The thermostat will not open properly when installed backwards. The coolant will not flow and the engine could overheat.
leakage will happen and the seal will be worn in a short time after installation.
Possibly the new thermostat is bad...........don't laugh it can happen. I'm not sure if you could have installed it upside down. Sometimes that is possible but I am not familiar with your specific engine application.
I had that happen on '87 ford ranger. Tore it apart and found the thermostat was backwards. Also if its a "fail safe" thermostat it sticks wide open preventing overheating but also will take longer for your engine to warm up.
