• Cracked plastic tanks or weakened seals on the original unit
• Fitment issues caused by non-OE-style replacement radiators

Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line routing, and overall core dimensions before installation. Inspect hoses, clamps, and mounting points for wear, and flush the cooling system if contamination or internal debris is present. This radiator is a direct replacement for the 2006 Toyota Sienna, N/A, so installation should follow factory service procedures for coolant fill and air bleeding.
