What is it? It's part of Cooling System.

[TenorJules]

Hi

Hope I can describe this. The hoses that run to and from the thermostat then connect onto the pipes that run to the radiator and back again - In the middle of these hoses there's a black plastic 'thing'. Four large hoses join onto this 'thing' plus a smaller hose that also looks to be part of the cooling system. It also has something that can be turned, I don't know what this does. My black plastic 'thing' is cracked and I need to replace it. I triend to post a picture but it made this post too large.

I know what you are describing, it it the middle of the pipes that run across the rear of the engine bay.... Ive read threads on here before where people vastly more knowlegeable than I have said you cant get them new anymore, so if you need ne you would have to either repair, or source from a breakers. The 'valve' turning bit you described is a bleed vent point. but even if you do away with this 9and some have had to) you can bleed system in other ways...
Keep us posted.

vw call it a junction
it depends which year and engine and weather there's a webasto heater or not as to which one you have but they are obsolete from vw so you'll need one from a breaker that matches yours

thanks, at least i feel like I'm getting somewhere now. I'd thought about repairing it but as it's a presurised system not sure what to use.

[billy739]

you havent filled in your profile, or details of the van but i guess its pre 1983 , v,w,x,y,a or early b registered petrol?

It's my best guess at

In the middle of these hoses there's a black plastic 'thing'.

It's where one side of the front > back and heater hoses join up, it's secured to the front of the engine bulkhead on the later cooling system.

Crystal ball goes back in it's box

I wonder if we are talking thermostat housing assy here ?

Good fun this "I'll guess that part in 2" game

E D I T = Oops, no that doesn't have 4 large hoses on it as stated in the O.P.

Is this the part you need ??
Located on large hoses between thermostat/water pump and pipes to radiator and one smaller hose connector.
Hose stubs are for about 1 1/2 in (38mm) diam hoses.
This is off early type cooling circuit, 1.9 petrol
I have one spare and For Sale. no cracks and the bleeder (!) knob is not seized.
The cruddy appearance looks to be from underbody sealer by a previous carer!

Thanks to those who replied. This was the first time I'd used this forum and it's absolutely brill. I'm sure I'll have another question soon.
