Question about 2002 Ford Ranger Regular Cab
The heater does work , ithought it was heater core,we have done all we know
Are the heater core hoses hot? If so then you will need to replace the air temperature control blend door and its electric actuator. If this is the problem you can speed the repair time (10 hours) by using a kit called a Heaterbeater. You can buy the kits on eBay.

SOURCE: engine overheating
No water pump issues I am aware off, are you sure you bled the air out of the cooling system? If not fill the overflow bottle all the way full, then use a floor jack and raise the front of the car as high as you can ( this allows air to go to top of radiator tank), then run the engine at high idle speed until the cooling fan ( I assume the fan works OK?) comes on, but avoid letting the engine get into the overheat area of the guage, if it does turn it off, run water over the radiator until it cools, check the tank and radiator, top off if you need to and repeat above procedure, if this doesn't work you have some other problem like no or little flow in radiator.

hi from uk when engine temp is hot and heat set on max openhood and physically feel both heater hoses for temps ? if one is hot/warm and other cool ? then coolant is not circulating thro the heater matrix(radiator) as you have renewed most parts suspect without success? may i suggest your actual circulation thro the matrix is most likely to be the heater coolant valve which is elec operated as you turn the heat selector in dash both heater hoses connect to this for open/close to matrix of coolant so if valve is failed it is not servicable ? and not to difficult to locate if you follow h/hoses to heater ensure there is power to the actual valve b4 you consider replacing valve easy diy and not too expensive ? hope this helps you ?

you have an air lock in cooling system try bleeding it if it still does it could be exhaust gases in cooling system caused by a leaking head gasket have it checked at garage who have a chemical tester or sniff tester
