2010-2018 Toyota Sienna OEM Radiator - Automatic Transmission
Factory Toyota radiator engineered for the Sienna's cooling demands. Direct replacement keeps your van's temperature stable whether you're hauling passengers or highway miles. Built to handle the automatic transmission cooler loops without compromise.
Do I need to replace the hoses when I install this radiator?
Not necessarily — if your existing hoses are in good shape, they'll connect right up. Inspect them for cracks or soft spots before reassembly. If they're cracked or leaking, replace them at the same time.
Will this work with a transmission cooler flush, or do I need to drain the system?
You'll need to drain the coolant to swap the radiator out. Your transmission fluid stays in the cooler loop — just work carefully during removal and installation to avoid spills.
What about the fan and shroud — do those transfer over?
The fan and shroud from your old radiator will bolt to this one the same way. No new hardware needed there — just unbolt them from the old unit and bolt them on the new one.
