The fans are working , the check engine light came on a couple days before it ran hot,
Are your electric radiator fans working?
Hi.
This issue sounds very much to me like a head gasket checking out.

Sorry to have been the bearer of bad news.
I hope I'm wrong on this one.

Experience has proved that flushing a radiator is a waste of effort
the flush only cleans out the open tubes and not the blocked ones and the salts in the block now flow into the radiator and block the rest
check the fan operation
viscous fan hub --replace the fan hub
electric fans check the system from the coolant sensor , fuses (2) , relay and fans

Sounds like Clutch in your fan
The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.
Hope this helps!

your air damper or diverter may not be working.this is basically a mechanism that opens a flap by your heater core to control the amount of hot air that comes out.There is a rod that this flapper pivots on and if this rod is broken or the motor that operates it is not working you will either have heat all the time or no heat at all depending on which position it broke at.I know because my torrent has the same problem.To fix my problem they have to remove the dashboard to access the heater core which amounts to major $$$. I hope your problem is an easier fix. good luck

Sounds like you have an air;lock in your cooling system.Try placing a bleeder on the return hose to the heater core ........looks like a small tap
disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec
