Product Details

Four Seasons Heater Core 98636 is engineered as an aluminum heater core for HVAC repair on older Dodge B-series vans and Plymouth PB vans. The compact core size and 0.625-inch tube connections support proper coolant flow through the heater system, helping restore cabin heat in 1978-1980 Dodge B200 and B300, 1981-1984 Dodge B150, B250, and B350, 1985-1994 Dodge B150, B250, and B350, 1995-1997 Dodge B1500, B2500, B3500, and 1995-1997 Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van. This Four Seasons 98636 heater core is also cross-referenced with APDI 9010141 for the same application.

What It Helps Repair

  • Weak or no heat from the HVAC system
  • Coolant odor inside the cabin
  • Fogging or film on the windshield caused by heater core leakage
  • Restricted coolant flow through the heater circuit
  • Leaking or corroded original heater core assemblies

Installation Notes and Tips

Verify front-position fitment and confirm the vehicle is a non-air-conditioning application before ordering. Compare the core dimensions and 0.625-inch tube size to the original unit, and inspect hoses, clamps, and coolant condition during replacement. Proper system bleeding after installation helps restore consistent heater performance.

Quality Assurance

This heater core meets or exceeds OEM specifications and is built in aluminum for HVAC service applications. Four Seasons 98636 is part of the Four Seasons Heater Core line, a focused product line for replacement heating components.
