Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cooling Fan Relays (9-5)
Two cooling fan relays are used on cars without A/C, one for low speed and one for high speed. On cars with A/C, three relays are used. They are located in power distribution box, on right rear of engine compartment behind battery. All relays are controlled by DICE (Dashboard Integrated Control System) via coolant temperature signals (also A/C pressure, vehicle speed and outside temperature on A/C equipped cars) received from Trionic Engine Management System.
