There are several reasons why your Jaguar could have a thermostat housing failure. Each make and model of Jaguar is tailored to provide a sophisticated driving experience. However, the longer you own a Jaguar, the more possibilities for maintenance and repairs will arise. If you have used your Jaguar for quite some time, the thermostat housing is one component that may need to be replaced. In this article, you’ll learn what this part is and how to spot signs that it’s about to fail.
What is thermostat housing?
The thermostat housing in your Jaguar is a protective case that is found on the thermostat itself. This is why the coolant in your Jaguar circulates from the engine through the thermostat housing cover. The coolant passes through the entry and exit valves, which are part of the protective cover for the thermostat housing.
The radiator hoses also connect the thermostat housing to the radiator. This means it’s in the best possible position to keep the coolant flowing while your Jaguar is on the road. The radiator always has access to coolant thanks to the connection to the thermostat housing. This ensures that engine component temperatures are kept cool. The thermostat housing component is located close to the engine block of your vehicle, although this may vary depending on the model.
Symptoms of Thermostat Housing Failure
As previously stated, the thermostat housing cover is a component in Jaguars that ensures effective and optimal performance. It’s probable that the thermostat housing component on your Jaguar will become worn or fail as it ages. That is why you need to be aware of the symptoms listed below in order to detect the failure before it gets out of control.
- Engine Overheating and High-Temperature Readings: When your Jaguar’s thermostat starts failing, the temperature reading will be extremely high in a short period of time. It may take as little as 15 minutes for the temperature gauge to turn red after you turn on your Jaguar. This is the first indication that the engine is not receiving enough coolant. Most likely, the thermostat’s valve is stuck in the closed position. If left unchecked, it will cause the engine to overheat quickly and cause serious damage.
- Under-heated Engine and Low-Temperature Reading: Because the thermostat housing has an open and close valve, it may become stuck in the open position. Whenever this happens, the engine receives an excessive amount of coolant and operates at a lower temperature than it should. As a result of this, the dashboard temperature reading will be very low. Your Jaguar will not operate as efficiently as it should if this problem is not addressed, and it will emit more pollutants.
- Leaks in the Coolant System: These leaks are most noticeable around the thermostat housing. It will collect all around the housing piece, as well as near the hoses that protrude from it. There will be spots indicating a leak under your Jaguar if the leak is severe enough.
