Frequently Asked Questions
Will this bolt straight in, or do I need to modify any mounting?
Factory mounting points are preserved — this radiator attaches at OEM locations without drilling or brackets. Confirm your engine displacement matches before ordering.
Do I need to flush the cooling system before installing this?
Yes. Flush old coolant and debris from your block and hoses first. Old fluid can clog a new core quickly. Use distilled water and a flush kit if buildup is heavy.
What if the radiator leaks after I install it?
Check all hose clamps and tank connections for tightness — vibration during shipping can loosen fittings. If a seam leaks after that, contact our support team with photos for warranty evaluation.
