Compounding this, the composite thermostat housing becomes brittle from persistent thermal cycling in the compact \u003cstrong\u003eX204\u003c\/strong\u003e engine bay, risking sudden cracking and total pressure loss. Worn internal spring dampers inside the accessory belt tensioner also induce belt flutter, accelerating premature pulley failure and uneven belt wear across drive accessories.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service assembly delivers complete thermal and rotational reliability for your cooling system. Built with an upgraded internal bearing race and an OE-grade mechanical seal, the water pump assembly provides zero-cavitation fluid circulation through strict cylinder head passages. Paired with a direct-fit composite thermostat housing and calibrated thermostat, this kit maintains rigid coolant pressure and rapid operating temperature stability. Fresh hydraulic belt dampening and precision-machined pulleys eliminate drive-belt oscillation, restoring baseline factory harmonics.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Mechanical Water Pump Assembly\u003c\/li\u003e\n  \u003cli\u003e1 Water Pump Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Engine Coolant Thermostat Housing Assembly with Thermostat\u003c\/li\u003e\n  \u003cli\u003e1 Serpentine Belt Tensioner Assembly\u003c\/li\u003e\n  \u003cli\u003e1 Idler Pulley with Mounting Hardware\u003c\/li\u003e\n  \u003cli\u003e2 Serpentine Drive Belts\u003c\/li\u003e\n  \u003cli\u003e1 O-Ring\u003c\/li\u003e\n\u003c\/ul\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: solid font-size: min-width:\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;\"\u003e2013-2015 Mercedes Benz GLK-Class\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;\"\u003eM276 \/ X204\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;\"\u003e302 hp \/ 273 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;\"\u003e2762001301, 276200130180, 276200130187, US8173, 147-2360\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\u003e2013-2015 Mercedes Benz GLK-Class (GLK350) 3.5L V6 Gas Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the X204 GLK-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2013-2015 Mercedes Benz GLK-Class equipped with the \u003cstrong\u003eM276\u003c\/strong\u003e naturally aspirated 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs a complete cooling system vacuum-bleed required during installation?\u003c\/h4\u003e\n\u003cp\u003eYes, pulling a vacuum on the cooling circuit before refilling with factory-specified coolant is mandatory to prevent trapped air pockets in the internal engine blocks of modern direct-injected Mercedes engines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM tolerances, this kit maintains the tight tolerances and factory thermal thresholds of the Mercedes-Benz platform without causing erratic coolant temperature sensor readouts or diagnostic trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67923768738040,"sku":"DS-E4JBVDQWS","price":174.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-mercedes-benz-glk-class-2013-2015-3-5l-1.jpg?v=1793569132","url":"https:\/\/performancechiptuning.com\/products\/performance-water-pump-kit-for-mercedes-benz-glk-class-2013-2015-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
