Frequently Asked Questions
Will this radiator work with my current hoses and clamps?
Factory radiator uses standard hose connections. Existing hoses fit the barbed ports—no adapters needed. Inspect hose condition before install; RAM cooling systems run hot, and deteriorated hoses fail fast.
Do I need to flush the system before installation?
Yes. Old coolant can hold sediment and corrosion particles that clog a new core immediately. Run a system flush, rinse with distilled water, then fill with fresh coolant rated for your engine.
What's the return window if this doesn't fit?
Check your engine displacement and confirm it matches one of the three covered: 3.7L, 4.7L, or 5.7L. If fitment is wrong after verify, contact support with photos of your engine bay for next steps.
