Heat Exchanger Hose Blanking Plugs — BMW M47N2 / M57N2 / N47 / N57 Diesel | E46 / E90 / E60 / E61 / E83
Seal the Heat Exchanger Hoses on Your BMW Diesel After Heat Exchanger Removal — Complete Plug Set.
When the heat exchanger is removed from BMW diesel engines (M47N2, M57N2, N47, N57), the coolant hose ports must be sealed to prevent coolant leaks and keep the cooling system intact. This plug set provides the correct blanking plugs to seal both hose ports cleanly and permanently.
Why Plug the Heat Exchanger Hoses
- Clean Removal: Sealing the ports prevents coolant loss and keeps the engine bay clean.
- EGR/Heat Exchanger Deletes: Required when removing the heat exchanger as part of an EGR delete or cooling system simplification.
Vehicle Compatibility
