. and recheck engine and found upper right radiator hose very hot, the lower left rad. hose only slightly warm. Same with heater hoses. It feel that no water is curculating. I tried to beed the system several more times. Could egnine be air bound or a bad water pump? Please help???

Answer
Sometimes it can take a while to get the air pockets out, with the engine cold, disconnect the upper hose from the radiator and pour coolant/water slowly into the hose opening, repeat this if necessary, I have seen water pump impellers fail but only on high mileage cars, 150,000 miles plus, if the cooling system had a lot of rust in it then the water pump is a possibility.
