Spal 185FH Fan Relay And Wiring Harness Kit With 3/8" NPT Pipe Thread 185 Degree Thermostat Switch

Description : 

This kit includes a Spal brand sealed relay similar to Hella's 4RD 007.794-301 sealed 5 blade relays. This kit is for ONE fan!!

The 185TS single wire thermal switch turns the fan on at a temperature of 185 degrees and off at 165 degrees. It is 3/8" NPT pipe thread. The thermostat switch acts as a ground for a relay. As the thermostat reaches the appropriate temperature it completes the ground circuit for the fan relay, then activates your radiator or oil cooler fans.
