Core
Recoring a Heavy Truck Radiator: What to Check First
Start by inspecting the tanks, header plates, and side channels. If they are free of cracks and heavy rust, the radiator is a good candidate for a new core. Next, record the core height, width, and thickness without the tanks. Count the tube rows and note the fin density. Then match the truck make, model and year, as one truck series can use more than one core size across model years. Refuses and fire trucks idle for long periods in traffic, so a properly sized core is important for steady cooling. Finally, compare your measurements with the listed sizes before ordering.Request a Quote for Truck Radiator Cores

Radiator core replacement, or recoring, means removing a worn core and fitting a new one into the original tanks and header plates. The truck keeps its factory mounting points and hose connections. Workshops use this method on heavy truck radiators because it restores proper cooling performance without buying a completely new radiator assembly.
Yes, recoring a truck radiator is worth it when the tanks, header plates and side channels are still in good shape. A new core costs less than a complete heavy-duty assembly and keeps the original mounting and connections. If the tanks are cracked or badly corroded, a full radiator replacement is usually the better option.
These radiator cores fit Freightliner Columbia 112 and 120, FLA, FLB, FLC, FLT series, FL60, FL70, FL80, FLD120, FLD132 and M2-106 trucks built between 1990 and 2005. Several different part numbers cover this truck group, so check your truck year, model, engine and current core size before submitting an enquiry.
Yes, the collection includes radiator cores for the Mack MR 600 sanitation truck, with listings covering 1999 to 2007 models. There are also cores for the Mack LE 600 from 2000 to 2007. Compare the part number and core dimensions with those of your existing radiator, as refuse truck cooling packs vary by year.
GMC Brigadier fire truck radiator cores are available in two sizes: 1003 x 688 x 61 mm and 1054 x 688 x 61 mm. Their part numbers are 6560475-200 and 6560476-200. Measure the height of your old core carefully because the two sizes differ mainly in length and are easy to mix up.
You measure a truck radiator core by recording its height, width, and thickness with the tanks removed. Measure between the header plates for height and across the fins for width. Then count the tube rows and note the fin spacing. Provide these figures with the truck model and year to confirm the right core.
A heavy truck radiator core fails primarily due to internal scale, external corrosion, clogged fins, and vibration fatigue. Poor coolant and hard water build deposits inside the tubes. Road grime blocks airflow. Stop-start duty, common for refuse and fire trucks, adds heat stress. Over time, tubes crack and leak, and the core needs replacing.
The radiator cores in this collection are supplied by a cooling products manufacturer in Ajman, UAE, operating since 1986. The manufacturer holds ISO 9001, ISO 14001, and ISO 45001 certification. Its aftermarket cores serve trucks, buses, and heavy equipment. Confirm dimensions and cross-references before ordering.
