On a car as performance-based and powerful as Jaguar, any issues that arise can be a cause for alarm. With that in mind, there are many parts working together under the hood to bring about that power which you love so much. Any of these parts can have issues arise and, when they do, it is in your best interest to head to a professional shop to resolve them immediately.

Of the possible issues that may occur, thermostat housing failure is a serious problem that needs to be taken care of. Only trust a professional and never try to fix issues with the thermostat housing yourself, as the placement under the hood is tight. Without the proper experience, it’s possible you may simply do more damage than good.

What does the thermostat and thermostat housing do?

Your engine operates via numerous mini-explosions that fire the pistons within their cylinders. This action is converted into power and transmitted to the wheels where the impressive performance you love comes to light. However, none of this would be possible without your Jaguar’s thermostat and thermostat housing.

When those miniature explosions are going on under the hood, your engine gets extremely hot. In order to not overheat the engine, the thermostat of your Jaguar detects the temperature and releases a valve periodically which allows coolant to flow through the engine bay. This coolant absorbs the heat of the engine and transfers it to the radiator where it is cooled off by air entering from the grill.

From there, the coolant returns to its storage area until it is needed to cool off the engine again. Without the thermostat, there would be no way for the coolant to know when it should go to the engine and cool it off. The thermostat housing, however, is the part that actually allows the coolant to go through.

Your Jaguar’s thermostat detects the temperature of your engine and then tells the housing when to open and release coolant. If there is a problem with the thermostat housing, the valve may not open and no coolant will flow through the engine to cool it off, even if the thermostat itself is telling the housing unit to open.

Signs of a Failing Thermostat Housing

A problem with the thermostat housing is a serious issue that should be resolved as soon as possible. On that note, learning some of the common signs of a thermostat housing failure may be helpful to keep your Jaguar in the best shape possible. Stay vigilant for the below signs and take your car in if you happen to spot any of them:

High Engine Temperatures

There is a temperature gauge on the dashboard of your car which lets you know the temperature of your engine. For the most part, this dial shouldn’t move if the thermostat and housing unit are doing their jobs properly. If there is a problem, however, you may notice that your engine is overheating and the dial will reflect this by being in the red zone.

Coolant Leaks

Given that the thermostat housing holds back the coolant from entering the engine, you may notice a problem with the housing unit by seeing green coolant dripping onto your garage floor. Alternatively, check under your hood and see if any coolant has piled up around the thermostat housing.

Erratic Temperature

Similar to the high-temperature reading on your engine, check to see if the temperature of your engine is erratic. The valve in the housing unit may be fluctuating and allowing coolant to enter the engine when not necessary, but also not allowing it to enter. This will result in major temperature fluctuations reflected on the dial.
