Heater Core for 2013-2019 Kenworth T680 & More - Four Seasons 96141

Keep warm air flowing to the cab with the Four Seasons heater core (P/N 96141), an aluminum core that transfers heat from the engine's hot coolant to the air your blower pushes through the dash vents. It drops in as a direct-fit replacement for the 2013-2015 Kenworth T660, the 2013-2019 Kenworth T680, and the 2013-2019 Peterbilt 579 — see the Buyer's Guide tab for the full engine breakdown.

• Aluminum core: aluminum construction for the heat-transfer job.
• Heavy-duty build: heavy-duty construction for product durability.
• O.E. fit, form & function: quality-engineered to match the original component.
• Independently tested: independently tested for proven quality and performance.

If your rig blows cool air when the heat is turned up, fogs the windshield, leaves a sweet coolant smell in the cab, or drips coolant on the floor, a failed heater core may be the cause — and this heater core replaces it. Always diagnose the source of the leak or heat loss before replacing.
