### ⭐⭐⭐ Radiator came with dent
*by G***Y on September 16, 2025*

I ordered this Radiator three days ago received it to today September 16-2025. The three stars are because right out of the box there's a good size dent look at photos, but I can see it's well built so I installed it in my Hummer H 3 fits perfectly let truck run for 40 minutes with heater on got all the air out of the system and it's keeping the temperature gage less than half way great but l will wait to see if it holds up if so I will change my rating.
