Factory replacement radiator engineered for 4.3L V6 cooling system demands. Built to OEM specifications and ready for direct installation. This is a complete radiator assembly—no modification needed.
Will this bolt straight in, or do I need to modify my truck?
This radiator mounts at factory points using existing brackets—no drilling or frame modification. Disconnect your old hoses, unbolt the core, and reverse the process with the new assembly.
Do I need to flush my cooling system before installation?
Flush the system before you install this radiator. Old coolant debris will clog the new core and kill your warranty instantly. Run distilled water through until it runs clear, then refill with fresh coolant.
What if the radiator arrives damaged or fails after installation?
Inspect the unit before you install—damage in shipping is covered on return or replacement. Failures after install are handled case-by-case; contact support with photos and install details for evaluation.
Products are direct shipped from Supplier.
