1. start the engine and leave the radiator cap open.
2. put a cardboard cover or a rug in the front of you radiator.
3. let it runs 20 minutes or more, see if it is overheated and see the water or coolant in the radiator circulated or not. If not, as soon as you have already changed water pump. thermostate and check the hoses, no leak, I think your radiator was blocked.
Did you put stop leak before?

Ok first check the water pump and if that is ok sounds like the head gasket blown, look for water in the oi, thisl will be like a milky colour

Its under where the top hose goes into engine, It is pretty easymake sure to get some forma gasket when putting back together

You can replace the radiator yourself, but why do you need to? The thermostat is on the engine. Follow the large hose that goes to the engine block....not the water pump. The thermostat is under that or sits on the top of the engine....looking for a pic for you!

SOURCE: car's overheating
Check to see if your radiator fans are working. If you have A/C just turn it on and both fans WILL come on unless there is a problem ie: bad fuse(s), relay(s), or motor(s). I don't mean to scare you, but, someone "could" have a pretty bad head gasket leak and still not see fluid come out of the exhaust. If the fans are both working, it could be any number of things from, a faulty coolant temp sensor, a faulty dash gauge, possible air bubble in the cooling system. Another easy check is coolant consumption, if you are leaking coolant into the cylinder while engine is running and/or into the crank case. Just check to see if your coolant level is going down and/or your oil level isn't growing because of coolant filling up your crank case. Hope this info helps...(subytech)...
