Ford Taurus Expansion Tank

Ford Taurus Expansion Tank: Common Problems and Simple Ways to Solve Them

If there's one part that your Ford Taurus can't function without, then it's the expansion tank. Located in the cooling system, this part prevents problems by allowing excess coolant to drain into it whenever the pressure in the radiator reaches high levels. However, due to constant use, this tank eventually gets damaged. Listed below are some common problems that you may encounter with a faulty expansion tank.

Stained expansion tank

Over time, the expansion tank of your Ford Taurus will become stained due to the contaminants and other kinds of road debris that get caught up in the coolant stream. Though these yellowish stains may seem easy to remove, they may prove otherwise especially if they have been there for some time. Nonetheless, if you really want to restore your expansion tank, then you need to prepare a calcium-lime-rust remover and bleach. However, make sure that you will not heat up the CLR remover in an enclosed area because the fumes that it will produce will make you sick. Also, allow it and the bleach to sit inside the tank for a few hours for best results.

Coolant leaks

Although your Ford Taurus expansion tank is designed to last for a long time, it may still get damaged due to constant exposure to the varying temperatures in the engine block. Once this happens, coolant may start to leak and cause your vehicle to overheat. To solve this problem, you can try using an automotive epoxy product. However, because this will not last for a long time, you'd better purchase a new expansion tank from an auto parts store to replace the damaged one.

Expansion tank bubbles

Seeing some bubbles in your expansion tank is very common especially because one of the functions of this part is to remove cooling system bubbles. However, if the bubbles are in the coolant, then you'd better check the head gasket for signs of damage. To do this, you need to use a cylinder leakage tester to check each cylinder for leaks. If there are bubbles, then you need to replace the head gasket immediately to avoid causing further damage to the expansion tank.

  • Tips to Get the Most Out of Your Ford Taurus Expansion Tank

    Also known as the overflow tank, your Ford Taurus' expansion tank is a very important part in the cooling system. Typically made from high-quality plastic, this tank is designed to keep your vehicle's excess coolant. However, if not taken care of properly, it will eventually get damaged and cause various problems. To avoid these catastrophes, just follow the simple maintenance tips that we listed below.

    Clean your Ford Taurus expansion tank routinely.

    One way to make sure that your expansion tank will last for a long time is by cleaning it routinely. Fortunately, this can be done at home using a rag, old toothbrush, and bleach mixture. However, make sure that you will allow the engine to cool for a few minutes before doing this to avoid getting scalded by hot coolant.

    Check the expansion tank for stains.

    After some time, the expansion tank of your Ford Taurus will become stained due to various factors. Once this happens, you will not be able to measure your vehicle's coolant level well. To prevent this, you must check the tank for stains and rust routinely. In case you find any, you can try using a calcium-lime-rust remover that can be bought from an auto parts store. Just make sure that you will not heat this substance in an unventilated room to avoid accidents.

    Inspect your vehicle's expansion tank for leaks regularly.

    Another way to get the most out of your expansion tank is by inspecting it regularly for leaks. Usually, because of exposure to high temperatures in the engine block, this tank becomes warped or damaged. As a result, your Taurus may overheat because of coolant leaks. Thus, don't forget to visually inspect the expansion tank before taking your vehicle for a drive.

    Make sure that there are no bubbles in the expansion tank.

    Although seeing a few bubbles in your Ford Taurus expansion tank if the engine is not overheating is normal, seeing them in the coolant can indicate something else. Usually pointing to a faulty head gasket, this problem should not be ignored to avoid damaging the expansion tank and other engine components.
