Mopar Heater Core

If there's coolant on the passenger side floor of your 2019-2026 Ram 2500/3500/4500/5500 truck (or 2019-2026 Ram 1500 - non-Classic) truck, or if the heat is not as warm as it should be, it's probably time to replace the heater core. Get this Mopar direct replacement part so it fits right the first time.

Replacing it is a big job, but a do-it-yourselfer with the time, tools and a service manual should be able to do it. Set a day aside and save a lot of money compared to having a shop do it for you. You'll find a number of videos on YouTube demonstrating how to replace the heater core if you want to have a look before attempting this job.

If you're replacing the dash in your truck, it's a good idea to go ahead and replace the heater core while you're in there. You won't want to do this job twice.

Compatability:

2019-2026 Ram 1500 (will NOT fit Ram 1500 Classic models)
2019-2026 Ram 2500/3500/4500/5500
