Finally! A thermal switch for LS that's the correct metric thread, at a reasonable price. These screw directly into the cylinder head at the factory temp sender location. NO ADAPTERS NEEDED! Most vehicles have one of these ports available. No more sticking a temp bulb through the radiator.

Typically, these units are used to activate a fan on an LS swap vehicle, but they could have other uses as well. This unit is rated to close the circuit at 190*. We use these to supply ground to either the fan or fan relay, but it's rated to 30 AMPs for use on the positive side as well.
