2013 Cruze LT
So, the replacement hose should have a oring in there. Mine leaked if I moved it by hand, I replaced the thermostat assembly and it fixed it. I was worried it may blow off or something, so I opted to fix it immediately.I have a 2012 LT. Recently replaced radiator hoses. Now it appears I have a leak where lower hose connects to thermostat outlet. Since it uses a clampless connection not sure how to tighten this up. It seems to only leak after stop and go driving not really highway. Not a huge leak but it has me concerned.
