Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery if necessary.

2. Visual Inspection

Open the hood and visually inspect the engine compartment for any coolant residue.
Check around the radiator, hoses, and engine block for signs of leakage.

3. Check Coolant Reservoir

Remove the coolant reservoir cap carefully.
Inspect for cracks or leaks; if damaged, replace the reservoir.

4. Pressure Test

Attach the cooling system pressure tester to the coolant reservoir.
Pump the tester to apply pressure and observe for leaks.
If coolant escapes, identify the source and proceed with repairs.

5. Hose Replacement

If any hoses are found to be damaged, loosen the clamps and remove the affected hose.
Install the new hose, ensuring it is secured with clamps and properly routed.

6. Radiator Repair or Replacement

If the radiator leaks are found, drain the coolant and remove the radiator by disconnecting hoses and mounting brackets.
Replace with a new radiator, refill with coolant, and bleed the system.
