2021+ Ram TRX Heating and Cooling Parts

Radiators, HVAC and cooling system parts for the 2021-2023 Dodge Ram 1500 TRX 6.2L supercharged Hemi truck.

Don't forget to replace your in-cabin air filter every year - if your truck smells a little used inside, replacing that filter can help.

The Mopar 68163849AB antifreeze/coolant is recommended for the TRX. This coolant is a pink/purple color and it does change color slightly due to temperature. So if your supercharger overflow is a different hue than your engine coolant, that's ok. Just make sure your levels don't drop under the minimum.
