Water Temp Sending Unit Adapter for BMW V8 engine swaps

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.
