Toyota Camry Coolant Reservoir

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

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.

  • How to Keep Your Toyota Camry Coolant Reservoir in Prime Condition 27 February 2013

    Your Toyota Camry coolant reservoir is a highly needed part of your car's cooling system. However, due to the continuous flow of high-pressure coolant inside it, the coolant reservoir can also get damaged. To avoid coolant reservoir emergencies, here are some helpful maintenance tips:


    Top up your coolant regularly.


    Ensuring that your coolant is at the proper level is one of the most surefire ways of avoiding cooling system failure. Most coolant reservoirs need to be filled up to a third of its full capacity to have enough space for the extra coolant from your radiator. Check your car's service manual for the specific type of coolant to use and the correct coolant and water mixture.


    Test your coolant reservoir cap for the correct pressure.


    To avoid coolant overflow, test the efficiency of your coolant reservoir cap using a pressure tester. Check the correct amount of pounds per square inch (psi) that is marked on the reservoir cap and compare it to the reading you got from the pressure tester. If the coolant reservoir cap opens at a significantly lower pressure rating compared to the original specifications, then you have to replace the reservoir cap.


    Flush out your coolant mixture from time to time.


    Coolant mixture that has been left for several years on the reservoir will probably have accumulated dirt and is not delivering the best cooling performance for your car. Make sure to flush out the old coolant mixture at least once every two years to ensure that your cooling system stays in tiptop shape. Use a good radiator flush to clean out the tank and fill it up afterwards with the specific type of coolant for your vehicle.


    Replace damaged seals as soon as possible.


    To avoid coolant leaks resulting from worn-out seals, make sure to inspect the seals for signs of damage as part of your regular cooling system maintenance. If the seals have become too weak or too brittle, it's time to replace them.


    Visually check your coolant reservoir for damages.


    It is always a good idea to do a visual inspection on your coolant reservoir, especially during the really hot or really cold months. Extreme temperatures can weaken this plastic tank, so you should examine it from time to time to see if it has developed some cracks.
