  • How do you take the old stock adapter off?

    Use a small flathead screwdriver or pick to compress the two locking tabs on the quick-disconnect collar and pull it off the firewall tube. Then, carefully cut or slice the permanent metal crimp ring on the rubber hose using side cutters to fully release the old plastic fitting.

  • Does this order come with two connectors, or only one?

    One connector per order.

Customer Reviews

Overall rating: 4.4 / 5 from 7 reviews.

The ai assistant on dirty diesel.com told me I needed this part. I asked it what parts I needed to go from the coolant bypass tube, to the turbo. After ordering my parts on a Sunday, I looked into the part numbers the next morning. Realizing they were incorrect, I emailed the sales team to pause my order houses before they opened on Monday. It also included two engine to firewall coolant hoses. Which I also didn’t need. Tuesday afternoon my parts were shipped. I’m sure the parts are great quality. But I have no use for them. Maybe one day I will install them.
