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.
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.
