Buy a new overflow hose and outlet. I usually keep 3 of each in stock. People who just buy one always come back for the other. The new outlet comes with seal, bolts, and sensor. It's not that expensive, but I can't remember the current price off the top of my head. The whole job should be less than $100 in parts and coolant though.


I don't see any of those parts at Rockauto. You said coolant? I thought it looks like an oil line, I seen oil or some dark fluid come out of it when I messed with it.


Yes, that part is a coolant outlet. They don't sell the plastic fitting the hose connects to by itself, even though you can remove it from the outlet. The current GM part # for the outlet is 25193922 and list is $44.11. It has changed numbers a bunch of times.

It is listed on Rock Auto under "Thermostat Housing/Water Outlet"...
http://www.rockauto.com/en/moreinfo.php?pk=6755172&cc=1501801&jsn=438

The outlet doesn't house the thermostat, that's on the other side of the engine on the water pump, it's just listed in the same section of the catalog.

For whatever reason Rock Auto doesn't list the hose, but the part number on it is 13251447. GM list is $19.94.

Pretty much any Chevy dealer should have both in stock.

Got one off eBay and plan to change at 100k here shortly just as PM

That housing looks like it's got a lot to it,do you know if it's a big job?

Yes, the automatics don't respond well to poor fluid, which gets that way fairly quick. (30K?) Part of the Cruze's bad reputation and "teething problems" was due to the OLM on the '11 and '12's being calibrated for 10K intervals on syn blend Dexos1 oil which just isn't adequate for a turbocharged engine of that power density. Mine's a '13 so it has the updated OLM calibration, turbo oil feed line, etc., but I got it new and changed the oil at 2K, 6K, and every 5K afterward (mostly on Synpower 5w30, but a little Mobil1 and Schaeffer's) and have had none of the failures the cars are known for. Original battery, water pump, PCV valve, turbo, clutch, etc. Air filters every 40K, plugs every 60K, Seafoam in the tank every 10K, tire rotations every 7,500. If you're doing pure highway driving 7,500 OCI's shouldn't be a problem on a name brand synthetic, but mine has rarely seen a full interval of highway driving so I just keep it @ 5K to keep the numbers round. Also, some people report the 1.4T running best on premium fuel; in mine I can't tell the difference between premium and 89, but the consensus is they run like dukie on regular.

I got mine (plus the hose to the reservoir) off Amazon and it took about an hour and 1/2 gallon of (Dexcool) antifreeze. The plastic just gets soft and it cracks>seeps - it's not a real hard job, just don't tear into it and the hoses/wiring harnesses around it like a coyote after a varmint gone underground. After you're finished, refill with 50/50 antifreeze and distilled water then let the engine sit and idle with the cap off until warm, topping off as needed. Then put the cap on and drive it, making sure the temp doesn't come up higher than normal. I've heard plenty of stories of people doing cooling system work on these, then getting a bubble in the system that causes them to overheat.

FWIW I don't remember actually draining the cooling system - I think I just cracked the outlet loose and let it drain as far down as it needed to, then proceeded with disassembly.

I'd drive it down to Campbellsville, KY and see if Alex will do some work on it for you. Two and half hours to get it dialed in will be worth it. Esp if that helps keep it be trouble-free for years to come.

Huh! I hadn't even looked at his location - not a bad idea!

I have an appointment to drop the car off at the dealer next week as part of the agreement when I bought it to repair a hole in the front bumper cover and they said they will look at the coolant leak at the same time.

I wonder if there's any software updates for my model? Like OLM recalibration or transmission updates? I checked the VIN for recalls and it has none.

I believe the tune was updated in 2014 or '15 with a few tweaks. I want to say that update cost a little gas mileage but fixed the OLM on older cars and fixed a couple bugs, but I never paid a lot of attention because my '13 was in the sweet spot between the overly optimistic OLM and the downsides of the later update.
