{"product_id":"mishimoto-2019-ram-6-7l-cummins-aluminum-expansion-tank-black","title":"Mishimoto 2019+ Ram 6.7L Cummins Aluminum Expansion Tank - Black","description":"The factory expansion tank on your 2019+ Ram 6.7L Cummins is a weak point in an otherwise durable cooling system. Made from plastic, the stock tank becomes brittle over time and is prone to cracking, discoloration, and internal degradation after thousands of heat cycles. Mishimoto's aluminum expansion tank is built to solve that problem before it starts. Its TIG-welded construction holds up under high temperatures and heavy use, while internal baffles prevent coolant starvation and reduce the risk of air pockets that can harm engine cooling.--To make installation simple, this expansion tank fits directly in place of the factory unit and does not require draining the entire cooling system. No specialty tools are needed, and all necessary provisions for factory sensors are included. That includes an OEM-style level sensor that allows the truck's stock low coolant warning system to function exactly as intended.--Beyond durability and ease of install, this expansion tank gives your engine bay a cleaner, more finished look. The Mishimoto expansion tank is available in either micro-wrinkle black or a natural finish, for easy customization through powder-coating, anodizing, or hydro-dipping. It replaces the aging plastic tank with something built to last and designed to look good doing it.--Like all of our products, this expansion tank is backed by the Mishimoto Lifetime Warranty.\nEngine coolant reservoir designed to store and regulate excess coolant for proper system operation.

Constructed from TIG-welded aluminum, this durable reservoir offers superior resistance to high temperatures and pressure compared to the factory plastic tank, which can become brittle, crack, or discolor over time due to thermal cycling. Its robust design ensures long-lasting performance, helping to prevent coolant leaks and maintain optimal engine temperature during heavy use or demanding conditions. The internal baffles are engineered to stabilize coolant flow, reducing the risk of air pockets that can lead to inefficient cooling or engine overheating. \u003cbr\u003eInstallation is straightforward as this expansion tank replaces the OEM unit directly without the need to drain the entire cooling system. All necessary provisions for factory sensors are included, including an OEM-style level sensor that preserves the truck’s low coolant warning system. This feature ensures safety and peace of mind, allowing the vehicle’s onboard diagnostics to function as originally intended. \u003cbr\u003eBeyond its functional advantages, this Mishimoto expansion tank enhances the appearance of your engine bay with a sleek, finished look. It is available in a micro-wrinkle black finish or a natural aluminum surface, offering options for customization through powder coating, anodizing, or hydro-dipping. This upgrade not only improves durability but also adds a clean, professional aesthetic to your engine compartment. Backed by Mishimoto's Lifetime Warranty, this component provides a reliable, long-term solution for maintaining coolant levels and system integrity in your Ram diesel truck.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eTIG-welded aluminum construction for durability and heat resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInternal baffles help maintain coolant stability and prevent air pockets\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes OEM-quality level sensor to preserve low coolant warning system functionality\u003c\/li\u003e\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":53602464268561,"sku":"MMRT-RAM-19BK","price":559.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/3c3354aa85c19f40285e16b560bb373dL.jpg?v=1779944031","url":"https:\/\/shoprenegade.com\/products\/mishimoto-2019-ram-6-7l-cummins-aluminum-expansion-tank-black","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
