I'm trying to remove the cap on the hydraulic tensioner pulley so I can de-tension the belt to get at the water pump. I searched, but didn't see anything directly related to removing the cap.. just 'remove the cap'.

Part #18

Is there a tool that I'm missing to get this off without breaking the plastic pulley?

I just want to get this stupid thing off to get the car back together. I had no prob getting the A/C belt off because it's mechanical tensioner, but I can't get the hydraulic pulley cap off.

Any advice?

Haha.. wow that was easy.

Thanks man. Now I just need to find my 3" extender for my rachet. I bet they have one at the hardware store.

Thanks!

That's what I've noticed about working on this car compared to say the mustangs I worked on earlier in life... When you're working on a BMW, if something is hard to do, you're probably doing it wrong.

True statement, I have been impressed with how maintenance friendly many of the designs are on the BMW systems.

On your tensioner, It takes a lot of torque be careful not to let the bit twist under torque, you may need a breaker bar for leverage. Best if you use both hands and have someone else slip off the belt.

Be double sure to use the correct size torx bit, the next size down feels like it fits but will strip the torx if used.

I'm already done. Just waiting on the aluminum pulley on the mail truck and i'll be on the road. EMP Stewart pump and new thermo installed.

Thanks again.

OK, good thing the mail isn't here yet, or I probably wouldn't have noticed; it looks like the bearing in the tensioner pulley is shot. Looks like I'm going to be in the civic for another few days.

Hey,

I didn't have a DIY. Are you trying to get the pulley off or the whole unit? The pulley is just an 8mm hex; the people who say it's a torx must be talking about the mechanical one. I used a brake caliper 8mm socket on a 2' breaker bar and it came off easy. Then you can get to the mounting bolts.

Tensioner itself
