2nd Gen Ram Heater Core (94-02) – 4720008

No heat in the cab — or a sweet coolant smell and foggy windshield that won’t clear. On 2nd Gen Ram trucks, a leaking or failed heater core is a common cause of both. The original Mopar part (4720008) has been discontinued. After evaluating multiple suppliers and consulting with our installers, we selected this aftermarket replacement as the best available direct-fit option.

Part Number: 4720008 (Mopar reference) | SKU: 4720008-HC4140

A note on sourcing: Ram Parts USA prioritizes genuine Mopar parts wherever possible. This part is an aftermarket replacement — the OEM has been discontinued and no US-made alternative is currently available. If you know of one, please contact our customer service team.
