Hi all, Many apologies if this is not the correct place to post this. Guidance gratefully received. I recently had a new radiator fitted by a garage on the Alphard, however, they forgot to transfer the oring from the old radiator where it connects to the water inlet. Slowly, but surely, water leaks over time now and I have to refill a fair bit to make sure we have enough in there. By the time I had realised what had happened, the garage had ditched the old radiator and don;t know what oring I should use. (I know, I know, not using them again, pretty bad really). I did buy an oring set from Screwfix, popped what looked to be the corrcet size on there and clipped it back together, but the leak still occurs. I attach pictures of where the oring should be, but can anyone help me discern the exact type I need? I would be most grateful for any help given on this. Thanks, Richard
