Something happened in the engine causing pressure, which caused the thermostat housing to blow off, they refused to pay for that which cost me $640 then they test and say engine is bad, So they want me to pay another 2k to tear the engine down and see what part failed, I am sure if I authorize the other 2 k they will still find a reason not to pay. I am talking with attorneys now. User's recommendation: do not buy from them.
