It me again Eg civic D16z6. the radiator takes up half the front and there is a blanking plate where the aircon would be fitted if i had it (I dont). But i have noticed that on some car there is a U shaped tube that goes in this area not sure if it in front or behind the plate. This U tube connects to the passenger side of car. What is it cos i dont have one the two pipe are just linked with plastic hose. Help

 

if i'm right. that's for the a/c freon. is it next to the radiator???

 

yes it is beside it what does it do

 

it's just for the gas for the air conditioner.
