2013 FL2 HSE - front airbag sensor location and part number

My car’s radiator pack has been replaced and now the airbag lights are on and I’m suspecting the airbag sensors have not been placed back, as I did a bit of research and it seems to be located in that area. Can you please let me know where the front sensor should be and its part number? Or would a missing sensor result in the airbag lights to be turned on?

Go back to where the cooler pack was replaced, and get them to rectify the issue.
There are 2 impact sensors on the cooler pack upper mounting.
If the sensors aren't in the system, the airbag warning light will be on, and the airbags will have reduced operational capacity, or be disabled altogether.
The place that did the work which caused the issue have broken the law, because they allowed the vehicle to leave in a dangerous condition.
