Your radiator is one of the hardest-working parts on your Kenworth. It keeps your engine from overheating, even when you're hauling heavy loads through tough terrain or high temps. If it fails, your rig won’t be going far. That’s why investing in a reliable aftermarket radiator is a smart move.

Why Buy Aftermarket Radiators for the W900b/900l Kenworth?

- Built Tough:Plastic and aluminum cores offer strength without extra weight. - Better Cooling:Boosts efficiency over old or failing OEM parts. - Easy Install:Designed to fit Kenworth W900B and W900L models seamlessly. - Options That Fit Your Setup:Available with or without oil coolers, surge tanks, or frames. - Long-Haul Tested: Made for commercial drivers who count on performance. While you're working on replacing the radiator, you can easily swap out nearby components that might be damaged, like the Kenworth AC condensor, located in front of the radiator, or radiator tubes and gaskets. Consider a comprehensive upgrade by adding new W900l fan shrouds to direct airflow effectively through your radiator, or replace your Kenworth w900b intercooler/charge air cooler for a more optimal thermal management system in your truck.

Here's What the Radiator Does

The radiator moves coolant through your engine to pull heat away and release it into the air. It helps your engine run at the right temperature—not too hot, not too cold. Without it? You risk breakdowns, engine damage, and big repair bills.
