Frequently Asked Questions
Will this bolt directly into my car without any modifications?
Yes. This radiator uses factory mounting points — no drilling, welding, or bracket modifications needed. It slides into the same location as the original unit.
Do I need to flush my cooling system before installing this?
Flushing your system before install is a solid move. Old coolant can carry debris that clogs a new radiator. Use a coolant flush kit, drain completely, rinse the lines, and fill with fresh coolant per your vehicle's specification.
What if the radiator arrives damaged or doesn't cool properly after installation?
Contact our support team with photos of the damage or a description of the cooling issue. We'll document it and work out a replacement or return based on what we find. Keep your shipping box and packaging for inspection if needed.
