Hi all

We have a 2010 Avalanche with the service airbag message on. The previous owner had it diagnosed by a gm dealer telling him he needed to get one of the front impact sensors replaced Has anyone done this? It appears that they changed the design for 2010 and later from the bolt being inserted from the bottom and being tightened by a 10mm socket to one that comes down thru the radiator support. My question is does the radiator or fan need to be removed to replace these sensors?

Thanks

John
