My celica has a new radiator and thurmostat. it over heats and boils the antifreeze even after a few min of light driving. i dont understand why!!! water pumps new too.
First, anytime a thermostat is overheated, it's ruined.
Second, if this car has electric fans, are they running when they are supposed to? If not, replace the fan control module, and/or test/replace the fan motors.
When the radiator was replaced, were you certain to purge the radiator and engine of all air before replacing the radiator cap? When you refill an emptied system, you always start the engine and watch the fill level in the radiator, refilling as necessary until you know the thermostat has opened. You need to have the heatrer controls set to full hot as well. Once the radiator is filled, put the cap in place, and fill the reservoir to the level indicated for a hot engine.
Finally, check to make sure the lower radiator hose is not collapsing while driving. While this is difficult to check (because your going down the road), just replace it when you replace the thermostat.
All of this assumes you do not have a cracked head or blown head gasket.
However, regardless of wether or not the fan(s) are working - the car should not overheat unless all you have is electric fans, which is very possible. If this is the case, see about having the fan replaced; if not, the only other thing that will cause the car to overheat is the heater core. There is no real way to know if this is plugged (which causes the overheating, no flow) - accept to remove and replace it. If you have replaced both water pump and thermostat, consider this; however, before you do this, I suggest pulling the thermostat and make sure that you have installed it correctly. This is a common mistake, and can be done by anyone - When installing the thermostat, make that the spring is facing downward into the block and the needle point is on the top. If this is not installed correctly, it will most definitely cause your engine to overheat. Also, once this is fixed (if needed) let engine idle keeping an eye on the water pump (area) for leaks, as well as your temp gauge to make sure the car is not getting too hot - you will not always see "steam" when a car overheats...as water will travel the path of least resistance, and it may take a while for it to find it's way to that point - which in most cases, unfortunately is the water pump gasket - it's the weakes link. If you have any questions, please let me know - I assure you I have dealt with many overheating vehicles and 99% of the time it has either been the thermostat, bad hose, or the waterpump. Again, please let me know if you need further assistance.

Can you have a blown head gasket on this car if
1) compression on all cylinders are the same
2) no water in the oil
3) no white smoke out of the exhaust
If it is at the very earliest stages yes...however if you have a blown head gasket - you will know. replacing the thermostat, gasket, water pump, gasket...and the heater core is good (will have heat). Then you are sure to be in good shape. If you are overheating, and have not done so, simply replace the thermostat - as in most overheating cases it is this, or the waterpump. If the water pump is bad, in these cases, (most) you will have a leak from the gasket, or on some newer (aftermarket) pumps there is a bleeder hole on the top for the water (pressure) to escape. Look for leaks in the area of the water pump - engine idling...if so, shut off engine immediately and replace the pump. Also make sure you check both top and bottom radiator hoses for holes, swelling (bubble, expanded (weak) areas). Please let me know if you need further assistance.

Have the coolant system pressure tested, you may have a head gasket issue.
If everthing has been replaced as you discribed then you have a blown headgasket,it's the only thing left.
