Frequently Asked Questions
Will this bolt straight into my car without modifications?
Yes. Factory mounting points align with OEM design—no drilling, bending, or adapter brackets needed. Bolt it in place using existing hardpoints.
Do I need to flush the system or use a specific coolant type?
Flush the cooling system before installation to remove old debris and sediment. Use the coolant type specified in your owner's manual—do not mix types.
What if the radiator fails after I install it?
Contact ModSupply's support team with proof of purchase and details of the failure. Warranty coverage and return options depend on the timeline and condition of the unit.
