I’m in the same boat. I started removing my turbo last night. There’s a 17mm bolt that connects one of the water lines to the block that’s a real CU Next Tuesday.

@Thebigzeus What size rubber hose did you use to replace the coolant return line? Has it held up over time or was this just done? Mine leaks occasionally, but seems to be a costly repair at the dealership. Any other tips you learned while replacing this part?
It is expensive up to 1000$☹, when you have the turbo out might as well as do the oil cooler as well

This is the hose I used: Amazon.com: Vibrant Performance 20412 Heater Hose: Automotive (but not at the price they're asking now)

Gotta use those specific clamps too, the ribs on the worm clamps cut into the outside of the hose. It was done about a month ago, no leaks yet, pressure tested for 8 hours.

I just wrapped up replacing that line. With as big of a pain in the ass it was to remove that turbo, I wish to god I would have replaced everything back there.

I thought this Turbo coolant hose was available on rockauto if I recall correctly. Maybe installing a generic hose with clamps allows you to access this coolant line without removing the turbo.

9 years, knock on wood, I have not had to pull the turbo or the oil cooler, but I've watched several video's for when that day comes.

One of the coolant lines that's 17 mm can be reached with an open ended wrench once you remove the complete air box assembly. I remember seeing one person go in via the side with what I believe was a 17mm open end.. and another person used a long extension and a socket, coming nearly all the way out to the radiator with the ratchet.

Done the water pump, thermostat gasket, coolant outlet, coolant bleed hose to tank, upper radiator hose... I sopose these turbo lines are probably the weak link of my coolant system, but so far the coolant is tight. Tighter than the day I drove it off the lot new.

Good Luck-

The turbo coolant line must be replaced when you do the turbo. I did a quick fix on this known problem leaker as follows: didn't even have to drain the coolant
1) Remove manifold heat shield
2) Confirm leaking coolant ( had a burning smell off and on until, when changing the oil this weekend found and traced a puddle of coolant to this hose, where the rubber hose is swagged to the metal line.
3) Removed lifting eye on engine head to work on hose
4) Carefully cut the metal swage off (careful not to damage the hose underneath) with a dremel and metal cutting wheel
5) Cut a 1/4 inch off the rubber hose
6) Removed hose quickly and slide the aluminum heatshield tubing off to reuse
7) Quickly put hose back on the steel line with hose clamp and tightened the clamp.
8) Cut the heat shield tubing on the inside longitude leaving space for the added clamp to insuring it goes as close as possible to metal line). Fit it neatly back in place with cut facing toward the engine block
9) Clean up the old swage fitting of sharp edges and reinstalled it over the end that was just repaired right up to the hose clamp. Clamp it carefully with channel locks (this was to provide additional heat shielding to the end under exhaust Manifold)
10) Check for leaks
11) Stand back, take pictures, have a beer, and think about the savings- (the price of a 1/4 inch hose clamp)

2012 basic cruze - I'm just finally getting around to changing the oil on Wolfe Island and finally seeing a big enough coolant leak to understand where the smell has been coming from for a while now. I figured I'd share how if fixed it for those chasing the same very expensive issue if taken to a dealer...LOL
