Fan Relay With Thermost at 185/170 Deg

The Fan Relay With Thermostat at 185/170 Deg (RPCR3102) is a precision thermal management component engineered for high-performance automotive and tactical vehicle cooling systems. Designed by Racing Power Co-Packaged, this relay serves operators and technicians who depend on reliable engine temperature regulation under demanding conditions. Whether deployed in law enforcement pursuit vehicles, military transport, or aftermarket performance builds, this thermostat-controlled relay ensures your cooling fan engages at critical temperature thresholds—185°F primary and 170°F secondary—preventing engine overheat and maintaining system integrity during sustained operations.

This fan relay operates via dual-setpoint thermostat logic: the primary 185°F threshold activates cooling under standard operating loads, while the 170°F secondary setting ensures sustained fan operation during high-demand scenarios or ambient heat stress. The compact design (8.55 x 1.95 x 8.8 inches) integrates seamlessly into engine bay layouts without requiring extensive rewiring or modification. At just 0.74 lbs, the relay minimizes parasitic weight while delivering robust electrical switching rated for continuous duty cycles—critical in tactical and emergency-response vehicles where reliability cannot be compromised. Racing Power's manufacturing standard ensures consistent performance across repeated thermal cycles and extended service intervals.

Field personnel, fleet maintenance technicians, and performance automotive builders benefit most from this relay's straightforward installation and proven thermal accuracy. Law enforcement and military vehicle operators running upgraded cooling systems, auxiliary equipment, or operating in high-ambient environments will appreciate the dual-threshold protection against vapor lock and catastrophic overheating. Compatible with most domestic and import radiator fan motors, the RPCR3102 installs in the engine bay near the thermostat housing or fan shroud—verify existing wiring harness amperage ratings before installation to ensure safe circuit matching.
