Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery to prevent electrical issues during repairs.

2. Coolant Level Check and Refill

Tools Required: Coolant funnel
Check the coolant reservoir; if low, add the appropriate type of coolant (check owner's manual for specifications).
Inspect the radiator cap for damage and replace if necessary.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper, new thermostat, new gasket
Locate the thermostat housing; remove the bolts using a socket set.
Carefully detach the thermostat housing and remove the old thermostat.
Clean the mating surfaces with a gasket scraper to remove old gasket material.
Install the new thermostat and gasket, ensuring proper orientation.
Reattach the housing and torque bolts to manufacturer specifications.

4. Radiator Inspection and Replacement

Tools Required: Socket set, pliers, coolant funnel
Inspect the radiator for clogs or damage; if necessary, remove it by disconnecting the upper and lower hoses and mounting bolts.
Clean or replace the radiator as needed. If replacing, install the new radiator and reconnect hoses.
Refill the cooling system with the appropriate coolant mixture.

5. Radiator Fan Check

Tools Required: Multimeter, socket set
Test the radiator fan by connecting a multimeter to check for power.
If the fan does not operate, inspect the fan relay and replace if faulty.
If the fan is damaged, remove using a socket set, and install a new fan.
