Cadillac Coolant Reservoir Cap maintains the cooling system as sealed and pressurized to prevent any damage to the fine power that makes Cadillac cars stand out of the traffic crowd. In 1902, Cadillac gained its fame due to a clean styling, powerful engines, and driving experience that makes it feel like skating on glass, and in the modern world, this energy is embodied in the comfortable cabins, bright displays, and a user-friendly driving interface that allows a teenager to pair a phone or toggle drive modes without searching in a menu. The brand even introduced the hand built Celestiq sedan complete with a smart glass roof and dash wide touchscreen to show that Cadillac continues to be ahead in integrating tradition with high technology and comfort that makes every errand a mini vacation. Coolant Reservoir Cap is a pressure rated lid that covers the expansion tank, maintains the pressure constant and coolant is allowed to expand back. The Coolant Reservoir Cap is simple to replace but do not forget to use some caution and make sure that the engine is completely cooled before you start the replacement process because safety first always and you do not want the trapped pressure to shoot down your face and give you a hissing nose so this is done by covering the old cap with a rag and pressing down on it and twisting it off so that the trapped pressure is released before you are caught in the middle of the hissing. Alternate the new Coolant Reservoir Cap with the old one, check the rubber seal, attach it and squeeze down and twist till it fits. To ensure a perfect install, fill up the coolant until the marked line, turn on the engine and observe it until the steady temperature and dry fittings.
