Removing For engines with identification characters AUA, AUB, BBY, BBZ, BKY

–  Pull off hose -1- (for engines as of 04/2002) and remove engine cover -2- with air filter upwards -arrows-. Continued for all vehicles –  Remove V-ribbed belt → Chapter. –  Remove top toothed belt guard. –  Remove the front right wheelhouse liner → Body Work; Rep. gr.66.

–  Position crankshaft on TDC for cylinder 1. The notch on the belt pulley must be aligned with the edge of the marking -A-.

–  The locating holes in the camshaft sprockets must be aligned with the fit holes in the cylinder head cover -arrows-.   Note If the locating holes are positioned on the opposite side of the toothed belt sprockets, it will be necessary to rotate the crankshaft a further revolution. The engine must be lowered as described below in order to be able to remove the crankshaft belt pulley:

–  Install supporting device -MP9-200 (10-222A)- according to the illustration. –  Remove the top securing screw from the bottom toothed belt guard below the engine mount. –  Slacken the coolant expansion reservoir and lay aside.

–  Take up the weight of the engine and remove the fixing screws -A- of the engine console on the support of the cylinder head.

–  Remove the fixing screws -B- of the engine console on the body and remove console. –  Remove the engine mount on the cylinder head. –  Lower engine in such a way that the fixing screws for belt pulley are accessible. Fix the two camshaft sprockets with camshaft lock -T10016- as follows:

–  Insert the two locking pins through the locating holes of the camshaft sprockets up to the stop in the fit holes in the cylinder head cover.   Note The two locking pins are correctly inserted if the end parts -D- are flush with line -A-. –  Slide the support -B- up to the stop on the camshaft timing gear -C-.

–  Counterhold belt pulley with counterholder -T30004- with inserted replaceable bolts -T30004/1- and release the fixing screw for V-ribbed belt pulley and crankshaft - toothed belt sprocket. –  Remove belt pulley. Screw in a fixing screw with two washers to secure the crankshaft - toothed belt sprocket. –  For vehicles with air conditioning system remove the V-ribbed belt tensioning pulley. –  Remove bottom toothed belt guard. –  Mark the rotation direction of the two toothed belts.   Note The camshaft sprockets must not be interlocked when inspecting the tensioning pulleys. Check main drive tensioning pulley

–  Mark the pointer position of the tensioning pulley -arrow-. Load timing belt by firmly pressing down with thumb. The pointer must move. –  Relieve the toothed belt again. –  Turn the crankshaft two turns in the running direction of the engine. –  Check pointer position. The pointer must return to its initial position. If the pointer does not return to its initial position: –  Replace tensioning pulley. Check coupling drive tensioning pulley

–  Mark the pointer position of the tensioning pulley -1-. Load timing belt by firmly pressing down with thumb -arrows-. The pointer must move. –  Relieve the toothed belt again. –  Turn the crankshaft two turns in the running direction of the engine. –  Check pointer position. The pointer must return to its initial position. If the pointer does not return to its initial position: –  Replace tensioning pulley. Remove main drive toothed belt:

–  Release the fixing screw of the main drive tensioning pulley -1- and release the toothed belt by turning the tensioning pulley in the -direction of arrow-. –  Remove tensioning pulley. –  Remove camshaft lock -T10016-. –  Remove timing belt. –  Fix the two camshaft sprockets with camshaft lock -T10016-. Remove coupling drive - toothed belt

–  Release the fixing screw of the coupling drive-tensioning pulley -1- and release the toothed belt by turning the tensioning pulley in the -direction of the arrow-. –  Remove coupling drive tensioning pulley. –  Remove timing belt.
