Some engine swaps and racing applications do not need the heater, but it is tough to block off with the 7.3-liter Godzilla engine. The factory rear hose port is retained with a bolt (and the port is not tapped), and the front port is a tube with a hose barb that isn't removable. This kit includes a billet plug with an o-ring seal retained by a bracket and bolt, and the second plug is a rubber cap with a billet cover that clamps over the tube. These caps and plugs provide a more attractive appearance than other options.
Features:
  • Elimination of the heater is difficult on the 7.3-liter Godzilla engine since the hose inlet and outlet passages are tough to plug & look cobbled up using traditional hoses, clamps, and plugs
  • Machined steel billet plug with o-ring seal, mounting bracket, and retaining bolt – blocks off the rear port
  • Special rubber cap with clamp-on aluminum billet cover – blocks off the front port
  • Plug and caps designed to handle high pressure & high temperature – typical conditions of the cooling system
  • Easy Installation without the need to tap holes or fabricate special plugs and caps
  • Steel plug features a clear zinc plated finish, and the billet aluminum cap is black anodized – for a more attractive finished look (than other options)
  • Ideal for use in engine swaps or racing applications that do not require a heater
Note: The 7.3L engine design does not require a loop between the heater outlet and inlet. It is safe to block both ports off.
