Leaking heater pipe at thermostat - Your way?

[greasemonkey]

Hi guys

 

Still plotting along with my repairs at the moment. Progress is when ever I have the time. Stuff with cars takes longer than you allow it too!

One thing is that I noticed the metal pipe outlet at the thermostat is leaking. What is the best fix for this?

 

 See the picture (circled part) as a reference.


 

 Anyway I've researched and there is an o-ring that sits in this bugger however there is no mention to use RTV sealant. I pulled some off that was old and that is why it's leaking (clever me)

 

Any help appreciated as always.

just unbolt it and have a look if it has an o-ring or a gasket and replace as necessary.

The o'rings go hard over time and leak slightly. With a trust 10mm socket, undo the retaining clamp, pull the tube out, remove the old o'ring, clean the pipe and the hole it goes into, give the new o'ring a touch of silicone spray to help it slide in, do it back up.

I'll get a new o-ring then. Hopefully they don't require any sealant after installed (it doesn't leak).

 

Thanks Puff and Keith for the information.

They don't need sealant. Just make sure there are clean surfaces for it to seal against.
