The confirmed applications below identify an original engine cooling assembly fastening position on the TTS with the CDMA engine and the listed front-wheel-drive TT auxiliary coolant-pump bracket.

Follow the relevant component removal procedure and inspect the mating mounting surfaces and receiving threads. Start the bolt without cross-threading, seat the attached component in its original position and follow the factory tightening sequence for that attachment.\u003c\/p\u003e\u003cp\u003eUse the specified torque and any required thread treatment from the repair procedure; neither is established solely by the bolt diameter. If cooling components are removed, complete the prescribed refilling, bleeding and leak checks as part of the repair. Verify the repaired mounting connection is securely seated before returning the vehicle to service.\u003c\/p\u003e","brand":"Genuine VW\/Audi","offers":[{"title":"Default Title","offer_id":48014380564657,"sku":"N-014-721-8","price":4.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/1379\/3201\/files\/n-014-721-8-genuine-vw-audi-1.jpg?v=1791602660","url":"https:\/\/hstuning.com\/products\/n-014-721-8-genuine-vw-audi-socket-head-bolt-m10x25","provider":"HS Tuning ","version":"1.0","type":"link"}
