What can be done about a faulty car repair?

I paid for a repair (replacement) of a motor. Before I purchased the motor the owner and mechanic viewed the motor and said it was the correct motor. The seller provided me with a warranty. After the motor was placed into the car the owner/mechanic said it was the wrong motor. The seller is willing to replace the motor but now the repair shop is requesting a second labor cost to correct the problem. What can be done?

Why most of the people give chance to other? why you not do collect some idea about automotive before purchased motor? Online you get more sites about automotive. they give online training also, If you have some problem you direct call and contact with them.

Your problems seem uncommon and natural. If any other person say that motor is okay then case would be different. But whether a mechanic said that motor eight before work and change statement after work as wrong and demand charges for repair my suggestion is change the auto repair shop as you have to pay labor bill. And you may take suggestions from mechanics by online as tiremania.net
