What are these palstic tubes on a 2001 Impala 3.8L?
I have a 2001 Impala 3.8L. I popped off the engine cover because I need to change the thermostat, and noticed that two tiny plastic lines are broken. They go in to something (not sure what, I'm still learning) that's basically directly above the thermostat housing. In the image at http://ww2.justanswer.com/uploads/djenn434/2010-12-27_234940_solenoids_0000.jpg they start together, on the far right towards the middle. The right-hand line from the number two passes over them just after they elbow; after that, they split and go to different things. Both of these are broken where they join that structure above the thermostat housing. The car seems to be running fine. I suspect they're lines for O2 sensors or something but that's a guess...the check engine light is on. I'd just like to know what they are and what to search for to find a replacement. Any help would be greatly appreciated.

The first thing to do is get the computer scanned for trouble codes. You should come up with codes for the EVAP system which is how the computer vents the gas tank to the vapor canister. O2 sensors are mounted in the exhaust pipes and don't use vac lines.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

No one ever said new means good. Try another thermostat. Make sure it is the recommended temp for the vehicle. I would spend the extra money to buy a dealer thermostat. What controls temp is restriction of flow thru the system until a set temperature is reached and the thermostat opens. Has to be a thermostat.
Does your fun run when the AC is turned on?. Check your FanCont2" and "FanCont3" fuses in the fuse compartment, if these are open, that will cause the code to pop, if either one burned, replace and reset computer with scanner. However you seem to have an actual issue, possibly with the fan motor, make sure your fan is running, also you could possibly have a semi closed stuck thermostat, remove it, then put it in a metal container with water, put it on the stove to heat up, once the water heats up the thermostat should open all the way, if it doesn't then replace it, either way, by testing it, you rule out that possible issue... Good luck.
go to an auto supply house buy a Chilton's or similar repair manual for the 2001 chevy impala but a thermostat and follow the instructions in the repair manual. it is a really simple repair and the manual will have step by step instructions for you. THX for rating/voting, etc.
If you have done this already,then bleed the cooling system,this is all you lack,just get the air out of the system,two bleed ports,one on the thermostat housing,and one on the engine near the water pump,just bleed them out as the car warms up,the thermostat bleeder last,if this was at all helpful,please rate,thank you.
To get to the thermostat you need to remove air cleaner box assembly from the throttle body and move it out of the way. Next, remove the nut at the throttle body that holds the steel tube that goes to the heater hose, remove all hoses that connect to this tube and raise it out of the way. Remove the steel line that goes to the radiator surge tank from the thermostat housing. Now the fun part. With a 13MM box end wrench, loosen the lower bolt from the thermostat housing. A 13 mm socket will remove the top bolt. Remove the thermostat cover and remove the thermostat. Reverse to install.
Please chek this link for replacing the thermostat...
there air 2 air filters located inside the black, plastic engine cover assembly. remove the 2 accordion like inlet tubes on each side of the engine cover/airbox. yank straight up from the back of the box closest to the windshield with a little force to remove the entire air box/engine cover assembly. you will need a #20 torx bit driver. turn the air box upside down and loosen all the torx bits on both sides. the screws will not come completely out of their holders. remove each rectangular box and you will see the air filters inside. make sure when reinstalling the air box/engine cover, that the round air inlet hole sits properly onto the air mass meter and all 4 corners of the box pop back into their clips
