why does my Ram 1500 DT (2019-Present) lose coolant without any visible leaks?

Solution

1. Preparation

• Tools Required: Safety gloves, coolant pressure tester, combustion leak tester, oil dipstick, thermometer.
• Ensure the engine is cool before starting work to avoid burns or injuries.

2. Replace Head Gasket (if diagnosed)

• Sub-steps:
  1. Disconnect the battery.
  2. Drain the coolant from the system using a drain pan.
  3. Remove any components obstructing access to the cylinder head (intake manifold, exhaust manifold, etc.).
  4. Unbolt the cylinder head using a torque wrench, following the manufacturer's specifications.
  5. Remove the old head gasket and clean the mating surfaces thoroughly.
  6. Install the new head gasket, ensuring proper orientation.
  7. Reposition the cylinder head and torque the bolts to the specified values in the correct sequence.
  8. Reassemble the intake and exhaust manifolds, reconnecting all necessary components.
  9. Refill the cooling system with the appropriate coolant type.
  10. Reconnect the battery.

3. Replace Radiator Cap (if faulty)

• Sub-steps:
  1. Remove the old radiator cap by twisting it counterclockwise.
  2. Inspect the sealing surface for damage.
  3. Install the new radiator cap by pressing it down and twisting it clockwise until it clicks.
