Dorman Improved Design 667-023 Turbocharger Line Replacement Kit Compatible with Select Buick/Chevrolet Models (OE FIX)

Coolant line for turbo is leaking from turbo. Coolant line was loose. Needs improvement on this. Dorman come on you can do better than this.

Great quality for the price, but use copper washers instead of the included bonded seal washers. There's no reason to save pennies, copper washers have been used on turbo cars for decades and last significantly longer than whatever rubber is on those washers.

Perfect fit for my 2018 Buick Encore!! Great value too!

I bought this Dorman kit because it actually saves you a decent amount of money over OEM...that is, if it works. Installed both turbo coolant lines without any issue, but a day later the car is leaving a hand sized puddle in the driveway. Oh well, back into the shop. Found both connectors (these house the only seal, a single o-ring) would leak if I pushed on the lines. I had never had this problem before using OEM GM parts. Took it all apart, which is a frustrating and time consuming job because when you pull the lower line, you will get a good pint of coolant running down your arm because it's the lowest drain point in the block. Since these are one-time-use connectors, you have to literally beat them apart (quite cathartic). What I found was, they screwed up the machining, and the bore is large enough that the tube can just wiggle around in there, and there's no way the dinky little o-ring can compensate for how loose it is. Measured the GM fitting and found it's 0.025" smaller bore, which hugs the tube much better and doesn't allow the wiggling you can see in the video. None of my GM units has leaked. Dorman engineers: please do a better job next time. This is a simple bore callout in the CNC code. I wonder how many thousands of kits you have out there that are all wrong. My second beef with this kit: I have installed 3 of the metal turbo oil drain lines and all 3 have leaked at the turbo flange. One would wonder how you can screw up a flat bolted flange seal, but they did. The seal provided is perfectly flat and not embossed like it should be. Gaskets need some amount of "crush" to work correctly, and these don't have any embossed ring at all. I know I had them torqued properly, so installer error is out of the question. The proof in the pudding is, on all 3 cars I tossed the Dorman gasket and used some extras I had from GM and Elring. And those all worked. So...once again guys, your seals don't seal. To anyone reading this, if you can't get a correct gasket, use GM assembly adhesive (the gray stuff that starts setting in 10 minutes). It will probably help you out.

Installed on a 2012 Chevy Cruze. These lines were installed on a new Dorman turbo unit. All lines worked and fit as designed. I installed the oil return line in the oil pan first and then attempted to install it to the bottom of the turbo. It was hard to line up and install the two (2) bolts to attach the oil return line to the bottom of the turbo unit but after several attempts and time I was successful. The coolant line from the turbo to the engine block was also rather a pain to attach to the block. I was necessary to take off the thermostat housing to finally be able to get it lined up and tighten down. I did not need the special banjo tool to hold the fitting to tighten. All lines installed with no leaks or problems. Would buy them again.

A must have when replacing the turbo

I liked both of the oil lines. They look great and they have fit well. The return line is metal instead of plastic and it fits perfectly. I had trouble with the new coolant line’s leaking and had to put the original ones back in with new gaskets.

Great quality, perfect fit, solved leakage, a little too expensive by the time I bought it, which was around $100, and despite that, it's totally worth it.

Great quality parts! seals already on and capped off so nothing can possibly get inside. Tried a cheaper set and that was a mistake! Installed these and no leaks at all! Very happy that it fixed the issue I was having.

Me asombro la calidad del producto muy buena resistencia y acabados

Had hassle installing oil return line but it is worth installing. It is costly when I did purchase.

Replaces oem equipment supperior in every way plus the return pipe is metal so no worry of it meltimg from heat or breakimg i side the engine block if service is necessary

i received it just like the photo
