Frequently Asked Questions About Kenworth T680 Radiators

What year models of Kenworth T680 trucks are these radiators compatible with?

Our Kenworth T680 radiators are designed to fit model years 2013 through current production. However, there are variations between early models (2013-2016) and later models (2017+) due to changes in mounting brackets and inlet/outlet configurations. Always verify your specific truck's VIN and engine type before ordering, as radiator compatibility can vary based on whether you have a Paccar MX-13, Cummins ISX15, or other engine options.

Are these aluminum or plastic tank radiators, and which is better for my T680?

We carry both aluminum core radiators with plastic tanks and all-aluminum radiators. Plastic tank radiators are typically OEM-style and cost less upfront, lasting 5-7 years under normal conditions. All-aluminum radiators are more durable, handle temperature fluctuations better, and can be repaired if damaged, making them ideal for heavy-duty applications or extreme climates. Consider all-aluminum if you frequently haul heavy loads or operate in harsh conditions.

How difficult is it to install a replacement radiator in a T680, and what tools do I need?

Installation typically takes 3-4 hours for experienced mechanics and requires basic hand tools, including socket sets, pliers, and drain pans. The main challenges include properly draining and refilling the cooling system (approximately 11-13 gallons), ensuring all mounting brackets align correctly, and reconnecting transmission cooler lines without cross-threading. We recommend having a second person help position the radiator during installation, as they can weigh 40-60 pounds depending on the model.

What are the most common signs that my T680 radiator needs replacement?

Key indicators include coolant leaks (especially at tank seams or around the inlet/outlet), engine temperatures running above 200-210 degrees Fahrenheit during normal operation, visible fin damage blocking more than 20% of airflow, or coolant contamination in your transmission fluid. Additionally, if your radiator is over 500,000 miles or 7 years old, preventive replacement during scheduled maintenance can avoid costly roadside breakdowns.

Do these radiators come with mounting hardware and gaskets, or do I need to order separately?

Most of our T680 radiators come as core units only, meaning you'll need to reuse existing mounting brackets, rubber isolators, and hose clamps from your original radiator. We recommend replacing rubber mounting cushions and hose clamps during installation for optimal performance. Radiator caps are typically sold separately and should be replaced with the correct pressure rating (usually 15-16 PSI for T680 models) to maintain proper cooling system pressure.
