Check for low coolant, the cooling fan clutch could be faulty it is free wheeling all the time, when engine is hot fan clutch should have some resistance when you turn it by hand. if all is good, your ignition timing could be off,your radiator and engine need flushing out,you could have faulty water pump, a bad egr valve will cause engine over heat if stuck closed which will engine combustion temperature get hotter.make sure you have 50 / 50 antifreeze and water in coolant system too much water in coolant system will cause engine over heat.also radiator pressure cap.check all those things i told you see what happens.

some thing is wrong , you must have a cloged cooling system, check your radiator make sure it circulates , and if water pumb is new then the only thing left to do is flush the readiator good, i am assuming that your engine still ok no head issues, do you loose any antifreeze , do you have any smoke from the tail pipe, if your answer is know , then you must flush your radiator to fix your heating and heater issue.

About the only thing that you didn't list is the cooling fan. Are you sure that it's working properly? Drive the car until the engine starts to get hot. After awhile you should hear the cooling fan come on. After you have driven the car for a while, park it and open up the hood. If the upper radiator hose is almost too hot to touch, then check to see if the coolant fan is running. If it isn't, then turn the AC switch to "AC MAX". If the fan still doesn't come on, then a malfunction is indicated. Try to locate the fan control relay and swap it with another relay that has the same part number. Use a relay that will allow the engine to run. Allow the engine to reach operating temperature and see if the fan comes on after switching the AC switch to "AC MAX". If the fan now operates, then replace the relay. I hope this is helpful to you. Thank you for trying Fixya.com.
