Socket set
Screwdriver set
Pliers
Torque wrench
OBD-II scanner

2. Replace Thermostat (if faulty)

Locate the thermostat: Follow the upper radiator hose to the engine.
Drain coolant: Position a drain pan under the radiator, open the drain valve, and allow coolant to drain.
Remove components: Detach any components obstructing access to the thermostat (e.g., air intake, housing).
Remove thermostat: Unbolt the thermostat housing and extract the old thermostat.
Install new thermostat: Place the new thermostat in position, ensuring it is seated correctly.
Reassemble: Reattach the thermostat housing and any components removed.
Refill coolant: Use the appropriate coolant mix and refill the radiator and reservoir.

3. Repair or Replace Water Pump (if faulty)

Locate the water pump: Typically found at the front of the engine.
Remove drive belt: Loosen the tensioner and remove the serpentine belt.
Drain coolant: Position a drain pan and drain any remaining coolant.
Remove water pump: Unbolt the water pump from the engine block and detach it.
Install new water pump: Clean the mounting surface, apply gasket maker if needed, and install the new pump.
Reattach components: Reattach the drive belt and any other components removed.
Refill coolant: Refill the system with the correct coolant mixture.

4. Repair or Replace Radiator (if damaged)

Disconnect hoses: Detach the upper and lower radiator hoses from the radiator.
Remove the radiator: Unbolt it from its mounts and remove any mounting brackets.
Inspect for leaks: Check for cracks or corrosion; replace if necessary.
Install new radiator: Position the new radiator, secure it with bolts, and reconnect hoses.
Refill coolant: Refill the system with the appropriate coolant.
