Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
The fan is wired to run with the heater or the AC on, If it doesn't run alone chances are your coolant temp unit is bad, But first check all conections. The coolant temp unit in most Vehicles is located near the thermostat on the engine block.

Fan switch should be located in the upper radiator tank. Two wires to it. it works off the temp of the water.

It might have a bad tempature sensor or a stuck thermostat .Faulty relays or a wiring issue I recently found a bad cooling fan plug on a 06 pt cruiser.You should first have it checked for computer codes it may show a code for the problem.
