16-21 Lexus GS/RC200T/RC300 OEM Radiator
Direct OEM replacement radiator for GS and RC models, engineered to factory specifications. Maintains proper coolant flow and thermal regulation without modification to existing mounting or plumbing. Ready to install as a drop-in swap for original equipment.
Do I need to flush the cooling system before installing this?
Yes. Drain the old coolant completely and flush the system with distilled water to remove debris and sediment. Refill with fresh OEM or equivalent coolant to spec.
Will the original hose clamps and fittings work with this radiator?
The connection points match factory spec, so your existing upper and lower radiator hoses will fit. Inspect clamps for corrosion or wear — replace if necessary to avoid leaks.
What if there's a coolant leak after installation?
Check hose clamp tightness first — vibration can loosen them over time. If leaking persists at fitting seals, the hoses may be worn. Verify all connections are hand-tight before pressurizing the system.
