BEST header overflow tanks PART DEALS MINIMUM EFFORT!

header overflow tanks


The header overflow tank in your car or van contains the coolant that has been forced from the vehicle's radiator under pressure and, as such, plays an important role and should be replaced if it is damaged. Here we will explain more about header overflow tanks.

Header overflow tank or expansion tank

The purpose of the vehicle's header overflow tank, or expansion tank, is to store the excess coolant and protect it. Essentially, it's a reservoir that is higher than the radiator to store the coolant overflow that's caused by expansion when the liquid reaches a high temperature. Without this header tank, the coolant would leak into the road when the coolant, which is a mix of water and antifreeze, is needed to help keep the car cool and prevent the engine from overheating. Most of the coolant that has been forced from the radiator into the expansion tank will later be returned to the radiator naturally when the engine is cool enough. It's this expansion tank that will catch the overspill of coolant and help circulate it around the engine.

Replace the header overflow tank

Issues you need to be aware of is if a leak appears in the cooling system, this may be in the expansion tank. For example, do you need to top up your coolant on a regular basis? If so, then there may be a leak and you'll need to replace the header overflow tank. But it's not just about keeping the car cool in summer, the coolant also helps keep the cabin warm in winter because the coolant will help prevent the engine from freezing up. Should there be a problem with the header overflow tank, then it may be a good idea to take your vehicle to a professional to have the problem diagnosed and for the issue to be repaired. Having a functional coolant system is important for the day-to-day working of your engine. If it is found that the header overflow tank doesn't have a leak, then you will need to check for a faulty radiator cap or the radiator itself as well as leaking hoses or a problem with the water pump. It may even be possible that coolant is being lost because of a cracked block or a blown head gasket. It may even be necessary to have the vehicle's radiator pressure tested to help work out where the leak is coming from.

It is important that the coolant system is checked on a regular basis and topped up when necessary, and not just in the summer months. This check should be carried out around the year to help prevent the engine block and the cylinder head from overheating and then fusing together. Since the engine will work harder in hot weather, it's important to maintain coolant levels and should you notice that the car is using more coolant than usual, then it's time to check for issues. It's also important to use the right coolant for this purpose.
