Cold weather start-ups often reveal slow leaks originating from this joint, which can be difficult to trace and progressively worsen with age. TGK Motorsport's solution replaces the OEM plastic part with a robust 6061-T6 billet aluminum elbow designed for long-term performance. Most importantly, it features a dual-gasket design that offers redundant sealing to eliminate coolant seepage and provide peace of mind — whether on a daily commute or under wide-open throttle. This is a must-have upgrade for anyone chasing down mystery coolant loss or proactively refreshing their 4.0T cooling system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tgk-section\"\u003e\n\u003cdiv class=\"tgk-sh\"\u003e\n\u003cdiv class=\"tgk-ic\"\u003e\u003csvg viewbox=\"0 0 24 24\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M3 3h18v2H3V3zm0 4h12v2H3V7zm0 4h18v2H3v-2zm0 4h12v2H3v-2zm0 4h18v2H3v-2z\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"tgk-sh-title\"\u003eSpecifications\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable class=\"tgk-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e6061-T6 Billet Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAngle\u003c\/td\u003e\n\u003ctd\u003e45 Degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSealing System\u003c\/td\u003e\n\u003ctd\u003eDual-Gasket Design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eAudi 4.0T Front Coolant System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation Instructions\u003c\/td\u003e\n\u003ctd\u003eAvailable Online\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tgk-section\"\u003e\n\u003cdiv class=\"tgk-sh\"\u003e\n\u003cdiv class=\"tgk-ic\"\u003e\u003csvg viewbox=\"0 0 24 24\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M13 2L3 14h9l-1 8 10-12h-9l1-8z\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"tgk-sh-title\"\u003eFeatures \u0026amp;
