Solution

1. Preparation

Gather all necessary tools and safety equipment.
Ensure the engine is cool before starting.
Wear safety goggles and gloves for protection.

2. Visual Inspection

Sub-step 1: Open the hood and locate the coolant reservoir.
Sub-step 2: Inspect the reservoir for any visible cracks or leaks.
Sub-step 3: Examine all hoses connected to the radiator and engine for signs of wear, bulging, or leaks.
Sub-step 4: Check the radiator for any signs of corrosion or damage.

3. Pressure Testing

Sub-step 1: Remove the radiator cap using a radiator cap tool.
Sub-step 2: Attach the coolant pressure tester to the radiator neck securely.
Sub-step 3: Pump the tester to the specified pressure (typically around 15-20 psi, refer to the service manual).
Sub-step 4: Observe the gauge; if it drops, a leak is present. Inspect visually around the system while under pressure.

4. Water Pump Inspection

Sub-step 1: Locate the water pump, typically near the front of the engine.
Sub-step 2: Check the weep hole on the water pump for any signs of coolant leaking.
Sub-step 3: Inspect the pump gasket area for any coolant residue.

5. Final Checks

Sub-step 1: If leaks are found, mark the locations for repair.
Sub-step 2: If no leaks are found, replace the radiator cap and ensure all components are secure.
