Hey guys, so i had to replace my radiator and got a Spectra CU13476. I installed it and everything fit perfectly up until i realized that there's a hole I'm guessing for a sensor of some sorts but the old radiator didn't have it so really dont want to pull it out again and get a different radiator and put it back in. Does anyone in here know what type of sensor goes in there or maybe there's a way to block it off somehow? Thank you.
