Sizing Up A Heavy Duty Radiator Core

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.

Start by measuring the core height, which is always the distance between the headers. Next measure the core width – do not include the side rails. Next determine the depth by inserting a thin wire between the fins and the tubes and note that measurement. It’s critical to determine for a heavy duty truck radiator core the number of rows, tube size, distance between tubes, the type and number of fins per inch and whether the core is centered on the headers or whether there is an offset. If it’s a bolt-on heavy duty truck radiator tank, a bolt pattern will generally be required. If it’s a solder-on heavy duty truck radiator tank, the corner radii will generally be required. All of this data must be accurately determined prior to fabrication of the heavy duty truck core.

The best way to insure that the heavy duty truck radiator core measurements and characteristics are accurately determined, and to insure that your Freightliner, Peterbilt, Kenworth, Mack, John Deere or CAT is properly cooled, is to have your heavy duty truck radiator service facility do it for you. That way you know it’s been done right.
