Will this radiator fit my truck without modifications?

This is a direct-replacement radiator designed for factory mounting points. No drilling or fabrication required — it bolts in using the original locations.

Do I need to flush my cooling system before installation?

Yes. Flush the system thoroughly with distilled water before installing the new radiator. Old coolant and debris can restrict flow and damage the new core.

What coolant should I use after installation?

Use the coolant type specified in your vehicle's owner manual — typically Mopar or an equivalent heavy-duty diesel coolant. Don't mix types or use standard passenger-car coolant in a diesel engine.
