Four Seasons HVAC Heater Core P/N:98466

Keep warm air flowing into the cabin with the Four Seasons heater core, part number 98466, an aluminum core that carries hot engine coolant inside the HVAC housing so the blower can deliver heated air to the cabin. It fits many vehicles, among them the 1994-2002 Dodge Ram 1500, 1993-1998 Jeep Grand Cherokee and 1994-2002 Dodge Ram 2500. See the Buyer's Guide tab for every other vehicle it fits.

Four Seasons draws on more than 50 years of mobile A/C experience and engineers and tests this core with the aim of years of trouble-free operation as a direct-fit replacement for the listed applications.

• Aluminum heater core: transfers heat from the engine's coolant to the air moving through the HVAC system.
• Heavy-duty construction: built with durability in mind.
• Quality engineering: designed for O.E. fit, form and function.
• Independently tested: checked for quality and performance.

A heater core sits in the coolant circuit, so a leak or blockage can affect both cabin comfort and coolant level. Signs it may need replacing include weak or no heat from the vents, a sweet coolant smell in the cabin, fogged windows, damp floor carpet or unexplained coolant loss. If a failed core is the cause, this unit replaces it. Diagnose the problem first, because thermostat, blend-door and other cooling-system faults can cause similar symptoms.
