Volvo plumbing connections?

[RobWales]

I notice that the rigid pipe connections on my volvo AD41's have no visible means of a threaded connection.....

i.e the pipe from the top of the thermo housing to the intercooler and the pipes into the aftercooler (cac) just seem to push in ?

Could anyone please enlighten me as to the method of sealing of these rigid connections? are they just push fit with an o ring type seal perhaps?

Thanks

Don't know the AD41, but Volvo certainly use push fit with O ring connectors on other engines. The rings are the cheapest Volvo spares at a few pence each!

Thanks SS,

I'm guessing then that the 'o' rings sit within a groove/undercut on the inside diameter of the mating flange?

If they are a push fit connection they will have a little plastic collar that slips around the pipe and then held in place by a retainer and an "O" ring. Before fitting clean metal up with some fine wire wool (so nice and shiny) then a good blob of silicone grease.

I have some manuals on pdf for the AD41 if you havent got them already. And a Parts manual if thats any help. Just drop me a line with your e-mail address and I can forward it to you.

Yes, there is a lip for the ring in the female pipe section.

Yes, it's a bloody abortion. Just one little bracket in the middle, holding it on. If it's leaking, about all you can do, is clean up the ends and put some vasaline on the O ring.

Yep
All received Chris, I emailed you by return.
Great info and many thanks again.
Rob.

That particular pipe is "O" ring sealed and the pipe is held in place with a large "P" clip.
