Is Your Toyota Yaris Cooling Fan Broken? Check This Relay First!

Welcome to another episode of The Eight Nine Garage. In this video, we are diving into the engine bay of my 2007 Toyota Yaris to replace the high-speed cooling/radiator fan relay. If your fan isn't kicking on high or your car is starting to run hot at idle, this simple relay swap might be your fix. Part Numbers Used: OEM Denso: 90987-04004 AKA: 156700-0860 Get yours here: https://amzn.to/3O6UjCA Tools Needed: Your fingers Steps covered: Identifying the correct relay box location. Locating the high-speed fan relay. Removing the old Denso unit. Installing the new 90987-04004 relay. Testing the fan operation. Disclaimer: Work on your vehicle at your own risk. Always ensure the engine is cool before working near the radiator or fan assembly.
