Frequently Asked Questions
Do I need to flush my cooling system before installing this radiator?
Yes. Drain old coolant completely and flush the system with distilled water to remove sediment and debris. Install fresh coolant per your vehicle's specification after radiator installation.
Will the factory hose clamps and hoses work with this radiator?
Your existing hoses will connect directly to the inlet and outlet ports. Clamps reuse without issue. Inspect hose condition while you're in there—if they're original or cracked, replace them now rather than later.
What if the radiator leaks after I install it?
Contact ModSupply with photos of the failure point and your order number. Defects caught within the return window are handled on a case-by-case basis.
