My daughter took her car to Clarks and they charged her 600.00. I asked him if the car was worth 600 dollars and if it would run after that and the owner said yes. Her engine blew 3 days later. When I called they said "I told you I would get it running you didn't ask me about the engine". WOW what a rip off, so if someone comes to your job, you are not supposed to lend your expertise to help them make the best decision. UNACCEPTABLE. Do not ever go to Clarks Radiator on 11th St. in Rockford, IL
