I have taken the oil cooler apart and removed the hard line from the oil cooler pedistal. I need to get the crush washers before I can put everything back together. Trying to match up the crush washer size, it looks like it may be an 18mm... can anyone confirm this? Also, does it matter if I get a copper or aluminum crush washer? They are the same type of washers that are used for oil drain plugs, right? Just want to make sure I'm using the right ones... really don't want to have to take this thing apart again for a long time!

Thanks!

 

If you're talking about the banjo bolt at the bottom of the rear iron then yes, it's 18mm. You can use copper or aluminum. I prefer copper, but they're usually more expensive.
