Frequently Asked Questions
Will this radiator work with my factory fan shroud and hoses?
Yes — this is a direct OEM replacement. Your existing fan, hoses, and mounting hardware bolt up without modification. Drain your coolant, unbolt the old unit, and install the new one using the same fastener points.
Do I need to flush the system before installing this?
Absolutely. Run a coolant flush to remove sediment and debris from the old radiator and lines. Any contaminants left behind will clog the new core and tank. Use the cooling system capacity specified in your service manual and recommended coolant type for your year.
What if my radiator leaks or fails after I install it?
Contact our support team with photos of the failure and your order number. We handle defect claims directly — no runaround. Warranty coverage is subject to proper installation and coolant maintenance.

Can I install OEM parts myself, or is it better to have a professional handle it?
