When a heavy duty radiator core has to be replaced, whether it’s a Freightliner, Peterbilt, Kenworth or Mack heavy duty truck, or a John Deere tractor or a CAT loader, it’s critical that all of the core measurements are accurate. If the heavy duty truck core measurements are inaccurate, reassembly will be difficult at best, or impossible without re-fabrication, possibly leading to serious cooling problems. read more

Class 6, 7 and 8 heavy-duty truck radiator cores are composed of headers, fins and tubes which are subject to a variety of punishing over the road conditions. There’s the constant barrage of debris and other larger objects, jolts from irregular road surfaces and the endless flow of air through the body of the core. The relentless airflow around radiator tubes manufactured from inferior and thinner gauge materials will cause the tubes to erode quicker than those manufactured with heavier gauge, better quality materials. That erosion will eventually cause tube punctures and leaks. Heavier gauge fin material will decrease the possibility of fin tearing which causes reduced fin surface, loss of heat transfer and over-heating.
