Solution

1. Preparation

Gather tools: socket set, screwdriver set, coolant pressure tester, shop towels, and safety glasses.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Hoses

Inspect: Check all coolant hoses for cracks or leaks.
Replace: If any hoses are damaged:
- Loosen the hose clamps using a screwdriver or socket.
- Remove the old hose and replace it with a new one, ensuring proper fit.
- Tighten the clamps to secure the new hose (torque to manufacturer specifications).

3. Repair or Replace the Radiator

Inspect: Check for any visible leaks in the radiator.
Repair: If minor leaks are found, use radiator sealant as a temporary fix.
Replace: If leaks are significant:
- Drain the coolant from the radiator via the drain plug.
- Disconnect any attached hoses and electrical connectors.
- Remove mounting brackets and lift the radiator out.
- Install the new radiator and reconnect hoses and connectors. Refill with coolant.

4. Check the Water Pump

Inspect: Look for leaks around the water pump weep hole.
Replace: If leaking:
- Drain the coolant from the system.
- Remove the drive belt and any components blocking access to the water pump.
- Unbolt the water pump and remove it from the engine.
- Clean the mounting surface and install the new water pump with a new gasket.
- Reassemble components and refill the coolant.

5. Test the Cooling System

Use a coolant pressure tester to pressurize the system and check for any leaks.
Ensure all replaced components are secure and there are no additional leaks.
