fitting/ valve "service use only"

[teamjp4]

There is a small valve that says for service only that comes from the radiator to the water pump. 3 radiator hoses attached to it. I broke that small fitting and jury rigged it with suction connectors to work. I do want to replace this. WTH is this? I could post a pic but if anyone knows, please help. The fitting broke inside the hose so now it's flushed with a hole in it. I stuck a suction fitting in there and sealed it but it looks tacky. I want to replace this.

I think you may be referring to the Water Crossover Assembly which contains the engine air bleed valve. I've pasted in an image from the service manual. Does this look right? If not, I would suggest you attach a photo of the valve in question by uploading it to a photo sharing service and pasting the link here.

Looks like the engine air bleed on the gen I V6.
