Inspect Radiator:
- Look for signs of damage, corrosion, or leaks.
Replace Radiator (if necessary):
- Drain the coolant using a drain pan.
- Disconnect upper and lower radiator hoses and cooling fan electrical connectors.
- Remove mounting bolts and lift the radiator out.
- Install the new radiator, reattach hoses, and torque the bolts as per specifications.

4. Inspect and Replace Water Pump

Inspect Water Pump:
- Check for leaks around the water pump and listen for unusual noises.
Replace Water Pump (if necessary):
- Drain the coolant system.
- Remove the serpentine belt.
- Disconnect the water pump from the engine block, removing bolts and any coolant hoses.
- Install the new water pump, ensuring the gasket is properly seated.
- Torque bolts to specifications (usually around 18-25 ft-lbs) and reattach hoses.
