DAYTONA BEACH, Fla. -- Crew chief Chad Knaus was fined $2,500 by NASCAR on Tuesday for a rules violation before qualifying for the Coca-Cola 600.
Knaus, boss of Jimmie Johnson's Chevrolet, was fined for using an unapproved refrigerant near the fuel system. The team never made a qualifying attempt because the motor broke before Johnson went onto the track.
So they changed the engine and Johnson started last in Sunday's race. He went on to win it when NASCAR called it because of rain after 414 miles.
