The 180-5561 Junction Block is used in the 121-7727 Water Lines. This group provides coolant to the turbocharger. The 180-5561 Junction Block has been improved. Use Illustrations 1 and 2 to help identify the junction blocks. The improved junction block (1) provides increased engagement between the junction block and the supply tube (2) for the coolant. The improved junction block also limits the distance of insertion of the supply tube (2). This helps prevent cutting the O-ring seal that is on the end of the supply tube.
