Where would the hose on the engine 1.5 DADA
Looked at service manual but still nt clear what pipe I should be looking at.

Should be on each side of the radiator. I think the feed hose is on the right (if you sit in the car) and the exit hose is on the left (again, when you sit in the car) right in front of the airbox.
