Frequently Asked Questions
Will this radiator bolt directly to my engine bay without adapter fittings?
Yes. This unit mounts at factory points and connects to OEM hose locations. Your existing cooling lines and brackets will align without modification.
Do I need to flush my cooling system before installation?
Flush your system thoroughly with distilled water to remove old coolant and sediment. Fresh fluid prevents corrosion and ensures the new radiator operates at peak efficiency.
What's the return process if the radiator doesn't fit after I receive it?
