Mimmi I spotted what you describe as the red battery angle connector in the Pic . Closer look tells me its the Positive cable .What I see in pic is: There IS aftermarket battery ventilation hose attached to battery with red angle connector.
So I just ignore this hose.
You are right. Your goggles are better than mine.Mimmi I spotted what you describe as the red battery angle connector in the Pic . Closer look tells me its the Positive cable .
Convinced its the Battery vent hose ( mort it fits into the top lip of the battery , there will likely be a small plastic nipple at the battery that the 90 degree elbow ( thats highlighted in the pic ) goes over.
Washers are electric. There are hoses to the headlight washers but that doesn't really look like one. Worth checking if it's not the battery vent.It's for windshield wiper pump..check if you have a check engine light said air leak....if not follow a vacuum diagram most of the cars have a sticker whit a vacuum diagram under the hood..if not look it up on line ..but to me looks like a hose for windshield wiper pump..
