Check the Outlet Type Before You Order
The KEN18 has a flanged outlet. Kenworth trucks in this range often share the same core size but use different hose connections, so compare yours against your old radiator. The KEN06 has the same 40″ x 28″ core with a curved inlet and non-flanged 3″ outlet. The KEN12 is for T600, T660 and T800 trucks with angled 2-1/2″ connections.
Alternate Core Options
Need a different core? The KEN09 is a 1-7/8″ three-row core, and the KEN31 is a 2-7/8″ five-row flat fin core. Send us your truck’s year and model and we’ll confirm the right one.
Built for Heavy Kenworth Workloads
Kenworth T800 and W900 trucks run long hours under heavy loads, and a weak radiator is a common cause of overheating. Our guide to common heavy-duty truck radiator problems and fixes covers the warning signs to watch for.
Replace or Repair Your Kenworth Radiator?
If the damage is limited to a tank or part of the core, repair may cost less than a new unit. See our repair vs. replacement cost guide, or ask about our heavy-duty truck radiator repair and rebuilding and radiator re-coring services. If the radiator is beyond repair, the KEN18 is ready to order.
