We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It transfers heat from the engine coolant to the outside air, preventing overheating under load. You typically replace the original radiator when it leaks, becomes clogged, or is damaged in a collision. This style commonly uses an aluminum core with plastic tanks for lighter weight and good heat dissipation.
