Audi S5 Coolant Reservoir

The highly important defender of the engine's temperature stability is the Audi S5 Coolant Reservoir, which captures expanding fluid and returns it to the block when the coolant cools. The Coolant Reservoir is made of reinforced plastic at the peak of the system to seal out air and prevent rust and glycol from reaching the pavement. When shooting along in an S5, an increase in heat causes pressurized coolant to be pumped into the tank, and the clear MIN-MAX indicators allow drivers to check levels prior to the next blast. The engine cools down, causing the liquid to be drawn home without bubbles by vacuum, and the pump is not damaged, guaranteeing even distribution of heat in the cabin. There are two factory designs, a simple overflow design of the earlier years and a pressurized expansion tank with a rated metal tank cap that fits all modern S5s from the V8 originals to the current turbo V6. All versions can be easily swapped among coupes, Sportbacks, and Cabriolets while preserving factory warranties. The thick walls do not crack easily when temperatures vary between winter starts and extreme temperatures at track days as would be encountered by any Audi fan. Since the tank is part of a closed circuit, warning lights remain precise, which is economical and helps avoid damage to delicate turbo components in your Audi. One of the optimal features is the vividly shaped level graphics, which one can notice at a glance even in cloudy light, therefore the Coolant Reservoir assists new drivers in identifying problems before they grow out of proportion. By making this top original equipment selection, one adopts the same engineering mindset found in all Audi performance machines, where reliability is combined with a sense of luxury and the Coolant Reservoir will ensure an Audi stays cool, efficient, and safe.
