1998 Volkswagen Passat Glx timing belt removal and installation

1. raise and support vehicle. remove front, lower engine cover. lower vehicle. separate release lever from hood lock. remove front bumper cover. see fig. 1 . remove bumper carrier from impact damper. 2. unbolt air duct between lock carrier and air cleaner on lock carrier. remove support bolt on passenger side of lock carrier and insert one lock carrier guide (3369) into hole. see fig. 2 . 3. remove lock carrier front support bolts. remove lock carrier-to-side panel bolts. insert lock carrier guide (3369) into hole on driver’s side of vehicle. slide lock carrier forward on lock carrier guides. 4. on vehicles with a/c, mark direction of rotation on belt, and remove a/c drive belt. on all vehicles, rotate accessory drive belt tensioner clockwise to remove tension from belt. mark belt with rotation direction, and remove accessory drive belt. see fig. 3 . 5. remove accessory drive belt tensioner pulley and lever. turn crankshaft to tdc of compression stroke on no. 1 cylinder. see fig. 4 . 6. remove crankshaft pulley. it is not necessary to remove center crankshaft pulley center bolt. remove upper and lower timing belt covers. loosen timing belt tensioner lever bolt. 7. if reusing timing belt, mark belt with arrow to indicate direction of rotation. remove timing belt. installation caution: when turning camshaft, crankshaft must not be at tdc or there is a potential for valves to contact pistons. install timing belt when engine is cold or lukewarm. 1. align timing marks on camshaft sprocket with mark on cylinder head cover. see fig. 4 . ensure crankshaft is still at tdc position. install timing belt around crankshaft sprocket. temporarily install crankshaft pulley to ensure crankshaft is still at tdc of compression stroke for no. 1 cylinder. 2. place timing belt on intermediate shaft sprocket, tensioner pulley and camshaft sprocket. to tension timing belt, use spanner wrench to rotate tensioner pulley clockwise until tensioner piston no. 1 is fully extended, and tensioner piston no. 2 lifts about .040? (1 mm). see fig. 5 . 3. tighten tensioner pulley bolt to specification. see torque specifications . rotate crankshaft 2 revolutions. make sure camshaft and crankshaft timing marks are aligned. 4. belt tension is correct if edge of tensioner lever aligns with piston upper edge (area “a”), or piston no. 1 is extended 0.98-1.14? (25-29 mm) (dimension “d”). see fig. 6 . check for wear in areas “b” and “c” if dimension is not correct.
