Cummins Radiator

Yes. SPELAB's direct-fit aluminum radiators replace thin-wall copper/brass factory units with thicker aluminum construction and more rows of cooling tubes. On the 2013–2018 6.7L Cummins, the factory radiator struggles under the heat loads generated by tuned horsepower and sustained towing. SPELAB's $309.99 unit drops operating temps measurably in summer heat, especially when paired with an upgraded fan clutch and auxiliary transmission cooler.

The 2010–2012 Ram 6.7L uses a different grille opening and mounting bracket configuration than the 2013–2018 trucks due to the front fascia redesign. SPELAB's radiators are model-year specific: $267.77 for 2010–2012 and $309.99 for 2013–2018. The two are not interchangeable. Verify your exact model year before ordering—if you have the older 2010–2012 style, the mounting points are in different locations on the core support.

An upgraded radiator helps with heat dissipation, but overheating has multiple causes. Before buying a new radiator, check: coolant level and condition, thermostat operation, fan clutch engagement, radiator airflow (clogged grille or debris), and transmission cooler line routing. On the 6.7L Cummins, a failing water pump or collapsed hose can mimic overheating symptoms. Diagnose the root cause first—if the radiator itself is the culprit, SPELAB's direct-fit replacement resolves it.

Installation is straightforward for experienced DIYers but takes 2–4 hours. Drain the coolant, disconnect the upper/lower hoses and fan shroud, remove the old radiator, and transfer the fan shroud and any sensor hardware to the new unit. Use new hose clamps and coolant at reassembly. On the 2013–2018 trucks, the intercooler is mounted in front of the radiator—handle both as one assembly. Professional install typically runs $150–$250.

Yes—if you're already in the engine bay for a radiator swap, it's the ideal time to upgrade related cooling components. Consider: new coolant (use Ford/Mopar spec), new thermostat and housing, coolant reservoir inspection, and fan clutch check on 2010–2012 trucks. SPELAB also offers coolant reservoirs and hose kits for the 6.7L Cummins that pair well with the radiator upgrade. Tackling all cooling components at once prevents repeat labor costs.
