Reasons behind Usual Toyota Camry Coolant Reservoir Problems
Your Toyota Camry coolant reservoir is a component that is used to high-temperature and high-pressure operation. However, this piece of tough plastic can still suffer from damage that lead to some serious overheating problems. If your car has been heating up much faster than usual and your cooling system is working much less efficiently, then you might want to take a look at your coolant reservoir. Here are some of the most common issues of a defective Toyota Camry coolant reservoir:
Constantly low coolant level
If you have been consistently topping up the coolant on your radiator and coolant reservoir only to find out that you are running low on coolant again, you most likely have a leak somewhere in your cooling system. If your hoses and radiator are intact, check your coolant reservoir for any cracks or look beneath your vehicle for puddles or droplets of coolant. If you can't find the source of the leak, you can take your coolant reservoir to a mechanic for a pressure test. Some coolant reservoirs have visually undetectable cracks that are responsible for the leaking coolant.
Overheating is a very common symptom of cooling system failure. After ruling out all the other components in your cooling system, check your coolant reservoir for signs of a faulty coolant reservoir cap. A coolant reservoir cap that doesn't hold enough pressure can lead to your coolant boiling and overflowing. If you can find coolant deposits around the coolant reservoir cap, or if you hear a sort of hissing sound from this component, then it's time to replace the cap.
Other troubleshooting techniques
When you take a look under your hood to examine the coolant reservoir, make sure that you also take note of any sort of damage to other parts of the coolant system. Many car owners have unnecessarily replaced the coolant reservoir just to find out that the faulty component is actually one of the hoses or the radiator cap. It is also important to check the quality of all the seals and fittings around the hoses from your coolant reservoir to the radiator, since worn-out seals and fittings can also cause leaks.
