Is your engine temperature rising higher than normal, or have you noticed coolant leak on the ground? If your answer is yes, then your Jaguar may have a faulty coolant reservoir.
The coolant reservoir is a tank that holds extra coolant and regulates the pressure in the cooling system of your Jaguar. When the engine is hot, the coolant increases in volume and the excess fluid moves into the reservoir. Once the engine is cold, the coolant is drawn back into the system. The reservoir is commonly made of plastic and is installed close to the engine compartment. It is attached to the radiator and other components of the cooling system through hoses.
When it cracks, leaks, or stops holding pressure, the engine of your Jaguar can overheat. Whether you own a luxury car like Jaguar or any other brand, the smallest leak or crack in the coolant system can lead to a big problem in the engine if not taken care of. Let’s look at how the coolant reservoir functions, common issues that can occur, and how to go about changing a faulty reservoir.
How to Fix a Failed Coolant Reservoir
- Check the Cooling System Properly: It is important to know the root of the problem before jumping to replace any part of the cooling system. Although a cracked or leaking water reservoir is one of the most probable causes, other issues such as a bad radiator cap or worn-out coolant hoses may present similar signs. A thorough physical examination, sometimes accompanied by a pressure test, can effectively determine if the coolant reservoir is the culprit.
- Drain the Coolant Safely: After the cause of the problem is established, the next thing to do is to drain the coolant from the car. This prevents coolant from spilling all over other parts of the engine. Draining is mostly carried out with the help of the radiator drain valve or any other port designed for the system, and the old liquid is either disposed or reused after being collected in a clean container.
- Remove the Faulty Coolant Reservoir: The faulty reservoir is then removed from the assembly. This entails detaching any hoses connected to it, disconnecting any sensors that may be connected to the reservoir and unscrewing the reservoir from the bracket on which it sits. Since there is limited space in some Jaguar models, caution and proper tools are required to avoid damage to surrounding components.
- Replace the Old Reservoir: After disassembling the old unit, a new OEM or high-quality aftermarket reservoir is put in place. When looking for the new part it is important that you consider the specifications of your Jaguar so that you are sure that the part will fit and work properly. All hoses and connections are fixed and any integrated sensors are reconnected back in place.
What Happens If You Ignore It?
It is dangerous to drive a Jaguar with a faulty coolant reservoir. Lack of proper coolant levels and system pressure can cause the engine to overheat. This can cause the cylinder heads to become distorted, the head gaskets to blow, and other costly problems to arise. Also, coolant is toxic. Leakages are not only disastrous to your engine, but also pose a threat to the lives of our domesticated animals as well as the environment. Taking care of a reservoir problem right from the start is always better than waiting for it to worsen.
