Frequently Asked Questions
Will this bolt straight into my existing radiator mounts?
Yes — this is factory geometry, so it uses the OEM mounting points. No drilling or frame modification needed. Your existing hoses and shroud will align as they did before.
Do I need to flush my cooling system before installing this?
Absolutely. Run a quality flush and refill with fresh coolant rated for your engine. Old sediment and contaminants will clog a new radiator fast and void reliability.
What if the radiator arrives with damage or fails shortly after install?
Contact ModSupply within 30 days of delivery with photos and detail. Defects are handled directly — we ship from Florida and process claims without manufacturer runaround.
Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
