My 2004 Camry is overheating and blows cold air
No circulation. Check thermostat. If not check water pump. This goes without saying but check anitfreeze level. It's one of those three. Don't overheat the car and drive it as it will warp your heads and cost a LOT more.
The water pump on these are hard to see leakage, unless its massive. the best thing to do is watch the youtube video on the pump removal, pull the pump and physically inspect the "weep" hole on the top behind the pulley,and the expansion plug on the bottom behind the pulley. these are the common leak points. Also, cross connect the fans and see that they both physically work, or short the two pin connector for the fan switch on the bottom of the radiator. If the fans come on then its the switch, if they dont, its the fan or no power to the harness connector. If both fans operate with out doing anything, then its, of course not the fan circuit at all. Move on to the hoses. 2 radiator hoses, Upper and lower. Check for bulging and weakness. then the 2 heater hoses. if nada, move on to the radiator. look for coolant residue along the sharp angles and cap connectors. small fractures on the flat and smooth areas. Rent the tester from your local auto parts. Pressure test the system to help find leaks under pressure without starting the car. I know your post is 2 years old, but someone else may read this and it would/might be helpful for them.
