Frequently Asked Questions
Will this bolt directly into my vehicle without modifying hoses or brackets?
Yes. This radiator mounts at the factory attachment points using the original bolt locations. Your existing hose routing and fan shroud stay as-is—no modifications needed.
Do I need to flush the cooling system before installation?
Drain and flush the old coolant from your system before the new radiator goes in. This prevents debris from clogging the new core and ensures fresh fluid chemistry.
What if the radiator leaks within the first month?
Return it within 30 days for a replacement. Test-fit and pressurize your system during initial startup to catch any shipping-related defects early.
