Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Check Coolant Level and Condition

Locate the coolant reservoir.
Remove the cap slowly to relieve any pressure.
Check the coolant level; if low, proceed to top-up or replace as necessary.
Inspect the coolant condition; if dirty or contaminated, consider a full flush.

3. Locate and Repair Leaks

Inspect hoses and connections for cracks or loose fittings.
Replace any damaged hoses with new parts.
If leaks are found at the water pump, replace the water pump and gasket as required.

4. Refill and Bleed the Cooling System

Use the recommended coolant type (check owner's manual).
Refill the coolant reservoir to the appropriate level.
Start the engine with the heater set to maximum to allow the coolant to circulate.
With the engine running, look for air bubbles in the reservoir; continue adding coolant until no more bubbles appear.

5. Final Checks

Reconnect the battery.
Start the vehicle and monitor the coolant temperature gauge.
Check for leaks around repaired areas after the engine has run for a while.
