In the heat of a race, a driver’s eyes are fixed on the track ahead, not glued to a tiny needle on the dashboard. By the time a driver notices their water temperature gauge is pegged in the red, it is often too late—the engine has already overheated, resulting in blown head gaskets or warped cylinder heads. The Longacre 230º Water Temperature Sender is the critical first line of defense designed to prevent catastrophic engine failure.
This specialized sender acts as a fixed-temperature switch. It is factory-calibrated to instantly close the circuit and trigger a bright dashboard warning light the exact moment the engine coolant hits a dangerous 230º F. Featuring a standard, robust 1/2" NPT threaded base, it installs cleanly into common water jacket ports on most V8 intake manifolds or cylinder heads, providing immediate, automated overheat protection for high-stress racing engines.
Key Features
-
230°F Activation Point: Precision-calibrated to send an immediate electrical signal the moment coolant reaches the critical 230°F threshold, giving the driver crucial seconds to pull off the track or activate secondary cooling fans.
-
Standard 1/2" NPT Fitment: Engineered with a 1/2-inch National Pipe Thread base, allowing it to screw directly into standard domestic V8 intake manifolds and aftermarket water neck housings without requiring specialized adapters.
-
Insulated Blade Terminal: Features a secure, vibration-resistant insulated blade terminal for fast, reliable wiring to any standard 12-volt dashboard warning light circuit.
-
Harsh Environment Durability: Built to withstand intense under-hood radiant heat, violent chassis vibrations, and highly pressurized racing coolant systems without failing or leaking.
