1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the battery to avoid electrical issues.

2. Check and Replace Coolant

Tools Required: Coolant funnel, drain pan, and wrench set.
Drain old coolant from the radiator using the drain valve.
Flush the system with water to remove debris.
Refill with the appropriate coolant mixture (50/50 ethylene glycol and water).

3. Replace Thermostat

Tools Required: Socket set, torque wrench.
Remove the thermostat housing bolts.
Take out the old thermostat and replace it with a new one, ensuring the gasket is in place.
Reinstall the housing and torque to manufacturer specifications.

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, gasket scraper, torque wrench.
Remove the serpentine belt to access the water pump.
Unbolt the water pump from the engine and remove it.
Clean the mounting surface thoroughly.
