Hello everyone today I tried to burp my coolant to get any air pockets out after turbo replacement but noticed the radiator fans don’t come on at all regardless of temp or hard drive. I live in florida so it gets pretty hot here and the fans never turn on even after hour drives in 85+ weather. The fans both come on everytime I turn on Ac but never kick on after or during drives when at operating temp. I’m wondering if this is an issue or if this is just how the RDX’s cooling system functions.

 

Have you looked at the water temp gauge to see where it's at while driving in hot weather? My temp gauge never rises above typical running temp range unless going up steep hills on hot days and the fan does come on but I don't know if the AC is also engaging at the same time.
