what should I do if my Honda CR-V Sixth Generation (2023-present) has a coolant leak

Solution

1. Preparation

• Gather tools and safety equipment.
• Ensure the engine is cool before starting work.
• Disconnect the battery to prevent electrical issues.

Tools Required:

• Socket set
• Screwdriver set
• Pliers
• Coolant pressure tester
• Drain pan

2. Addressing the Coolant Reservoir

• Step 1: Remove the coolant reservoir cap and drain any remaining coolant into a drain pan.
• Step 2: Detach the reservoir from the mounting bracket by unscrewing any fasteners.
• Step 3: Inspect the reservoir for cracks. If damaged, replace with a new unit.
• Step 4: If intact, clean it thoroughly before reinstallation.

3. Inspecting and Replacing Hoses

• Step 1: Locate and inspect the upper and lower radiator hoses. Look for bulges, cracks, or leaks.
• Step 2: If any hoses are damaged, use pliers to loosen the clamps and remove the old hoses.
• Step 3: Install new hoses, ensuring they fit snugly and reconnect the clamps securely.

4. Repairing or Replacing the Radiator

• Step 1: If leaks are found in the radiator, consider either repairing or replacing it.
• Step 2: To remove the radiator, drain the coolant completely and disconnect the upper and lower hoses.
• Step 3: Remove any mounting brackets and electrical connections.
• Step 4: Install the new radiator and reconnect all hoses and connections.

5. Checking the Engine Block and Heater Core

• Step 1: If leaks are suspected from the engine block, consult a professional for pressure testing.
• Step 2: For heater core issues, check for wet carpets inside the vehicle. If found, replace the heater core.
• Step 3: Disconnect the hoses leading to the heater core, remove the dashboard if necessary, and replace the heater core.

6. Refill and Bleed the Cooling System

• Step 1: Refill the cooling system with the recommended coolant type as per the owner's manual.
• Step 2: Start the engine and let it reach operating temperature while monitoring for leaks.
• Step 3: Bleed the system to remove any air pockets by running the engine with the radiator cap off until bubbles stop appearing.
