Default Car is overheating one click over half....

engine coolant temp sensor and after run switch have been changed recently but still car overheating in heavy trafic. i have noticed that my aux fan does not turn on at all(spends freely). hopefully changing the thermoswitch cures the problem but if it doesn't what else should i be looking at.

fyi timing belt, thermostat, water pump etc were changed about 10k miles ago.

Default aux fan aka ac fan that is an electric fan also you might want to look into the acc belt

and the belt tensioner, if it is bad and it would cause the h2o pump not working 100% and it could takeout the alternator!
