Parts for your 2006 Subaru Tribeca-Radiator

2006 Subaru Tribeca Radiator — what it does and how to look after it

Yes, the 2006 Subaru Tribeca (B9) absolutely uses a conventional engine radiator. Technical references including the Subaru Factory Service Manual for the 2006 Tribeca (Cooling System section) and the Subaru parts catalogue (Group 45111: Radiator Assembly) identify and detail the radiator, associated hoses, cap, fans and, on many vehicles, an in‑tank heat exchanger for the automatic transmission fluid. These sources leave no doubt that a radiator is fitted and essential to the vehicle’s cooling system.

On the Tribeca’s 3.0‑litre EZ30 flat‑six, the radiator’s job is to shed engine heat by circulating coolant through an aluminium core with plastic end tanks, then dumping that heat to airflow while the fans and vehicle motion pull air through the fins. Many examples also route transmission fluid through a small heat exchanger in one of the end tanks
