• Disconnect the battery to ensure safety.

2. Replace Thermostat

• Remove the thermostat housing bolts using a socket set.
• Take off the thermostat housing and remove the old thermostat.
• Clean the mating surfaces to ensure a proper seal.
• Install the new thermostat (ensure the correct orientation) and reattach the housing with the bolts torqued to the manufacturer's specifications.

3. Repair or Replace Water Pump

• Drain the coolant from the radiator and remove the lower hose.
• Remove any components obstructing access to the water pump (e.g., belts, brackets).
• Remove the water pump bolts and pull the pump off the engine.
• Clean the mounting surface and install the new water pump, ensuring a new gasket is used.
• Reattach all components and hoses, refill coolant, and bleed the system to remove air pockets.
