Skoda Workshop Service and Repair Manuals

Removing   Caution When undertaking all installation work, particularly in the engine compartment due to its cramped construction, please observe the following: t  If the toothed belt is replaced when carrying out engine repair (apart from regular change interval), it should be entered in the Service Schedule! t  Lay lines of all kinds (e.g. for fuel, hydraulic fluid, cooling fluid and refrigerant, brake fluid, vacuum) and electrical lines in such a way that the original line guide is re-established. t  In order to avoid damage to the cables, ensure that there is adequate free access to all moving or hot components.   Note t  Safety precautions when working on the fuel supply system → Chapter. t  Observe rules for cleanliness → Chapter. –  Put the shift lever into Neutral in order to turn the crankshaft. –  Switch off ignition and withdraw ignition key. –  Remove engine cover → Chapter. –  Remove V-ribbed belt → Chapter. For vehicles Fabia II, Roomster

–  Disconnect the plug connection -2- at the differential pressure sender -G505-. –  Release screw -3- and remove differential pressure sender -G505- from bracket. –  Place the differential pressure sender -G505- with line to the rear. Continued for all vehicles

–  Separate fuel feed line -2- and fuel return-flow line -1-, to do so press the release buttons. Unlock the quick coupling and disconnect → Chapter. –  Collect the fuel which flows out with a cloth. For the vehicles Fabia II, Roomster

–  Unlock the catch peg with a finger and pull the fuel preheating valve upwards out of the guide of the coolant expansion bottle. For vehicles Rapid

–  Unlock the catch peg with a finger and pull the T-piece upwards out of the guide from the coolant expansion bottle. Continued for all vehicles –  Unclip the fuel line from the plastic holders.

–  Push the catch pegs towards the outside and remove the fuel filter towards the top. –  Place the fuel filter and the fuel hoses together with the fuel preheating valve on the engine. –  Remove fuel filter bracket.

–  Unscrew the screws of the coolant expansion bottle -arrows-. –  Remove the plug -1- from the expansion bottle and push the expansion bottle to the side.

–  Remove top part of toothed belt guard; to do so release retaining clips -arrows-. –  Remove crankshaft-belt pulley → Chapter.   Note Do not lock tensioning element for V-ribbed belt.

–  Release screws -arrows-. –  Remove bottom toothed belt guard. l  Remove the engine support before exchanging the tensioning pulley and removing and installing the toothed belt.   Note t  The assembly bracket must only be removed if the engine is supported with the supporting device -MP9-200 (10-222A)-! t  Only release the engine support if the assembly bracket is removed. –  Remove engine support → Chapter.

–  Rotate the crankshaft on TDC in direction of rotation of the engine and remove the crankshaft timing belt sprocket with the crankshaft arrester -T10050-. Slide the crankshaft arrester from the front side of the toothed belt sprocket into its teeth.   Note The markings on the crankshaft - toothed belt sprocket -2- and on the crankshaft arrester -T10050--1- must be aligned. While doing so, the stud of the crankshaft arrester -T10050- must engage in the hole of the sealing flange.

The arrow on the camshaft sprocket must be close to the »12 o'clock« position.

–  Slacken the screws -arrows- for the camshaft sprocket by approx. 90°.

–  Slacken the screws -2- for the toothed belt sprocket at the high pressure pump by approx. 90° using the socket insert XZN 10 -T10385-. Tensioning pulley A

–  Loosen nut -1- for tensioning pulley. –  Turn the eccentric of the tensioning pulley with the offset screwdriver -T10264- in -direction of arrow- (anti-clockwise), until the tensioning pulley can be interlocked with the rig tool -T10265-.

–  Afterwards, turn the eccentric of the tensioning pulley with the offset screwdriver -T10264- in -direction of arrow- up to the stop and tighten nut -1- by hand. Tensioning pulley B

–  Loosen nut -1- for tensioning pulley. –  Turn the eccentric of the tensioning pulley in -direction of arrow- (clockwise) using the offset screwdriver -T10409- until the tensioning pulley is slackened (eccentric element in approx. 9 o'clock position) and tighten the nut -1- by hand. Proceed as follows for both tensioning pulleys   Caution Risk of damage through reversing the rotation direction of an already used toothed belt. If the toothed belt is re-installed, mark the direction of rotation with chalk or a felt-tip pen before removing it. –  First of all remove the toothed belt from the large guide pulley and then from the remaining toothed belt gears.
