Answer Your problem could be a blown fuse.It could be a bad sensor.It could be low on freon for the air cond.It could also be a bad fan motor.All these are simple to check with a good repair manual,such as Haynes or Chiltons.Good Luck
You may have accidentally unplugged/damaged the engine coolant temp sensor while changing the t-stat.
It probley has an AIR pocket in the cooling system. Bleed the air out of the system and make sure it is full of fluid.
Low coolant? system "airbound"? Hoses collapsing under pressure clutch or cooling fan not working? Defective radiator cap?
Yes, a thermostat opens and closes in response to the temperature in the cooling system under normal conditions. If it is sticking it can cause fluctuations in the radiator coolant temperature.
clog in radiator. drain radiator by removing cap on bottom remove cap on top fill top with water see if drains out bottom. or possibly an air pocket trapped in cooling system. make sure to bleed the air from the system.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
first , the thermostat could be stuck. try replacing it. if your radiator OS losing coolant, there may be a leak in the radiator causing it to overheat, or the water pump could be bad. thermostat is the likely cause if it is not losing water.
radiator hose needs replacing. use and heat will cause hose to collapse when worn out

Low coolant Bad radiator cap Dirty or plugged radiator Thermostat cooling fan not working Water pump Collapsing hoses
The Thermostat opening & Closing, The cooling fans cycling on and off, the engine working harder than the cooling system can handle. an air bubble in the cooling system, to mention a few
A thermostat that was stuck then suddenly became unstuck might do that. If the coolant level and the rest of the cooling system seem OK, try replacing the thermostat.
Hard water, and calcium can build up insite the hoses and get released in chungs during the flush process. These pieces can get caught in the thermostat and cause it to fail. You can try removing the thermostat or just replace it as it is an in-expensive part. You might consider re-flushing the radiator as more calcium might hit the thermostat after replacing it.
