Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the battery to prevent electrical shorts.

2. Identify the Leak Source

Perform a pressure test on the cooling system.
- Tools Required: Cooling system pressure tester
- Instructions:
  - Attach the pressure tester to the coolant reservoir cap.
  - Pump the tester to the manufacturer’s recommended pressure (usually around 15-20 psi).
  - Observe for drops in pressure or visible leaks.

3. Repair or Replace Faulty Components

A. Replace Coolant Hoses

Instructions:
- Use pliers to loosen and remove clamps from damaged hoses.
- Remove the hose and inspect fittings for damage.
- Install new hoses and secure with clamps, ensuring they are tight.
- Torque Value: Ensure clamps are snug but do not overtighten to avoid damaging hoses.

B. Replace Water Pump

Instructions:
- Drain coolant from the system.
- Remove the serpentine belt from the water pump.
- Unscrew and remove the water pump mounting bolts.
- Replace the old gasket with a new one and install the new water pump.
- Reinstall the mounting bolts and serpentine belt.
- Torque Value: Follow manufacturer specifications for water pump bolts.

C. Repair Radiator

Instructions:
- If the radiator is leaking, remove it by unscrewing mounting bolts and disconnecting hoses.
- If damage is minor, seal it with radiator stop leak; otherwise, replace it with a new unit.
- Install the new radiator and connect all hoses securely.

4. Refill Coolant

Instructions:
- Refill the cooling system with the manufacturer-recommended coolant type.
- Start the engine and allow it to reach operating temperature while checking for leaks.
