Dual Activation/Dual Fan Relay Kit on 185 off 175

The Painless Wiring Dual Activation/Dual Fan Relay Kit on 185 off 175 is designed for automotive enthusiasts and professional mechanics who require precise engine cooling control in high-performance or modified vehicles. This relay kit addresses the challenge of managing dual electric cooling fans with independent activation thresholds, ensuring optimal radiator performance without electrical strain.

Built by Painless Wiring, a trusted name in automotive electrical integration, this dual relay system activates the first cooling fan at 185°F and includes a second fan activation threshold, which is not specified in the original description. This design prevents thermal cycling while protecting against overheating, and the separate relay configuration isolates each fan circuit, reducing electromagnetic interference and minimizing voltage drop.

Ideal for street rods, restorations, LS engine conversions, and any modified vehicle where factory thermal management is insufficient, this relay kit integrates cleanly into engine bays. The compact form factor and lightweight design ensure no penalty to vehicle dynamics or mounting complexity, making it a valuable addition for installers looking to enhance cooling performance.
