Not spitting fluid, fluid level is ok, temp light is on also turn off engine light is on. Fans are working, but motor is hot. I'm thinking termostat -__(installed new thermostat, prolem fixed)

It could be a thermostst. Has the cooling system been drained and refilled prior to this. They can harbor an air pocket that will cause it to run hot. When it indicates overheat, does the upper radiator hose feel hot, or can you place your hand on it? That would be an indication the thermostat is stuck closed preventing flow.
