Well I looked under the hood and saw coolant on my oil filter housing. Can't find where it's coming from. It's a slow leak. Wondering if someone else with the 1.4 had coolant in the same spot and could tell me where theirs was coming from. Already replaced water outlet and breather hose. Doesn't seem to be leaking from there. My only guess is the line behind the heat shield. Thoughts?

I don't think there's anything that can get there from a slow leak - more like an intermittent spray at the right temperature and pressure. I think I'd pop the hood after bringing the car back home and watching for 10 minutes. That seems to be when most of the weird leaks happen.

I have coolant there too, along with a slow leak. Ive given up on finding it so i just keep refilling the coolant.

After a closer the line is not wet. It just appears that way in the light. I felt all the houses on the outlet where I thought it was leaking but I couldn't find any coolant or the syrup feel of dried coolant. My question now is, my car has 62k miles. Would it be covered under the power train warranty? My valve cover has a slow leak that I can see from residue around the front of it. Are both of those covered under warranty? I perform all my own maintenance and the car has only been to a dealer for recalls.

The power train warranty is still in effect, but I think you're going to have to come up with a good complaint. Cosmetic isn't going to cut it. Coolant loss will depend on where it's coming from. (And the lines are not covered.)

It's a common problem in these engines.
The leak comes from the big coolant hose that comes from the radiator and attaches to the water outlet, that is bolted to the engine.
This whole assembly is above the oil filter. You can feel the leakage with your fingers if you touch the end of this hose at the lowest point.
Also check the water outlet for cracks!

As for the water outlet I have replaced it myself and I can't see or feel any leaks from it. My old one was cracked where you described. I also replaced the breather hose that connects to the top of the outlet. As for the valve cover I called my dealership and they said for them to look at it I would have to pay a diagnostics fee and if it was covered under warranty it'd be free. So instead I am getting a free inspection of the vehicle on Saturday and maybe they'll look into the coolant and tell me what's wrong with it. I don't want to tighten the bolts incase it is covered under the warranty and they claim I over torqued it and make me pay for the repairs. If I hear anything about the coolant I'll let you guys know. Thanks for the replies.

In my case the water outlet isn't cracked, but it was leaking there. The spring that clamps down the big water hose isn't strong enough, or the pressure inside the cooling circut gets so big that it leaks there.
After replacing the thermostat, the leak stopped.

I recently had to replace the overflow coolant outlet hose that sits very high and goes right into the coolant reservoir tank. It cost $171. I got $56 back because I have an extended warranty but had a $100 deductible.

I think they did you an injustice with what they charged you to replace that hose. You can buy the hose for around $9, and it takes about 3-5 minutes max to replace.

I just got my 2011 Cruze LT RS auto a week ago and almost right away i could smell coolant. So this is what i found under the hood. I might have to look closer at the hoses to see if there are any cracks or holes. Hope is is nothing serious. I paid for a 2 year bumper to bumper warranty as well. Want this car to last me

Wimpy coolant hose solution

The little hose that goes back to the coolant tank failed and leaked. When I took it apart I was alrmed to see how patheticly thin it was and am surprised it has last 87,000 miles.

So I made a part on the lathe.. I pulled out the insert which is a 5/8ths OD tube with an O ring and a groove for the spring clip.

I simply copied the bottom part on the lathe (I used steel as it was what I had) and made a thick top into which I drilled/tapped a 1/8th NPT thread and screwed in a 5/16ths hose adapter. I then cut the end oh the hose with the plastic clamp arrangement and connected the hose with a hose clamp as shown.

Looks a lot beefier than the original.

Nice! Between that and Extreme's pcv solution I think this board has solved all the gen 1 weaknesses. GM should pay you guys. ;)
