If the pink is coming from the inlet manifold gasket you may not have HGF - the coolant could be escaping from the manifold gasket and evaporating on the head.. fingers crossed as those gaskets are DIY and only about £3!
sadly it is ****ing out of the join between the block and the head... the entire front side of the block all the way down to the sump is BRIGHT PINK! its pretty ****ed...
also have a crank oil leak on the drivers side... any ideas about that?
