Cambelt Change DIY CXHA?

[HubertK]

Hello,

Long story short planning on doing my own cambelt change on my 2017 T6 CXHA.

I’ve studied Vag tech video and read manufacturer instructions but have couple questions.

1) Is it essential to loosen both Camshaft pulley and also high pressure fuel pump one?

2) I have noticed in videos and instructions that they remove locking tool on the crank pulley before removing old belt. Then readjust the pulley into correct position and insert the locking tool just before installing new belt? Is there a reason why you wouldn’t just lock it into place whole time?

3) Instructions mention “The crankshaft must NOT be in TDC when turning camshaft”.. I’m bit lost as I thought whole idea of locking pins was to lock everything in top dead center position.

I have attached the instructions I was hoping to follow

Doing the job 'properly', then use the tools. That way you know it's done 100% spot on

Now, I'll put my flame proof suit on and give my opinion.

I have only ever used timing tools on these engines once, my own one as I was replacing the high pressure pump. All other jobs have just been done by marking the belt to the pulleys, then transfer the markings over to the new belt. Fit the new belt lining the marks to the pulleys, job done.

This is the way I have done them for more years than I can remember and never had any issues. Not just for these engines, but any that don't have floating crank pulleys.

I bought a set of cheapish locking tools so plan is to try doing it “properly”.

In my head to simplify the instructions and videos I’ve watched. Let me know if it sounds like I’m missing something or doing something wrong?

1) Align engine into TDC position and lock all three pulleys with locking pins.

2) Lossen camshaft and fuel pump pulley to allow movement for tension.

3) Take tensioners, water pump off along with old belt

4) Put new belt and water pump on and tension correctly.

5) Torque everything to spec

6) Turn engine by hand twice and check everything again with locking pins, ignoring fact that fuel pulley might be slightly out.

Sounds fine. Just remember that the camshaft may or may not line up until you loosen the pulley bolts
