Ensure the relay is properly attached to prevent relay “ thermal” shutdown and relay damage, resulting in possible engine overheating.įor installation, reverse the above procedure using new rivets included with the solid state relay Carefully drill out the two retaining rivets.ĬAUTION: The relay mounting location is designed to dissipate heat.Remove the left side headlamp bulb from the headlamp housing.Open hood, disconnect and isolate the battery negative cable.The headlamp module must be removed to access the relay. The radiator fan relay is located below the left front headlamp module. If the Radiator fan control module has failed you will need to replace it with a new one there is no way to repair it. If the resistance is greater than 1 ohm, repair the wire harness as necessary.Ĭheck the relay for the fans: (MOST LIKELY FAILURE AND MOST DIFFICULT).Also check for continuity between PCM connector terminal 43 and the sensor harness connector. Test the resistance of the wire harness between the PCM connector terminal 26 and the sensor harness connector.Room temperature around 70☏ ohmmeter should read approximately 7,000 to 13,000 ohms.Normal operating temperature around 200☏ ohmmeter should read approximately 700 to 1,000 ohms.Connect a high input impedance (digital) volt-ohmmeter to terminals A and B (Fig.Fig 96 Engine Coolant Temperature Sensor Connector
