Hi, I have a 2007 Lexus ES350 with 57,548 miles that has developed some kind of coolant leak that causes coolant to seep from the top of the radiator. I also notice occasional steam / evaporation of coolant from the radiator grille and have to occasionally top off the coolant (I have been using the Walmart Supertech OE Red Antifreeze Prediluted 50/50) as the reservoir empties. Also, last night I saw coolant on the floor of my garage. No overheating on the temperature gauge. Is this a bad radiator or something entirely else? Do I need to just replace the radiator?
Some photos of inside the engine bay (apologizes for if I did not link properly):

Well yeah, if coolant is seeping out of the radiator of course it needs to be replaced. Not unusual for a 16-year-old vehicle. (The only other issue would be if the coolant is spraying on there from somewhere else.)
Thanks. It looks like it might have just been the radiator. I used the UV glasses and a black light to see if it was coming from somewhere else but I didn't notice anything; I ended up replacing it myself last night with a Denso 221-3158 unit and replaced the upper radiator hose as well (lower one was too hard to remove). Used the Supertech Red Coolant to refill it since that's what I had. It took me from 6pm until 4 am to complete it, it was not easy as I thought it was. Hopefully it resolved the issue going forward.
