Is Your Jaguar’s Coolant Reservoir Failing? Know When to Get It Replaced

Is there a pool of coolant on the ground when you park your Jaguar? Has your engine been running very hot without any apparent reason? If so, then it is possible that your coolant reservoir is failing.

The coolant reservoir is a small but important component in your Jaguar’s cooling system. It provides additional coolant capacity and helps make sure that your engine runs at the optimum temperature. When it starts to fail, your engine can overheat, and this can cause a lot of damage. If the coolant reservoir is left unrepaired, it can lead to various engine problems, costly repairs, and even total engine breakdown. Here are some reasons why the coolant reservoir may fail, and why it is important to have it replaced as soon as possible.

What Causes Coolant Reservoir Failure?

• Cracks and Leaks: The coolant reservoir is made of plastic, which expands and contracts with changes in temperature. This repeated movement can lead to cracks in the plastic over time. If the reservoir cracks, coolant will begin to leak, and this leads to low coolant levels and overheating.
• Worn out Plastic: Jaguar coolant reservoirs are not meant to be permanent fixtures in your car, as they do wear out eventually. As time passes by, the plastic loses its strength and becomes fragile and brittle. If your Jaguar is a relatively older model, or has a high mileage, then the reservoir may have reached the end of its usefulness.
• Pressure Build-Up in the Cooling System: The reservoir helps allow coolant to circulate freely between the radiator and the engine. If there is a blockage or a problem with the pressure cap, however, there may be a build up of pressure in the reservoir, which can also cause cracks or even make the reservoir burst.
• Environmental Conditions: If you frequently drive in very hot or very cold temperatures, the coolant reservoir may deteriorate much faster. Extreme heat can cause the plastic to melt and bend while extreme cold makes the plastic brittle and easily breakable.

Why You Should Replace a Failing Coolant Reservoir Quickly

• Reduces the Chances of a Breakdown: A faulty coolant reservoir can lead to engine overheating, which can result in a major breakdown while driving. It is important to replace the reservoir if it is damaged to maintain the reliability of your Jaguar and prevent getting stranded on the road.
• Promotes Efficiency: A faulty coolant reservoir will cause fluctuation in the cooling system, which in turn hinders your Jaguar’s performance. Replacing it helps maintain the proper temperature in your engine, keeping your car running better for longer.
• Saving Money on Repairs: Failing to replace a faulty coolant reservoir might leave you with more serious issues, such as a blown head gasket or a damaged engine, and those repairs can cost up to thousands of dollars. It’s easy to see how replacing a coolant reservoir is a whole lot cheaper than allowing other engine parts to get damaged.

How Is the Coolant Reservoir Replaced?

First, a mechanic will examine the reservoir for cracks, leaks, or pressure-related problems that may cause poor performance of the engine. If a replacement is needed, old coolant will be drained to avoid any cross-contamination or spillage. After draining the coolant, the mechanic will then remove the damaged reservoir, unhooking all hoses and/or brackets before replacing it with a new one. They will then fill the system with new coolant and “bleed” it to get rid of any air bubbles. Last but not the least, the mechanic will inspect the system for any signs of leakage and perform a few tests to ensure that the engine runs at the expected temperature during operations.
