Default Check your heater hoses O rings for leaks!

Dear Forum,
I have been trying to track down a very slow coolant loss for ages. Found out it was the o rings in the plastic connecters between the rubber heater hoses and the metal pipes? Grab the rubber pipe by the metal connection and pull it up and down...See if you get anything? It runs UNDER the metal pipe and drops onto the Catalytic converter, then the underbody tray and then gets pushed out of the back as you go?
Might help someone, sometime?

The O rings flatten and harden but are replaceable with care.
You can get them from China now-the Norma couplings I mean.

Just imagine a war with China:

What's wrong with your tank Smithers?
It's thrown a track Sir and Mr Wong's on holiday
so I can't get the part.

China produces engineers, while we produce lawyers, glorified liars.
Were getting our asses handed to us, & we wonder why.
