So my first issue popped up with the new cruze already. It's not huge but it's something I noticed. There's a damp spot on an oil line next to the oil fill cap. It's not dripping or anything but it's wet all around and when I tried to fuss with the metal clip that looked loose it made it lose a drop of oil so I'm guessing the clip is all the way in. Any thoughts on how to proceed?

I have posted a thread already on the cruze talk but didn't get any replies yet, so I thought I'd try here as well and compare the responses.

The one part I've had to replace on my '13 with 110K is the coolant outlet which is rght below that - and I replaced that hose (which is coolant, BTW) at the same time. I hope you educated yourself on the maintenance needs and common failures of the turbo Cruze before buying one. I love mine but they will not tolerate the neglect most vehicles see from the average owner.

That's the coolant outlet/water neck.

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.

No I didn't do enough research before I bought it, I just saw that they needed transmission service regularly as well as good motor oil. Do you have any tips?

Common weak points include:
- Water pump (common, but covered under a warranty extension)
- Various cooling system hoses and components
- Turbo (less common, but not uncommon)
- Check valve inside the intake manifold (requires new manifold with injectors)
- Valve cover diaphragm failure which results in a lean condition. Usually caused by a failed check valve inside the manifold.
- Front Crank Seal failure and Lower Oil Pan leakage.

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.

I guess it's a good thing I got the dealer extended power train warranty, 4 years 48k miles, with a $200 deductible.

Pull it apart to identify the worn/damaged component.
Replace worn/damaged component with upgraded part.

The gen 1 Chevy Volt, which does not have a turbo, has the same valve cover, but I have not heard of any failures on the Volt.

If the check valve inside the manifold on the Cruze fails, does it allow the crankcase to get pressurized when the intake manifold pressure is in boost?

If so that could contribute to:

Front Crank Seal failure and Lower Oil Pan leakage.


I ran across a mod for the Cruze which uses an external check valve. The internal check valve in the manifold is plugged, and the external check valve is plumbed between the throttle body and the intake manifold.

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.

Other people are reporting they just replaced the hose not the housing... I wonder if that would work?

You can try, just be prepared to replace both. A lot of times the nipple on the hose breaks off inside of the fitting that is part of the outlet. You may or may not be able to dig it out.
