Direct OEM replacement radiator for V6 Highlander models—maintains factory cooling capacity and fitment without modification. Built to handle highway heat and city traffic with the same core design and tank construction as the original. Tested for proper thermostat response and leak-free operation before shipment.
Do I need to flush the cooling system before installation?
Flushing your system before the swap is smart practice—old coolant can carry debris that clogs a new radiator. Drain the system, run distilled water through it once or twice, then refill with fresh coolant and proper concentration for your climate.
Will this work with my existing hoses and clamps?
Yes. The inlet and outlet tank ports match OEM placement, so your existing hose diameters and clamp hardware will bolt up without modification. Inspect hose condition while you're in there though—if they're original to 2008–2013, replacement is worth the peace of mind.
What if the radiator leaks after installation?
Every unit is pressure-tested before it ships, so leaks out of the box are extremely rare. If one arrives damaged or fails immediately, contact ModSupply support with photos and your order number for resolution options.
Products are direct shipped from Supplier.
