Hi there,
Yes. By replacing the thermostat gasket, the leak can be fixed. The seal sits between the thermostat housing and the engine block. It usually wears out over time. You can easily replace the gasket with going to a repair shop. Here are simple steps to do it:
1. Drain the coolant from the engine.
2. Unbolt/remove the thermostat housing (check DIY videos online for that procedure).
3. Remove worn-out thermostat seal/gsket.
4. Put the new gasket to the thermostat and reinstall the thermostat.
5. Tighten the mounting bolts to the correct torque specifications.
6. Refill the radiator with coolant.
I hope this helps!

If you have a coolant leak coming from the area around the thermostat housing on a 2009 Crown Victoria, the cause could be one of several things, and determining the exact source of the leak is crucial.
Thermostat Gasket/Seal: It's very possible for the gasket or seal of the thermostat housing to deteriorate over time, leading to a coolant leak. If the leak appears to be coming directly from the seam between the thermostat housing and the intake manifold or engine, the gasket/seal is a likely culprit.
Solution: Replacing the thermostat and its gasket/seal might resolve the issue. This is a relatively straightforward and inexpensive repair.
Thermostat Housing Cracks: The thermostat housing itself, especially if it's made of plastic, can develop cracks over time. Temperature fluctuations, age, and material stress can contribute to this.
Solution: If the housing is cracked, it will need to be replaced.
Intake Manifold: On certain Ford models, including some Crown Victorias, the intake manifold (especially if it's the plastic version) has been known to develop cracks or become warped over time, leading to coolant leaks. If the leak is near the thermostat housing but not directly from it, the intake manifold could be the source.
Solution: If the intake manifold is leaking, it will typically require replacement. This is a more involved and costlier repair than just the thermostat housing.
Other Nearby Components: Sometimes, a leak can originate from a nearby component and then drip down, making it look like it's coming from the thermostat housing area. Coolant hoses, hose clamps, and other nearby components should also be checked.
Solution: Replace or tighten the offending component.
To determine the exact cause:
Clean the Area: Wipe down the area where you see the coolant to get a better view of the origin of the leak.
Pressure Test: Performing a cooling system pressure test can help identify the source of the leak. By pressurizing the system, you can force coolant out of the leak source, making it easier to spot.
Considering the symptoms you've described, I'd recommend starting by inspecting the thermostat housing and gasket/seal. If they're in poor condition, replace them. If the issue persists or if you find the leak is coming from the intake manifold or another component, address it accordingly. Given the potential for overheating or engine damage from prolonged coolant leaks, it's essential to address the issue promptly.
