Solution

1. Preparation

Gather tools: pressure tester, coolant, funnel, rags, and safety goggles.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Inspect and Repair Leaking Components

A. Coolant Reservoir

Remove the coolant reservoir cap.
Inspect for visible cracks or damage; replace if necessary.
Refill with the appropriate type of coolant.

B. Radiator Inspection

Visually check the radiator for corrosion or leaks.
If damaged, drain the coolant and remove the radiator using a socket set.
Replace with a new radiator, ensuring proper fit.

C. Hose Inspection

Trace all coolant hoses for signs of wear, bulging, or leaks.
Replace any damaged hoses using a hose clamp tool and ensure tight connections.

D. Water Pump Check

Inspect the water pump for coolant leakage from the weep hole.
If leaking, drain the system and remove the water pump with a wrench.
Install a new water pump, ensuring to torque bolts to manufacturer specifications.

3. System Pressure Test

Connect the pressure tester to the radiator filler neck.
Pump the tester to the specified pressure and monitor for leaks.
If leaks are detected, address them accordingly by replacing the faulty components.

4. Refill and Bleed the Cooling System

Refill the cooling system with the recommended coolant mixture.
Start the engine and let it reach operating temperature, allowing the thermostat to open.
Bleed any air from the system through the bleed valve (if equipped).
