Frequently Asked Questions About Kenworth T880 Radiators

What year models and engine types are compatible with T880 radiators?

T880 radiators are designed for models from 2013 to present. Compatibility depends on your specific engine configuration - Cummins ISX15, X15, and Paccar MX-13 engines each require different radiator specifications. Always verify your engine serial number and cooling package code (found on your door jamb sticker) before ordering, as heavy-haul and vocational models may have different cooling requirements than highway tractors.

Are aftermarket T880 radiators as durable as OEM, and what materials should I look for?

Quality aftermarket radiators can match OEM durability when built with the right materials. Look for radiators with aluminum cores featuring 2-row or 3-row tube designs, reinforced plastic or aluminum tanks, and brazed (not epoxied) tank-to-core connections. Heavy-duty models should have a minimum core thickness of 2 inches. Avoid radiators with crimped-only connections or thin-gauge aluminum, as these tend to fail prematurely in demanding applications.

What are the most common installation challenges and how long does replacement take?

Installation typically takes 3-4 hours for experienced technicians. Common challenges include: disconnecting the charge air cooler (CAC) assembly, properly routing coolant hoses to avoid kinks, and ensuring correct fan shroud alignment. Some models require removing the front grille and hood-mounted accessories. Have new coolant, hose clamps, and radiator mounting bushings ready, as reusing old components often leads to leaks. The upper radiator support may need adjustment on older trucks due to frame settling.

What causes premature T880 radiator failure and how can I prevent it?

The most common failure points are: silicate dropout from improper coolant causing tube blockage, pressure cycling damage from faulty radiator caps, and vibration-related cracks at mounting points. Prevent these issues by using only approved extended life coolant (ELC), replacing radiator caps every 2 years, checking mounting bushings annually, and maintaining proper coolant levels. Winter operation requires extra attention to prevent freeze damage from diluted coolant.

Should I replace other cooling system components when installing a new radiator?

Yes, replacing related components prevents comeback failures. At minimum, install a new radiator cap, thermostat, and upper/lower radiator hoses. For trucks over 500,000 miles, also consider replacing the water pump, coolant overflow tank, and heater hoses. Always flush the entire cooling system before installation to remove debris that could clog your new radiator. Budget an additional $150-300 for these supporting components to ensure reliable operation.
