O-Rings in Evaporator Core TSB

[Ecto1]

The Evaporator Core TSB lists 2 O-Rings for the A/C lines. The TSB doesn't indicate where these O-Rings are located. Are they attached to the AC lines under the hood that fit into the TXV? Or are they attached to the AC lines on the Evaporator side where they fit into the TXV?

Thanks.

The O-Rings called out in the TSB are for the Engine Bay side of the TXV. The tubes on the Engine side and the Evaporator side are different sizes. I purchased a new Motorcraft (Ford) TXV which includes the Evaporator side O-Rings. If you transfer your old TXV to a new aftermarket Evaporator you'll need the O-Rings. If so you'll have to find the O-Ring part numbers. I suspect you'll have to visit the Ford Dealer Parts Counter to find them.
