data-path-to-node=\"2\"\u003eThis premium engine coolant regulator and thermostat housing assembly is manufactured to strict factory original equipment standards to manage thermal conditions within the engine core. Constructed from high-strength thermal-stable composite plastic, the integrated unit replaces the complete factory configuration, housing the dual-stage thermostat valve and precision sealing rings. It dynamically governs block-to-radiator tracking to warm the engine block quickly and avoid local hot spots under load. Replacing a brittle, leaking, or sticking factory housing prevents constant coolant loss, cabin heating failures, and catastrophic engine head warping from thermal overheating.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"3\"\u003eCompatible Vehicles\u003c\/h3\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003e\u003cspan class=\"citation-343 citation-end-343\"\u003eVolkswagen Polo 1.2 TSI (6R \/ 6C Platforms, 2009–2022)\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eVolkswagen Golf Mk6 \/ Mk7 1.2 TSI (2008–2016)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eVolkswagen Caddy 1.2 TSI (2010–2015)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eVolkswagen Jetta 1.2 TSI (2010–2018)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eVolkswagen Beetle 1.2 TSI (2011–2019)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eVolkswagen Touran 1.2 TSI (2010–2015)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eAudi A1 1.2 TFSI (2010–2018)\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\" id=\"p-rc_1b8c03cd47c4dfc6-119\"\u003eAudi A3 1.2 TFSI (2010–2013) \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cblockquote data-path-to-node=\"5\"\u003e\n\u003cp data-path-to-node=\"5,0\"\u003e\u003cb data-path-to-node=\"5,0\" data-index-in-node=\"0\"\u003eApplication Note:\u003c\/b\u003e Specifically engineered for Volkswagen Audi Group passenger models powered by the 4-cylinder 8-valve \u003cb data-path-to-node=\"5,0\" data-index-in-node=\"119\"\u003e1.2 TSI \/ TFSI\u003c\/b\u003e petrol engine family (Engine codes: CBZB, CBZC).
