Review on ACDelco 23258394 Original Equipment Frequency by Kelly Gonzalez

This is a generic OEM replacement at 1/3 the retail price. Works very well for cars that install it on the back of the car. However, on trucks and SUVs that mount it at the front with a beveled nose, the outlet at the rear becomes a filler hole and needs to be sealed with sealant to prevent water from entering the body. I sealed the underside of the aluminum base with silicone caulk as the old one had water in the electronics area and was causing rust.
