Please Note: In some cases you might have to raise the passengers side of the engine to better access the motor mount bracket fasteners.
How To Step 21
Raise drivers side of engine to remove motor mount bracket.
Please Note: This can be difficult. Make sure all fasteners have been fully removed from the bracket so they are not in the way. Lift bracket up and then forward toward front of car. You may have to lightly pull on the a/c evaporator pipe to allow the motor mount bracket to clear. If you are unable to remove the bracket towards the front, you will need to remove the turbo air intake pipe in order to remove the motor mount by moving it towards the rear of the vehicle.
How To Step 22
Rotate engine clockwise until engine timing marks align. The proper timing marks are as follows (A) The crankshaftis aligned properly when tool T10100 is inserted into the crank pulley toothed gears and threw into the round hole in the
oil pump casting. At the same time there will be a line on the crank pulley toothed gear that should be aligned with thearrow on tool T10100. (B) The camshaft is aligned properly when the single tab on the camshaft hub is aligned with the
arrow on the rear timing belt cover. This is on the lower right side of the camshaft sprocket just above the tensioner.If one of the timing marks do not align rotate the engine another revolution and check your timing marks again.
How To Step 23
Double check that crank tool T10100 is properly installed and the timing mark is lined up.
Please Note: NEVER use tool T10100 to torque crank fasteners.
How To Step 24
Install tool 3359 into camshaft sprocket hub. Slide tool into empty slotted hole at left of camshaft sprocket hub.
Please Note: NEVER use tool 3359 for torque of cam fasteners.
Please Note: you may have to tap gently on the pin tool to get it into the hole of the hub and rear casting.
How To Step 25
Loosen the (3) 13mm bolts holding the outer cam sprocket in place keeping bolts finger tight at this time.
How To Step 26
Loosen and remove timing belt tensioning idler, timing belt, fixed tensioner and water pump.
How To Step 27
Rotate the outer cam sprocket counter clockwise until it stops in the slotted holes. Keep outer cam sprocket in this location threw the timing belt assembly as this will allow proper adjustments later if needed.
Crankshaft Seal Removal and Installation:
Please Note: if the crank seal is bone dry you may wish to leave it alone and not replace it at this time.
How To Step 28
At this time if your going to replace your crankshaft seal remove the crank shaft bolt as should be loose as described in step 16. Using tool 3203, remove lower crank seal. Inspect crankshaft for possible groove from where the old seal rubbed on the crankshaft. Lubricate the sealing lip of the new crank seal with clean motor oil. Using tool 3265, gently tap new crank seal into place. If a groove existed in the crankshaft, recess the new seal slightly deeper so the seal lip rides on a new surface area of the crankshaft.
How To Step 29
Re-install toothed belt pulley and using tool 3099 torque crank bolt to 88 ft lbs + 1/4 turn.
How To Step 30
Most likely during steps 22 and 23 the crankshaft timing mark may have slightly moved. Rotate timing mark back into place and install tool T10100.
Camshaft Seal Removal and Installation:
Please Note: if the cam seal is bone dry you may wish to leave it alone and not replace it at this time.
How To Step 31
As completed in step 21 the (3) outer cam sprocket bolts should be loose. Remove these (3) 13mm fasteners along with the cam sprocket.
How To Step 32
Use tool T10051 to counter hold the camshaft hub and loosen the main center bolt but do not remove. When the bolt has been loosened you will want to loosen the bolt two full turns but do not remove.
How To Step 33
Use Hub Puller tool T10052 to remove camshaft hub. To properly use this tool align the (3) bolts on the tool with the threaded holes in the hub and fully thread the (3) bolts into the hub.
Please Note: Lightly torque bolts , but make sure not to over tighten as this can damage the tool.
Next turn the center spindle on tool T10052 evenly and strait until the hub separates from the taper of the camshaft.
How To Step 34
Remove camshaft seal using extractor tool 3240. Inspect camshaft for possible groove from old seal wearing on camshaft seal surface area. Lubricate the seal lip of cam seal with clean motor oil and using tool 10-203 tap new cam seal into place. If a groove existed on the camshaft, locate the new seal a few millimeters outward on the camshaft so that it rides on a new surface area.
How To Step 35
Install camshaft hub to camshaft so that the hub aligns or centers with the timing mark on the rear timing belt cover. Torque camshaft hub to 74 ft lbs using counter holding tool T10051.
How To Step 36
Install camshaft sprocket onto the hub leaving the (3) 13mm bolts hand tight at this time. Line up the camshaft sprocket alignment holes with the hub and install tool locking pin 3359.
How To Install TDI VW Jetta Timing Belt and Tensioners:
How To Step 37
Clean machined area where the water pump will mate with engine block. Install the new improved water pump by turning all water pump fasteners equally snug by hand and then slowly and evenly torque the fasteners to 11 ft lbs.
How To Step 38
Install timing belt tensioning idler. Position backing plate flange on tensioner with machined hole in plastic cover and slide tensioner onto stud. Tighten securing nut only finger tight at this time.
How To Step 39
Install your timing belt working from the crankshaft upward to the camshaft lastly sliding the belt onto the water ump.
Please Note: During this step keep the camshaft sprocket fully rotated in the counter clockwise direction. Also leave the small tension idler pulley off as this will make installation of the timing belt easier. Make sure that the timing belt is properly in place and engaged evenly in the teeth of the lower crank pulley, camshaft pulley and water pump.
How To Step 40
Install the small tension idler pulley and torque to 15 ft lbs.(Apply loctite)
How To Step 41
Using eccentric tool 3387 rotate Adjustable tensioner pulley until arrow on backing plate is aligned with the open gap and torque to 15 ft lbs +1/8 turn.
How To Step 42
Torque (3) camshaft sprocket bolts to 18 ft lbs.
How To Step 43
Remove crank lock tool T10050 and cam lock pin tool 3359 and rotate engine clockwise two full revolutions making sure of no interference or resistance. Check your timing marks and as well make sure the arrow on the backing plate of the tensioner is aligned with the open gap. If tension has changed adjustment is needed and please do so at this time as outlined in step 37.
Warning: Failure to perfrom the above guidelines in step 39 could cause severe engine damage.

How To Fill VW Jetta Cooling System After Timing Belt Replacement:
How To Step 57
Reconnect the lower oil cooler hose to fitting.
How To Step 58
Make sure the radiator drain knob is tight.
How To Step 59
Fill the coolant expansion tank slowly with a 50/50 mix of coolant/antifreeze and deionized/distilled water.
How To Step 60
Install your coolant expansion tank cap, start your engine and allow the engine to warm until the radiator fans cycle at least once or until you are sure the thermostat has opened. You can safely bring the engine up to around 2000 RPM to quickly develop heat in the engine in order for the thermostat to open.
*If the coolant expansion tank fluid level goes down while you are running the engine, turn off the vehicle and carefully remove the coolant expansion tank cap. Re-fill with coolant to the max line and re-start the engine and let warm again
until the radiator fan cycles.
How To Step 61
When the engine has cooled re-check the coolant and add as needed.
