Replacement Expansion Tank Information
If you’ve ever stored a closed bottle of water in the freezer overnight, you know first-hand what happens when a volume expands in an enclosed space. Without room to grow, the edges of the vessel can burst open and leak – which is, quite frankly, rarely a good situation. In your vehicle, the key worry along these lines is the expansion of liquids and gasses in the vehicle that expand as temperatures rise and eventually run out of space as pressure soars. Internal combustion engines and their contributing parts rely on plenty of fluids and gasses in order to function – so the area beneath your car’s hood is home to a veritable city of substances, each of which can theoretically cause a problem. For this reason, the cooling systems of internal combustion engines include an expansion tank. This tank provides extra space for the antifreeze and air in the system to expand as necessary without causing any problems. If you need components to improve your expansion system, be sure to visit PartsGeek.com for great service and answers to all your questions.
