Anna-- The Speedy Racers need to make sure that they cool their engines so they don't get too hot while racing. Put cool water into your radiator to keep you engine cool. Do not put sugary drinks or sodas into your radiator. Also keep the sugar, salt and fat out of the fuel you are putting in your fuel tank. This will keep your motor running.
