Water Temp Sending Unit Adapter for BMW V8 engine swapsBMW-127
Using the BMW water temperature sending unit in the Chevrolet engine will make the BMW water temperature gauge read accurately.
The BMW water temperature sending unit has a 14mm x 1.5 thread. Stealth Conversions has a brass adapter (shown above) that accepts the BMW water temperature sending unit, and has a 3/8 pipe thread (NPT) that screws into the Chevrolet heads or intake manifold. If you have an older engine which has 1/2 pipe fittings, a 1/2 to 3/8 brass bushing can be obtained at most plumbing or automotive stores.
