2000-2002 Mack RB Radiator - OEM
Direct replacement radiator engineered for Mack RB chassis trucks. Heavy-duty core construction built to handle stock cooling demands in commercial duty cycles. OEM-spec performance without the dealership markup.
Will this bolt straight into my truck without modification?
Yes — mounts at factory points with OEM bracket compatibility. Your existing hoses and tank connections align without fitment work.
Does this radiator come with a new thermostat or bypass block?
Radiator assembly only. You'll need to source a new thermostat and gasket separately if your existing ones show wear.
What's your return window if it doesn't fit?
Test-fit before final installation — once coolant is run through the core, it cannot be restocked. Confirm OEM part number match with your truck's documentation first.
