Direct replacement radiator engineered for the 3.8L V6 engine in your Genesis Coupe. Built to factory specifications, this unit handles full cooling capacity without modification. Drop-in fit at original mounting points.
Do I need to drain and flush the cooling system before installation?
Yes. Disconnect both hose clamps, drain coolant into a catch pan, then remove the radiator from its brackets. Flush the system before installing the new unit to remove debris and old fluid.
Will this radiator work with my current hoses and clamps?
The connection ports match factory spec, so your existing hoses should fit. Before tightening, confirm hose diameter and condition—if clamps are corroded or hoses show cracks, replace them at the same time.
What if the radiator leaks after installation?
Check hose clamp torque first—overtightening can crack aluminum. Also verify that both hoses seated fully into the ports. If leaking persists, contact ModSupply with proof of purchase for return evaluation.
