Hello all, I'm not a Cruze owner, but I do own a Silverado. I'm working on a friends car and need a little help. I removed the thermostat housing today, and the small diameter hose/pipe that attaches to the top of the housing broke. The pipe in question has a plastic fitting and runs to the back of the engine then turns 90 degrees and runs to the passenger side of the car. I believe it might be Throttle Body Inlet heater hose. Can anyone verify this for me? I appreciate any help you can give.
