DENSO Auto Parts Radiator P/N:221-3503
DENSO Auto Parts 221-9320 radiator for the 2013-2015 Cadillac ATS 4-cylinder 2.5L cools engine coolant as it flows through the core. Its tanks, fin pitch, core dimensions and materials are built to OE manufacturer standards.
A failing radiator can show up as coolant seepage, damage to the core or an engine that runs hot. A hot-running engine alone does not prove the radiator is the problem, because a weak water pump could be behind it too.
This radiator fits the 2013-2015 Cadillac ATS 4-cylinder 2.5L.
