SBC to LS Swap Coolant T emperature Sensor Adapte

The SBC to LS swap coolant temperature sensor adapter by ICT BILLET is a precision-engineered fitting designed for engine builders and hot rodders performing small-block Chevy (SBC) to LS platform conversions. This adapter solves a critical integration challenge: bridging the cooling system plumbing from your original SBC configuration to the coolant temperature sensor requirements of a modern LS engine platform. Whether you're upgrading a classic muscle car, street rod, or performance build, this adapter ensures proper coolant temperature monitoring without fabricating custom solutions.

Constructed from lightweight 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 seamless connection between SAE-standard NPT cooling lines and metric LS sensor bosses, eliminating leak points and simplifying wiring harness integration. ICT BILLET's billet aluminum construction delivers superior durability and thermal stability compared to cast alternatives, resisting corrosion and vibration loosening in high-performance environments. The compact footprint (2.85 x 1.1 x 4.2 inches) fits tight engine bay layouts without requiring extensive re-plumbing.

This adapter is essential for builders converting carbureted or fuel-injected SBC engines to LS architecture, particularly those retaining original coolant system designs or custom radiator setups. Installation requires no special tools—standard wrenches and basic plumbing knowledge suffice. Pairing this adapter with your temperature sensor ensures accurate ECU feedback for proper fan cycling, fueling, and ignition timing. Verify your specific LS platform variant and coolant line diameter before ordering to confirm compatibility with your swap configuration.
