I am looking for a cooling system part for a 2011 Cadillac CTS V Coupe. I cannot find the part on any engine diagram on the web. It is located near the oil fill cap. I have attached a picture of the part, circled with an arrow pointing to the failed plastic elbow. The elbow includes some sort of in-line valve (?) that connects to a steel line. The steel line goes into the engine or head base and is held in place with a bolted bracket. I do not know the function of the valve, or even if it is a valve.

Hopefully this will help identify the part. Your help will be greatly appreciated

Isn’t that the steam vent port? I just replaced mine with Motion Raceworks steam port kit

I'd be very interested in seeing your install. Any photos you'd care to share? I've been looking at the Motion kit.

Did you "unplug" the rear steam vent ports? I'm curious how you routed the hoses.
