{"product_id":"engine-coolant-expansion-tank-13","title":"Engine Coolant Expansion Tank","description":"The Rein Automotive EPT0188 is an engine coolant expansion tank, also known as a coolant reservoir, that plays a crucial role in maintaining your vehicle's cooling system integrity. This component holds excess coolant, accommodating the natural expansion and contraction of the fluid as it heats up and cools down. Its strategic placement, often at the highest point in the system, facilitates the venting of trapped air while allowing for the addition of coolant without introducing air pockets. Detecting a faulty expansion tank is important, as a compromised unit can lead to cooling system overflows, a lowered coolant boiling point, and potential engine overheating. Signs of failure include steam or coolant leaks from the tank. A loose or faulty expansion tank cap can sometimes mimic expansion tank pressure issues, so checking the cap is a recommended first step. This Rein EPT0188 is designed as a direct replacement, ensuring OE quality and straightforward installation. It is compatible with select Porsche Cayenne and Volkswagen Touareg models, specifically the 2011-2018 Porsche Cayenne (including 3.6 V6 and 4.8 V8 engines) and the 2011-2017 Volkswagen Touareg (including Hybrid, TDI, TDI Executive, TDI Lux, and TDI R-Line trims).","brand":"Rein","offers":[{"title":"Default Title","offer_id":52663464395064,"sku":"EPT0188","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687612262.jpg?v=1784327147","url":"https:\/\/store.motormia.co\/products\/engine-coolant-expansion-tank-13","provider":"MOTORMIA","version":"1.0","type":"link"}
