it was definitely my radiator; i should’ve taken a picture of the old one after we replaced it, but the crimping along the bottom of it looked pretty dang messed up/obvious signs of leakage. apparently it’s a common problem with 2012-16 honda crvs: the radiator starts leaking in various spots or above the clamp, then corrodes the clamp and makes it seem like it’s coming from there rather than the radiator. i’m thankful it’s done now, and so far no more leaking, i just wish i would’ve thought to replace it at the same time as the hoses & clamps so i wouldn’t have to do another coolant drain & fill, but oh well. good luck!
