Solution

1. Regular Maintenance

Check Coolant Levels: Ensure coolant is at the appropriate level and topped off as necessary.
Flush Cooling System: Replace old coolant with manufacturer-recommended coolant every 30,000 miles or as specified in the owner’s manual.

2. Inspect and Replace Components

Thermostat Replacement:
- Remove the thermostat housing bolts using a socket set.
- Replace the old thermostat with a new one, ensuring it is the correct model for the 2019 Ram 1500 DT.
- Torque the housing bolts to manufacturer specifications (usually around 20 Nm).
Radiator Inspection:
- Visually inspect for any leaks or damage.
- If damaged, remove the radiator by disconnecting hoses and mounting bolts, then replace with a new radiator.

3. Enhance Cooling Efficiency

Upgrade to High-Performance Radiator Fan:
- Disconnect the battery.
- Remove the factory fan assembly by unscrewing the mounting bolts.
- Install a high-performance fan, ensuring correct alignment and secure fitting.
Install an Auxiliary Transmission Cooler:
- Locate a suitable space for the cooler in front of the radiator.
- Route lines from the transmission cooler to the new cooler, ensuring no kinks.
- Secure the cooler and connect the lines, tightening with a torque wrench to specified values.
