I installed this thermostat in my Land Rover LR2 and after drive few miles, the thermostat broke up and caused engine overheat.
I contacted the supplier and they sent me the thermostat again.
After reinstall the second thermostat, my wife was driving the LR2 and again the thermostat broke up causing engine overheat again.
I finally bought the original part, but now I have antifreeze leaking in the engine due to overheating. Now I have to change the engine head gaskets or replace the engine.
