BEW engine timing belt replacement procedure from MOGolf (as demonstrated on a 2004 Jetta). Based on the procedure published by Volkswagen, but modified for the “average” shadetree mechanic. Some special tools are required. Tools can be sourced from www.metalnerd.com, or genuine VW (and OEM suppliers) tools from www.zelenda.com, www.samstagsales.com, and other vendors of tools for VW vehicles.
You will also need a means of supporting the engine from above or below, with some mobility forward and aft. The following steps are in the sequence I recommend. It is easier than the sequence published. First, make the coolant expansion bottle “mobile”. The coolant expansion bottle is the round ball on the right side of the engine compartment with a blue cap. Disconnect the coolant line and cap off the nipple.
Then unclip the hose from the rigid intake pipe. Then disconnect the sensor. The bottle is held in place by two Phillips head screws. Remove them.
