Positioned inside the lower cooling flange or water pump housing, its primary operational function is to govern the volume of coolant circulating between the engine block and the radiator based on real-time operating temperatures. When the engine is cold, the thermostat remains securely shut, routing coolant through a tight bypass loop to ensure rapid warm-up, minimal component wear, and immediate cabin heating. Once the engine reaches its calibrated thermal threshold of 80°C, the internal wax capsule expands to open the valve, allowing hot fluid into the radiator. Over decades of driving, thermal cycling can stress the internal spring, causing the valve to stick open (resulting in an engine that runs too cold) or stick closed (inducing immediate, catastrophic engine overheating).\u003c\/p\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e MEYLE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e 028 280 0010 (AUTODOC ID: 8586303)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Number:\u003c\/strong\u003e MTH0022\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Condition:\u003c\/strong\u003e New\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Classification:\u003c\/strong\u003e Mechanical Coolant Thermostat Core\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpening Temperature [°C]:\u003c\/strong\u003e 80 (Engineered for early-opening thermal profiles)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Configuration:\u003c\/strong\u003e Without integrated housing (insert core only)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Components Included:\u003c\/strong\u003e\n    \u003cul\u003e\n      \u003cli\u003e1x 80°C Mechanical thermostat core unit\u003c\/li\u003e\n      \u003cli\u003e1x High-grade elastomeric sealing ring (O-ring)\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eVehicle Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis 80°C thermal valve configuration is precision-calibrated to match the cooling system pressures and flow rates of classic Volkswagen Audi Group (VAG) 4-cylinder and 5-cylinder passenger car lines from the early 1970s through the late 1990s:\u003c\/p\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth\u003eCar Model \/ Platform\u003c\/th\u003e\n      \u003cth\u003eCompatible Engines \u0026amp; Layouts\u003c\/th\u003e\n      \u003cth\u003eEngine Displacement Range\u003c\/th\u003e\n      \u003cth\u003eYear of Manufacture\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVW Golf Mk1 \u0026amp; Mk2 \/ Jetta Mk2 \/ Scirocco \/ Corrado\u003c\/td\u003e\n      \u003ctd\u003e1.5 \/ 1.6 \/ 1.8 Petrol \u0026amp; 1.6 D \/ 1.6 TD Diesel lines \u003cbr\u003e\u003cem\u003e(Famous codes: DX, EV, PB, RP, GU, KR, SB, JR)\u003c\/em\u003e\n\u003c\/td\u003e\n      \u003ctd\u003e1457 - 1781 cc\u003c\/td\u003e\n      \u003ctd\u003e1974 - 1992\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAudi 80 \u0026amp; 90 (B2, B3, B4) \/ Coupe \/ Cabriolet\u003c\/td\u003e\n      \u003ctd\u003e1.6 \/ 1.8 \/ 2.0 4-Cyl \u0026amp; 2.2 \/ 2.3 5-Cylinder Petrol engines\u003c\/td\u003e\n      \u003ctd\u003e1595 - 2309 cc\u003c\/td\u003e\n      \u003ctd\u003e1978 - 1996\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVW Passat B2, B3 \u0026amp; B4 (32B, 35I, 3A2)\u003c\/td\u003e\n      \u003ctd\u003e1.6 \/ 1.8 \/ 2.0 Petrol and early 1.6\/1.9 Diesel variants\u003c\/td\u003e\n      \u003ctd\u003e1595 - 1984 cc\u003c\/td\u003e\n      \u003ctd\u003e1980 - 1997\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAudi 100 (C3, C4) \/ A6 C4 Saloon \u0026amp; Avant\u003c\/td\u003e\n      \u003ctd\u003e1.8 \/ 2.0 4-Cyl and classic 2.3L 5-Cyl (AAR) engine layouts\u003c\/td\u003e\n      \u003ctd\u003e1781 - 2309 cc\u003c\/td\u003e\n      \u003ctd\u003e1982 - 1997\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cblockquote\u003e⚠️ \u003cstrong\u003eOpening Temperature Specification Notice:\u003c\/strong\u003e This thermostat features an \u003cstrong\u003e80°C opening threshold\u003c\/strong\u003e, which opens earlier than standard 87°C or 92°C variants. This configuration is widely favored in classic high-performance setups (like modified GTI or 5-cylinder engines) or warmer climates to build a safer thermal overhead and keep operating pressures stable. When overhauling the cooling loop, never re-use the old O-ring. Thoroughly scrape away calcium deposits from the plastic or aluminum water outlet flange before installation to prevent slow, nagging coolant leaks under pressure.\u003c\/blockquote\u003e\n\n\u003ch3\u003eOriginal Equipment Manufacturer (OEM) Reference Numbers\u003c\/h3\u003e\n\u003cp\u003eThis premium replacement coolant valve cross-references directly with, or serves as a factory-correct swap for, the following original factory catalog codes and premium aftermarket listings:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVAG (VW \/ AUDI \/ SEAT \/ SKODA):\u003c\/strong\u003e 044121113, 056121113D, 068121113, 068121113H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFEBI BILSTEIN (Interchange Reference):\u003c\/strong\u003e 01198, 1198\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGATES (Interchange Reference):\u003c\/strong\u003e TH03380G1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHELLA (Interchange Reference):\u003c\/strong\u003e 8MT 354 774-011, 8MT354774011\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVALEO (Interchange Reference):\u003c\/strong\u003e 820168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"meyle","offers":[{"title":"Default Title","offer_id":57537979449727,"sku":"028 280 0010","price":19.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1005\/7252\/9023\/files\/preview_2a256a27-8d5a-45a7-926d-a6900099da20.jpg?v=1778859344","url":"https:\/\/klassik357.eu\/products\/vw-thermostat-028-280-0010","provider":"Klassik357 - Classic and retro car parts","version":"1.0","type":"link"}
