Installation Notes and Tips
Verify inlet and outlet orientation before installation: this radiator uses a left-side inlet and right-side outlet. Confirm core dimensions, hose routing, and mounting points against the original unit before removal. Transfer any required OE components from the original radiator if your vehicle setup calls for them, and refill the cooling system with the correct coolant specification after installation. Bleed air from the system thoroughly to help prevent hot spots and temperature fluctuations.
