Jaguars are luxury vehicles that set the standard of performance. Each make and model are uniquely designed for the simple and luxurious pleasure of driving. The engine under the hood is going to provide you with a powerful driving experience each time you get into the driver’s seat. This power is reflected by a beautiful style on the interior.
However, the longer you own your Jaguar, the greater the opportunity for maintenance and repairs. One part that may require attention is the thermostat housing. Below, you will find information about what this part is and how to look for signs when it begins to fail.
What is the thermostat housing?
In your Jaguar, the thermostat housing is a protective case that sits over the thermostat itself. The thermostat housing cover is also where the coolant circulates from the engine. The coolant travels through the opening and closing valve, which is situated as part of the thermostat housing protective cover.
The thermostat housing is also connected to the radiator via the radiator hoses. This means that it is in the optimal position to ensure that the coolant is continuously flowing as your Jaguar is running. With the connection to the thermostat housing, the radiator will always have access to the coolant, ensuring that engine component temperature is always cool. This part can usually be found near the engine block of your Jaguar but can vary depending on what make or model you have.
Symptoms and Signs of Thermostat Housing Failure
As stated above, the thermostat housing cover is an important piece in ensuring effective and optimal performance of your Jaguar. As your Jaguar ages, it is possible that the thermostat housing piece becomes damaged or begins to fail. Below you will find signs and symptoms that you should be aware of in order to catch the failure before it gets too bad.
1. High Temperature Reading and Engine Overheating
The high temperature reading will occur very quickly. It will signal into the red on the temperature gauge as quickly as 15 minutes after you turn your Jaguar on. This is the first sign that will indicate to you that the engine is not getting the proper amount of coolant. The valve attached to the thermostat is most likely stuck in a closed position. This will cause your engine to overheat very quickly and can cause serious damage if left unchecked.
2. Low Temperature Reading and Underheated Engine
Due to the fact that the thermostat housing contains an open and close valve, it could potentially get stuck in the open position. When this happens, the engine receives too much coolant and will operate at a lower temperature than it needs to. You will notice this because the temperature gauge on the dashboard will read very low. If this is not addressed, your Jaguar will not perform as efficiently as it should and will create a higher level of emissions.
3. Coolant Leaks
You will notice these leaks mainly around the thermostat housing. You will see it pooling all around the housing piece and also near the hoses that extend from it. If the leak is bad enough, then there will be spots indicating a leak under your Jaguar.
Servicing Your Jaguar
As your Jaguar gets older due to constant use, the possibility may arise where the thermostat housing piece needs to be repaired. If the piece gets damaged or needs to be inspected due to general wear and tear, you will be alerted to this by the signs and symptoms mentioned above.
