Hi there - the first task is to be sure you have bled all the air out of the system after changing the thermostat and refilling the reservoir. This includes running the engine at a fast idle for 10-15 minutes, with the heater running full blast (max heat, max fan), the coolant reservoir off, until air bubbles are no longer coming out of the system (there may be other air bleed points for your vehicle to eliminate trapped air). Trapped air will cause overheating as easily as any component failure. I recommend a cooling system inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
