Coolant hose bleed union - broken pipe

[andilad]

Hi,
So I have snapped the small pipe which comes back from the large union which joins the four coolant pipes behind the engine on a DG Early

Unfortunately, I'm also a Auto, so the replacement union needs two more pipes to the box; and these are not available!

I have posted in the Wanted for a spare, but I wanted to ask the wisdom of the forum, for if I can jury rig it, as the part search seems like a long one, and I need to move the vehicle in the next couple of weeks.

In essence, I'm wondering if I can block off the hole on the union, and terminate the pipe it feeds to; what would be the impact?

I'm not clear what this would do, the pipe is small bore so feels like it is going to be mostly a high point for the bleed - but could easily be wrong?

Thanks in advance!

I'm assuming you mean the early water system ?

85 could be early late , or late early .

Hi, yes early water system..

So that link is the right part for the system if the box was manual.
Brickwerks don't have one for the Automatic..

thx

Cast metal ones available in the US, should end up here at some point. As a bleed point, I never found it much use to be honest.

Yep that's a lot of money!!

I think I have fixed it up today, used a 6mm to 4mm reducer pipe and hope it might last long enough for me to source a pre-loved one at a better price.

But I'm really wondering if anyone knows the purpose of the small pipe, is it a high point for air to bleed or is it actually making a functional water circuit? as it is such a small bore, I'm thinking it is air ??
