Leaked within 1000 miles
This radiator was shipped quickly and arrived well packaged. It was an exact fit and installed in about an hour. Unfortunately, within a few months it developed a small leak around the upper hose jacket which once fully warm and pressurized, leaks to the extent it is undrivable.
I contacted 1aauto, explained the issue and they promptly shipped a new one without any hastles.
