Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Coolant

Tools Required: Coolant container, funnel, gloves
Sub-steps:
1. Open the coolant reservoir cap slowly to release any pressure.
2. Drain the coolant from the radiator into a container.
3. Check for contamination or debris in the old coolant.
4. Refill the radiator and reservoir with manufacturer-approved coolant.

3. Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper
Sub-steps:
1. Locate the thermostat housing and remove the bolts holding it in place.
2. Remove the old thermostat and clean the mating surfaces.
3. Install the new thermostat with the correct orientation.
4. Reattach the housing and torque bolts to manufacturer specifications.

4. Check and Replace Water Pump (if necessary)

Tools Required: Socket set, gasket scraper, coolant container
Sub-steps:
1. Remove any components obstructing access to the water pump (e.g., belts).
2. Remove the water pump by unscrewing the mounting bolts.
3. Clean the mounting surface on the engine block.
4. Install the new water pump and ensure it is properly aligned.
5. Reattach any removed components and belts.

5. Verify Radiator Fan Operation

Tools Required: Multimeter
Sub-steps:
