Replacing a faulty thermostat housing is crucial for maintaining the efficiency of your vehicle's cooling system. This guide also includes a list of necessary parts to ensure a smooth replacement process.

Step 1: Gather Necessary Tools and Parts

Before starting the replacement, make sure you have all the required tools and parts. Here’s what you will need:

• Parts:

  • AC Delco Throttle Body Heater Inlet Hose (part # 25192905)
  • AC Delco Engine Oil Cooler Seal (part # 25194222)
  • Dorman Aluminum Thermostat Housing (part # 902-003)
  • AC Delco OEM Thermostat Housing (part # 15-81816)

• Tools:

  • Coolant Hose Clamp Pliers Set
  • Basic hand tools (screwdrivers, wrenches, etc.)
  • Safety glasses and gloves

Step 2: Prepare the Vehicle

1. Safety First: Ensure the engine is cool, and disconnect the negative battery terminal to prevent any electrical issues.
2. Drain Coolant: Place a drain pan under the radiator and open the drain valve to remove the coolant. This will prevent spills during the housing replacement.

Step 3: Remove the Old Thermostat Housing

1. Access the Housing: Locate the thermostat housing, which is typically at the engine's front, near the throttle body.
2. Disconnect Hoses: Use the coolant hose clamp pliers to loosen and remove any hoses connected to the thermostat housing.
3. Unbolt the Housing: Remove the bolts securing the thermostat housing using the appropriate socket or wrench. Keep track of the bolts for reinstallation.
4. Remove the Housing: Carefully lift the old thermostat housing from its place. Inspect the old gasket and clean any residue from the engine surface.

Step 4: Install the New Thermostat Housing

1. Prepare New Gasket: Place a new gasket on the engine surface where the thermostat housing will sit.
2. Position the New Housing: Align the new thermostat housing over the gasket and ensure it fits snugly.
3. Bolt in Place: Reinsert the bolts you previously removed and tighten them to the manufacturer's specifications. Be careful not to overtighten, as this can damage the housing.

Step 5: Reconnect Hoses and Refill Coolant

1. Reconnect Hoses: Reattach all hoses to the new thermostat housing, ensuring they are secure and properly clamped.
2. Refill Coolant: Close the radiator drain valve and refill the coolant through the reservoir. Check for any leaks around the new housing and hoses.
3. Reconnect Battery: Reattach the negative battery terminal to restore power to the vehicle.

Step 6: Test the System

1. Start the Engine: Turn on the engine and let it idle. Monitor the temperature gauge to ensure the engine does not overheat.
2. Check for Leaks: After the engine reaches operating temperature, inspect the thermostat housing and hose connections for coolant leaks.
3. Take a Test Drive: Drive the vehicle for a short distance to ensure everything is functioning correctly.

Conclusion

Replacing the thermostat housing on a 2014 Chevy Cruze is a manageable task with the right preparation and tools. By following these steps, you can ensure your vehicle’s cooling system operates efficiently. If you experience any issues or leaks after the installation, revisit the connections and tighten as necessary. Regular maintenance of your vehicle’s cooling system can prolong its life and performance.
