i had my car fixed at a repair shop spent $1500 in the past two weeks there I picked up car Fri. afternoon drove less the 20 miles and the car starts smoking and engine blows. when I left the shop on Friday I noticed the car smoking I asked the repair man he said it was going to smoke because of the thing they had fixed it was burning off the sludge. so at first I didn't pay attention to the smoke. but it was smoking alot then I decovered that it was the radiator hose that the guy said he was going to replace it but he had to order it. now he says it a blowen head gasget and will cost me another $2000. is he not liable for the damage to my car?
