QuickCar Racing Products 3/8" NPT 235°F Water Temperature Switch 61-748

Engine overheating can destroy a motor in minutes—this water temperature switch gives you real-time warning before catastrophic failure occurs. By activating a dashboard warning light at 235°F, you'll catch rising temps before they cause damage, giving you the critical seconds needed to back off throttle or pull off track. If you're running a race car, street machine, or high-performance build with a QuickCar gauge panel, this switch is essential safety equipment.

The 3/8-inch NPT male thread installs directly into your cooling system's hottest point—typically the intake manifold or cylinder head—where it monitors actual engine temperature rather than coolant tank readings. Its electric operation integrates seamlessly with QuickCar gauge panels and Quick-Light warning kits, eliminating the need for mechanical gauges or aftermarket wiring. Installation is straightforward: apply thread sealant, bolt it in, and connect the electrical leads to your warning circuit.
