Oil Thermostat

The EARLS Oil Thermostat (model 501ERL) is a remote-mounted oil temperature control device designed for automotive enthusiasts and performance mechanics who require precise oil temperature management. This thermostat is installed between the engine and oil cooler, effectively regulating oil flow based on oil temperature to maintain optimal viscosity and protection under various driving conditions.

Constructed from black anodized aluminum, the EARLS Oil Thermostat features dual 10 AN female O-ring inlet ports and a 10 AN female O-ring outlet, allowing for flexible plumbing configurations in tight engine bays or custom cooling setups. The aluminum material offers excellent thermal conductivity and corrosion resistance, while the anodized finish protects against oxidation in aggressive environments. Mounting is straightforward with standard 1/4-inch holes, enabling easy installation on custom brackets or existing frame points.

This remote oil thermostat is ideal for high-performance builds, including drift cars, road-course competitors, LS-swapped platforms, and turbocharged street machines where factory cooling systems may be inadequate. The 10 AN O-ring SAE ports integrate seamlessly with industry-standard hose and fitting systems, making it a practical choice for both new builds and modifications.
