Under constant expansion and contraction cycles, the factory molded polypropylene crystallizes and turns brittle. Stress fractures routinely develop along the sonic-welded horizontal assembly seam and around the inlet and return heater hose necks. These micro-cracks bleed off nominal system operating pressure (typically 21 psi), lowering the boiling point of the 50\/50 ethylene glycol mix, inducing localized coolant vaporization, persistent sweet fluid odors, and sudden loss of pressure head that risks severe cylinder head warpage on the \u003cstrong\u003eDuratec 25\u003c\/strong\u003e power unit.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to original equipment tolerances, this direct-fit pressurized degassing tank utilizes high-density, heat-stabilized virgin polymer resin formulated to withstand aggressive temperature swings without structural embrittlement. Precision-molded mounting tabs align with OEM chassis anchor points, while reinforced barbed hose necks resist fatigue from engine vibration and clamping loads. The translucent reservoir wall ensures immediate visual meniscus checks for rapid routine fleet inspections. Included is a freshly calibrated, spring-loaded OE-spec pressure cap that accurately regulates internal pressure and vacuum recovery, keeping your closed-loop cooling circuit completely sealed under peak fleet duty.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2014-2018 Ford Transit Connect\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eDuratec 25 (2.5L I4) \/ V408\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e169 hp \/ 171 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eCV6Z-8A080-C, CV61-8K218-BC, 603-278\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014 Ford Transit Connect (XL, XLT, Titanium) 2.5L I4\u003c\/li\u003e\n  \u003cli\u003e2015 Ford Transit Connect (XL, XLT, Titanium) 2.5L I4\u003c\/li\u003e\n  \u003cli\u003e2016 Ford Transit Connect (XL, XLT, Titanium) 2.5L I4\u003c\/li\u003e\n  \u003cli\u003e2017 Ford Transit Connect (XL, XLT, Titanium) 2.5L I4\u003c\/li\u003e\n  \u003cli\u003e2018 Ford Transit Connect (XL, XLT, Titanium) 2.5L I4\u003c\/li\u003e\n  \u003cli\u003eNote: Fits naturally aspirated 2.5L Duratec models only; does not fit 1.6L EcoBoost.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the V408 Transit Connect?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2014-2018 Ford Transit Connect equipped with the Duratec 25 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to replace the pressure cap when installing this reservoir?\u003c\/h4\u003e\n\u003cp\u003eA new, pre-calibrated pressure cap is already included with this unit to ensure system sealing pressure is completely refreshed.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Commercial Caliber\u003c\/h3\u003e\n\u003cp\u003eLight commercial fleet vehicles rely on thermal stability to maintain maximum uptime under severe stop-and-go delivery loads, and this replacement reservoir is designed to ensure factory-grade pressure retention to protect your work van from costly overheating downtime.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67524682350840,"sku":"DS-EDMVYVWC4","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/coolant-overflow-expansion-tank-for-ford-transit-connect-2014-2018-2-5l-1.webp?v=1790462867","url":"https:\/\/performancechiptuning.com\/products\/coolant-overflow-expansion-tank-for-ford-transit-connect-2014-2018-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
