In order to understand the function of a coolant reservoir, it is necessary to first gain an understanding of how the whole cooling system works. When this happens, the cap of the tank will open, and the hot coolant would pop out like a puddle of lava. This system is made up of tubes and pipes that have coolant running through them.

DoItYourself.com®, founded in 1995, is the leading independent If an engine overheats and stays heated up for prolonged periods without the cooling, the head gasket blows up causing the oil to leak out into the coolant system. Hi everyone, I'm hoping that someone can describe how exactly the coolant reservoir on this car (2003 1.8T Quattro in my case) is supposed to work as I am experiencing a mysterious rapid loss of coolant after doing some major work on my vehicle: timing belt/water pump, head replacement (swapped my AMB with an AEB) and check valve simplification + removal of SAI pump system (AEB … Every vehicle I have owned (except this bimmer) has been pretty simple as far as the expansion tank goes. Questions of a Do It Yourself nature should be You can locate the reservoir by following the hose from the radiator. Latest. After this liquid passes back into the radiator, the reservoir will normally be left with only 1/3 of the coolant. When radiator pressure exceeds a point (determined by the cap spring) it allows coolant to pass to the expansion tank where it is available to be "sucked" back in when the pressure reverses. The radiator cap’s primary purpose is to maintain the coolant level and the reservoir pressure so that Coolant can travel at the usual rate around the hose. Your car’s cooling system works to extract heat from the engine and prevent this kind of damage. This excess coolant stays here until the system cools down enough to create negative pressure and draw the excess coolant from the reservoir back into circulation.

As coolant flows through the radiator, cool air blows past the radiator, cooling the coolant before it is recirculated through the engine. Why should you replace a damaged coolant reservoir? This helps to fill the engine with coolant. A coolant recovery/reservoir tank gives the system the ability to discharge and recharge coolant when needed to maintain the appropriate pressure. It works similar to an expansion tank on a water heater. While the engine is off, your coolant reservoir should be about 30% full.

How does this improvised coolant temp sender work? All information is provided "AS IS." Excess pressure is still vented from the engine at high working temperatures, but the expansion tank that it enters is more than simply a catchment reservoir: The coolant is drawn back into the engine by the vacuum created as temperatures decrease.
