Replaced my aging radiator with a CSF this past Friday. All went well with the install and had no issues driving the rig the past few days. Went out today and noticed fluid under the truck. To my surprise, the CSF has sprung a few leaks along the lower passenger side coils and a small pinhole on the left side. Spotted a few more little weeps along the perimeter as well. Oh well. OEM going in next.
