SPAL's fan relay harness are a must have when installing an electric fan for your water or oil cooling systems. A fan relay reduces amp loads from the cooling fans by only having them run when they are needed and allow the engine to quickly warm up to operating temperature. These relays can also be used as safeguard from driver/co-driver error by ensure the cooling fan is always on without having to toggle a switch. These kits feature a waterproof 40/50 amp relay that can be easily installed into any OEM or custom wiring loom. The kits are available with and without thermostat sensors. The sensors are 3/8" NPT thread and are available as 185_ or 195_. The kits are design to turn on a fan at a set temperature and turn it off 20 degrees lower than the setting. The kits also feature an optional switched override that allows you to turn on the fan when you want it to come on.
