why does my Ram 1500 DT (2019-Present) have a coolant leak

Solution

1. Preparation

• Gather necessary tools and parts.
• Allow the engine to cool completely to prevent burns.
• Disconnect the battery to avoid electrical issues during repairs.

2. Inspect and Replace Hoses

• Tools Required: Hose clamp pliers, socket set, coolant catch pan
• Check all coolant hoses for damage.
• If any hoses are cracked or leaking, use hose clamp pliers to remove them from the fittings.
• Install new hoses by sliding them onto the fittings and securing them with hose clamps. Ensure the clamps are tightened to prevent leaks.

3. Repair or Replace the Water Pump

• Tools Required: Socket set, torque wrench, gasket scraper, coolant catch pan
• If the water pump is leaking, remove the serpentine belt by releasing tension on the tensioner.
• Disconnect any hoses connected to the water pump and remove the pump bolts.
• Carefully remove the water pump and scrape off any old gasket material from the mounting surface.
• Install the new water pump with a new gasket, tightening bolts to the manufacturer’s specified torque values.

4. Repair Radiator or Reservoir

• Tools Required: Socket set, coolant catch pan, radiator sealant (if applicable)
• Inspect the radiator and coolant reservoir for cracks. If damage is found, replace the component.
• If the leak is small, apply radiator sealant as an interim fix according to manufacturer instructions.

5. Refill and Bleed the Cooling System

• After repairs, refill the cooling system with the appropriate type of coolant as specified in the owner’s manual.
• Start the engine and let it reach operating temperature, checking for leaks.
• Bleed the cooling system to remove any air pockets by loosening the bleed valve (if equipped) while the engine is running.
