Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Visual Inspection

Step 1: Open the hood and visually inspect the radiator, hoses, and coolant reservoir for cracks or damage.
Step 2: Look for any signs of coolant residue or stains around connections.
Tools Required: Flashlight (for better visibility).

3. Pressure Testing

Step 1: Connect the coolant pressure tester to the radiator cap opening.
Step 2: Pump the tester to apply pressure as specified in the pressure tester instructions.
Step 3: Observe the pressure gauge; if it drops, there is likely a leak.
Tools Required: Coolant pressure tester.

4. Dye Test (if necessary)

Step 1: Add UV dye into the coolant reservoir according to manufacturer instructions.
Step 2: Run the engine for 10-15 minutes to circulate the dye.
Step 3: Use a UV light to inspect for glowing areas, indicating a leak.
Tools Required: UV dye kit, UV flashlight.

5. Repair Any Identified Leaks

Step 1: Replace any damaged hoses or components identified during inspection.
Step 2: If a radiator leak is found, consider replacing the radiator.
Step 3: Replace any damaged gaskets or seals as necessary.
Parts Required: Replacement hoses, radiator, gaskets/seals, UV dye.
