I have taken off the water pump fan and pulley on my LC to give them a paint. I have read before in the Forum that a bloke who worked at the Holden factory advised that 2 bolts were painted black for initial painting and then later, when installed on the motor, Holden fitted 2 unpainted bolts.
I can't find the post. If this is the case, I may as well paint 2 bolts black to keep it original.
What are your thoughts?
