Welcome Aboard!This is a great thread in identifying a problem and seeing the solutions to help fix it. Too bad my daughter's Cruze has the issue. Long story short, I:
a. Replaced the O-ring on the cap (saw yellowish crust on the cap)
b. Didn't see a decrease in the reservoir's fluid level after getting the Cruze up to operating speed
c. Didn't notice any leaks
So after my test run, the reservoir's level didn't change. I thought it would be less but, maybe I didn't run it long enough to make that difference. Anyways, after the test run and looking at the engine I noticed the sound where it seems like air and fluid are exchanging places.This lasted for over 3 or 4 minutes after turning the car off. I have a video that I can post, but, this site won't allow links in first posts. However, my phone was placed between the fan and engine and more toward the driver's side. I can only assume that I need to bleed off the air in the cooling system and will do so. But, could this sound be coming from any other areas/systems in my engine bay and/or is this sound normal?
Thanks in advance.
Post some more threads and put your video on YouTube and post that link here.
