Cant figure how to clear the p0455 code? out
SOURCE: Drain coolant in 2003 Chevy Impala
hey, i just flushed out my coolant system a month ago. it is located (if you face the front of the car) on the bottom right. it will drain straight down to the ground and you have to unscrew it from the back of the radiator. it is covered by a pastic piece and sits right on the radiator frame. hope that helps some!!

These codes are for the evaporative emission system.The 455 is the vent solenoid.The 455 is a large leak in the evap.system.The vent solenoid I would replace because they go bad and will not work because they are under the vehicle in the rear of the truck.There is a bulletin for these and the vent valve is installed in another spot.The number for the bulletin is 02-06-04-037E.You should also look for a broken or loose hose or pipe that might have came off.Specially if you ran over something.If none found it could just be the vent solenoid stuck in the venting position.Good luck.

drive car at least 1 day to see if light goes out. if not, go to any auto parts store and they will turn light off with a OBD-II scanner. auto-zone etc. if it comes back on its another problem. another leak or damaged piece in evap system. check evap system if need be. have a good day ! p0455 evap leak ( large ).

There is no magic bullet fix for this, you can have a leak you can't see or a defective fuel tank pressure sensor or a defective vacuum line, the list goes on.
