It may seem like a simple part, but a poor seal quickly leads to air bubbles in the system and overheating. This OEM cap fits universally on standard expansion tanks and is essential maintenance for any air-cooled VW with a properly functioning cooling system. Combine this part with a new expansion tank or coolant hoses for a completely refreshed installation.\u003c\/p\u003e\n\u003cdiv style=\"background: #f9f9f6; border-left: 4px solid #2d6a35; border-radius: 4px; padding: 14px 18px; margin-bottom: 16px;\"\u003e\n\u003cdiv style=\"font-size: 0.75em; font-weight: bold; color: #2d6a35; text-transform: uppercase; letter-spacing: 0.06em; margin-bottom: 10px;\"\u003eFeatures\u003c\/div\u003e\n\u003cul style=\"list-style: none; padding: 0; margin: 0;\"\u003e\n\u003cli style=\"padding: 4px 0; font-size: 0.88em; color: #333;\"\u003e\n\u003cspan style=\"color: #2d6a35; margin-right: 8px; font-weight: bold;\"\u003e✓\u003c\/span\u003eOEM Reference 025 121 321\u003c\/li\u003e\n\u003cli style=\"padding: 4px 0; font-size: 0.88em; color: #333;\"\u003e\n\u003cspan style=\"color: #2d6a35; margin-right: 8px; font-weight: bold;\"\u003e✓\u003c\/span\u003eSuitable for Type 25, WBX until 04\/1983 and D until 01\/1984\u003c\/li\u003e\n\u003cli style=\"padding: 4px 0; font-size: 0.88em; color: #333;\"\u003e\n\u003cspan style=\"color: #2d6a35; margin-right: 8px; font-weight: bold;\"\u003e✓\u003c\/span\u003eUniversally applicable for air-cooled VW systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #fff; border: 1px solid #e0e0d8; border-radius: 4px; padding: 14px 18px; margin-bottom: 16px;\"\u003e\n\u003cdiv style=\"font-size: 0.75em; font-weight: bold; color: #555; text-transform: uppercase; letter-spacing: 0.06em; margin-bottom: 10px;\"\u003eTechnical specifications\u003c\/div\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-size: 0.88em;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"border-bottom: 1px solid #f0f0ea;\"\u003e\n\u003ctd style=\"padding: 6px 0; color: #777;\"\u003eYear of construction\u003c\/td\u003e\n\u003ctd style=\"padding: 6px 0; color: #1a1a1a; font-weight: 500;\"\u003eType 25, WBX -04\/83, D -01\/84\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom: 1px solid #f0f0ea;\"\u003e\n\u003ctd style=\"padding: 6px 0; color: #777;\"\u003eOEM comparison number\u003c\/td\u003e\n\u003ctd style=\"padding: 6px 0; color: #1a1a1a; font-weight: 500;\"\u003e025 121 321\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"BBT","offers":[{"title":"Default Title","offer_id":57293813481804,"sku":"4225-010","price":10.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/4678\/6124\/files\/4225-010.jpg?v=1777572164","url":"https:\/\/vintagedub.com\/products\/bbt-4225-010","provider":"VintageDub","version":"1.0","type":"link"}
