I have a 94 toyota camry and its been getting hot lately I've replaced the fan sensor in the bottom of the radiator and changed my thermostat and changed my coolant. If anyone has any ideas please help me

It may be time to replace the radiator, due to phosphate scale:

Only use Toyota-approved coolant.

If you've had the timing belt replaced, did the water pump get replaced as well?
Also, check for coolant flow through the heater core (do both hoses get fully heated?).

Are the fans coming on when the temp gets up there?
