The BMC Aluminium Radiator comes with your choice of a Filler Neck for an on the radiator cap, or without. When ordered without a filler neck, a pressurized overflow tank like the 1977-1980 MGB ha, must be used. It certainly is our preference to have these include the filler neck for any model year MGB.
This system is designed specifically for the MGB V6 3.4L Conversion with the 1993-1995 Camaro/Firebird 3.4L V6. but is also commonly used with any Rear-Drive GM 2.8/3.1/3.4L V6 1982-1995.
This radiator uses the Forward Located 1977 - 1980 designed MGB panel system, but adds a Cap, Drain, hardware to fit a cooling fan on the engine side, and larger inlet/outlet pipes facing in the same direction as the factory 1.8L 4 cylinder engine.
For 1962-1976 MGBs, our radiator installation panel kit is required, and the BMC Designed Air Box fits these systems like almost they were designed by the original creators of the MGB.
The NPT Drain on the bottom tank can be used as an optional lower thermo-switch plug for engines running carburetor.
PLEASE NOTE: Photo shown has the Additional Automatic oil cooler NPT fittings. This has an additional charge to it when ordered.
