how to check for coolant leaks in my Honda CR-V Sixth Generation (2023-present)

Solution

1. Preparation

• Gather tools and materials: coolant pressure tester, UV dye kit, UV light, clean rags, and safety gloves.
• Ensure the engine is cool to prevent burns. Disconnect the battery if necessary.

2. Visual Inspection

• Inspect the coolant reservoir for cracks or leaks. If damaged, replace it.
• Check the radiator and surrounding areas for visible coolant leaks or damage.

3. Hose and Clamp Inspection

• Examine all hoses leading to and from the radiator for cracks, bulges, or leaks.
• Tighten any loose clamps and replace damaged hoses as needed.

4. Water Pump Inspection

• Look for signs of coolant leakage around the water pump area. If leaking, replace the water pump.
• Check the weep hole (if equipped) for signs of coolant escaping, indicating a failing pump.

5. Dye Test

• Add UV dye to the coolant reservoir and run the engine for a short period.
• Use a UV light to inspect the engine bay for any glowing signs indicating a leak.

6. Pressure Testing

• Connect the coolant pressure tester to the radiator cap opening.
• Pump the tester to the recommended pressure (usually around 15 psi) and monitor for pressure loss.
• Identify and repair any leaks found during the pressure test.
