When the radiator was replaced, I would assume that the cap has been replaced as well. Radiator caps that have worn out release steam from the system which means lesser water being circulated. Check if your coolant/water decreases. It may be a leak from the hoses or the engine itself. The leak from the engine may be a bad water pump or the water pump may be bad and water is not circulated correctly. Check the also the fan if it is running once the engine has warmed up. Check the fuses for the fan and its relay. Swapping relays with the AC fan to test is one way of testing if it is the relay or the fan that could be bad.

2004 impala overheating. Changed thermostat already.

Anna, thermostats don't fail all that often. If you are overheating after a new one, the problem most likely resides inside the radiator. Radiators can get plugged with gunk over time if they are not flushed at least occasionally. Have you tried that yet?

Does the overheating happen while the car is moving or only when at idle for a period of time?

Is the coolant less than two years old? If it is more, I recommend replacing it after doing a cooling system flush.

If you still experience overheating after that, I recommend having a good radiator shop give it a look.

Good luck.

If you already put in a new thermostat, then the radiator must be clogged up internally and needs replaced. Maybe the new thermostat is defective.

Overheating real fast and I have already replaced the radiator

If your car is overheating extremely fast - the first thing to check is that your thermostat is opening. If it doesn't open then the car will overheat very quickly. When the thermostat opens water will be able to circulate through the radiator, and be cooled.

You might try replacing your radiator cap or if you system is pressurized, you may have to replace the degas bag (fill container). Another problem could be a bad thermostat or an improperly installed thermostat. I forgot to mention, does your engine fan operate? If not, that would also cause your car to overheat.

My volkswagon jetta 2.0 from the year 2002 is overheating and it blew up a few pipes i already replaced, but it still over heats i wish to know how can i fix the problem, and what might be the problem?...

Are your fans working? If they're not it will cause overheating while stationary or in slow traffic. Overheating while driving points to the radiator.
Get some engine flush into the cooling system and run the car for a couple miles. Then let it cool down and remove all the water(Take both large hoses off the radiator). Then stick a hosepipe into the radiator and let the water run until clear.
If this doesnt work remove the radiator and have it reconditioned/replaced. Removing the thermostat will not cause the engine to overheat. It just causes the engine to take longer to reach operating temp.

2.3l ranger keeps overheating, been through two radiators already.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

the drain plug is on the bottom of the radiator,simply follow top radiator hose to the engine at the end should be your thermostat which is definitely causing the over heating
