Inspect Radiator:
- Check for leaks or physical damage.
Replace Radiator (if needed):
- Remove the upper and lower radiator hoses using a hose clamp tool.
- Disconnect the transmission cooler lines if applicable.
- Remove any mounting bolts and carefully lift out the radiator.
- Install the new radiator and reattach all hoses and connections.

4. Replace Water Pump (if applicable)

Inspect Water Pump:
- Look for any coolant leaks around the water pump.
Replace Water Pump (if needed):
- Drain the coolant from the system.
- Remove the serpentine belt.
- Unscrew the water pump mounting bolts and remove the water pump.
- Clean the mounting surface and install the new water pump with a new gasket.
