They tell the techs to remove the air filter box assembly. This involves disconnecting the MAF sensor, the band connector to the tube from the air filter to the resonator. Then removing two bolts and loosening one nut on the air filter box assembly, and removing the box from the vehicle.
The connector side of the pump is in the lower part of the reservoir, facing the air filter assembly. This is the location where the number is stamped.
I was able to slide a mechanics mirror (small mirror on a expandable rod) between the air filter assembly and the pump. You need a lot of light, a flashlight might help, but I was lucky, and had one of the few sunny days in MI.
If 345R is stamped on the electrical end of the pump, it is not part of the recall.
From what I have learned, the majority will not have this number.
Once the air box assembly is removed, it is easy to replace the pump.
I would recommend if you are taking the vehicle to the dealer, have as little washer fluid as possible inside the reservoir. Makes it less messy for the techs.
You should not receive a recall notice unless your vehicle is within the VIN break.
