Solution

1. Preparation

Tools Required: Socket set, screwdriver set, coolant recovery tank, OBD-II scanner
Allow the engine to cool completely before working on the cooling system to prevent burns.

2. Refill or Replace Coolant

Sub-steps:
1. Remove the radiator cap when the engine is cool.
2. Check the coolant level in the reservoir; add a 50/50 mix of coolant and distilled water if low.
3. If coolant is contaminated or old, drain the system and refill with fresh coolant.

3. Replace Thermostat (if faulty)

Sub-steps:
1. Drain the coolant from the radiator.
2. Disconnect the thermostat housing.
3. Remove the old thermostat and install a new one, ensuring proper alignment.
4. Reattach the thermostat housing and refill the coolant system.

4. Repair or Replace Leaking Components

Sub-steps:
1. Identify the source of any leaks found during inspection.
2. Replace any damaged hoses, seals, or the water pump as necessary.
3. Refill the coolant system after repairs are completed.

5. Test Cooling Fans

Sub-steps:
1. Check the fan relay and fuse for continuity.
2. If fans do not activate, replace the fan motor.
3. Ensure the fans are clear of debris and can spin freely.
