Answer 1

Hi there,

Usually it's an air pocket in the system that will cause the code once the work has been done. If you don't have any heat at idle, then you have air in the system and the cooling system needs to be bled properly.To do this you need special equipment and to get the front of the car at least 22 inches off the ground.
