SBC to LS Swap Coolant T emperature Sensor Adapte

The SBC to LS Swap Coolant Temperature Sensor Adapter by ICT BILLET is an essential component for engine builders and hot rodders undertaking small-block Chevy (SBC) to LS platform conversions. This adapter addresses the critical challenge of integrating the cooling system plumbing from an SBC configuration to the coolant temperature sensor requirements of a modern LS engine.

Constructed from lightweight billet aluminum and finished in natural anodize, this straight-thread adapter features a 1/2-inch NPT female port on one end and a 12 mm x 1.50 male thread on the opposite end. The dual-thread configuration allows for seamless connections between SAE-standard NPT cooling lines and metric LS sensor bosses, effectively eliminating leak points and simplifying wiring harness integration.

This adapter is particularly beneficial for builders converting carbureted or fuel-injected SBC engines to LS architecture, especially those retaining original coolant system designs or custom radiators. Its compact footprint fits tight engine bay layouts without requiring extensive re-plumbing, making it a practical solution for performance builds.
