Spectra Premium Radiator P/N:CU2339
Spectra Premium CU2925 radiator for the 2005-2006 Toyota Sienna V6 3.3L carries engine coolant through its core so the engine sheds heat. The structure and design of this Spectra Premium radiator are built to meet the same durability expectations as the OE.
Coolant stains on the core or tanks, a cracked plastic tank, or a temperature gauge that runs high can mean the radiator is failing. With the engine off and cool, a look at the core and tanks is a sensible first check. A high gauge alone does not prove the radiator is at fault, since a worn thermostat can cause it too.
This radiator is a direct-fit replacement for the 2005-2006 Toyota Sienna V6 3.3L, and that vehicle takes one.
