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.
Time Delay Relay
Time delay relay is a normally closed bi-metallic switch. It is grounded through its housing and completes a circuit from battery through ignition switch or from battery through ignition switch and CEC solenoid, depending upon engine temperature and transmission gear position. Bi-metallic coil opens approximately 20 seconds after ignition key is turned on, providing engine temperature is above 82°F, or for approximately 20 seconds after engine temperature switch "cold" override points open. Vacuum to distributor for this time interval improves driveaway and eliminates stall after start tendencies.
