TSB 96 recomended that checking coolant level no longer be performed by removing pressure cap from swirl tank. Damages cap seal.
Instead check for half full in the expansion tank (overflow). to ease access, cut a hole in right engine cover . thus raising the tank would aid in checking level.
For application, IF the taller tank remains as the expansion overflow tank, its relative height with respect to swril doesent matter.
HOWEVER, if coolant system is converted to continous venting, making taller tank the pressure tank, then the elevation becomes importaint as to establish the air volume needed to allow for expansion
