Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant pressure tester, OBD-II scanner.
Safety Warnings: Allow the engine to cool before working on the cooling system. Wear gloves and eye protection.

2. Address Coolant Leaks

Sub-steps:
1. If leaks are found, replace damaged hoses or clamps.
2. If the radiator is leaking, remove it by unscrewing the mounting bolts and disconnecting the hoses.
3. Install the new radiator and refill with the appropriate coolant mixture (usually a 50/50 mix of antifreeze and distilled water).

3. Replace the Thermostat

Sub-steps:
1. Drain the coolant from the radiator.
2. Remove the thermostat housing by unscrewing the bolts.
3. Take out the old thermostat and replace it with a new one, ensuring the rubber gasket is in good condition.
4. Reattach the thermostat housing and refill the coolant.

4. Replace the Radiator Cap

Sub-steps:
1. Remove the old radiator cap by turning it counterclockwise.
2. Install a new radiator cap that meets OEM specifications.

5. Test Cooling Fans

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Observe the cooling fans to ensure they activate when the engine temperature rises.
3. If they do not, replace the cooling fan motor or check the associated relay and fuse.
