Citroen relay 2.0 hdi 2017 thermostat-waterpump pipe "O" rings

Unread post by dpround »

In my quest to fix the 5V sensor rail I have removed the thermostat from the side of the engine. Mostly it was pretty painless, but getting the thermostat-waterpump pipe out of the back of the thermostat was challenging. "Just wiggle it off" says the handy youtube video. It did come off, but required excessive force and a couple of crowbars, mainly because of the poor access but it was tight! I wonder if the "O" rings on this steel? pipe have swollen. Can anyone tell me what these "O" rings should be? Can they be bought as a part from a main dealer, or will they only sell the whole pipe assembly?

Any tips for reassembly? Lubricating with soap might cause other issues. How about silicone?

The "O" rings are available as a separate part, but they are £8 each, probably plus VAT!
