Solution

1. Preparation

Tools Required: Socket set, coolant pressure tester, clean rags, funnel.
Allow the engine to cool completely before opening any components to avoid burns.

2. Identify and Repair Leak Source

A. Radiator Inspection
- Remove the radiator cap.
- Use a pressure tester to pressurize the system.
- Inspect for leaks from the radiator, and replace if necessary.
B. Hose Inspection
- Visually inspect all coolant hoses for cracks or loose clamps.
- Tighten or replace any damaged hoses.
C. Water Pump Inspection
- Check the water pump for leaks around the shaft.
- If leaking, remove the old water pump and install a new one.
- Torque the mounting bolts to the manufacturer's specifications.
D. Reservoir Inspection
- Check the coolant reservoir for cracks.
- If damaged, remove and replace with a new reservoir.

3. Refill and Bleed the Cooling System

Using a funnel, refill the cooling system with the appropriate type of coolant.
Bleed the system by running the engine with the radiator cap off until the thermostat opens and air bubbles escape.
