My observation was that the pinky coloured O rings on the old parts, deffo on the straight pipe were badly flattened and came out very easily! After just 5k!! But black O rings seem to hold shape better. I also noted lots of silecone used in previous assembly, safety measure i guess? I took a long time cleaning all the housings to take the new O rings and used Molycote 111 as recommended in the plethra of previous 'Thermostat' posts! That made assembly easy.  Bleeding was easy and dare I say after a weeks driving all's good running generally around 89- 91degrees.
questions:
1. are black O rings original spec and if so are they available? 
2. Why are pinky coloured seals sold if they fail?
3. Does Kaiser (hope you see this Kaiser) still supply whatever it is thats made from metal? And if so what type of O rings are on it - or does the metal bit come naked? |
Black O rings are original spec, pink O rings have changed colour due to being in contact with a chemical that is red in colour.
The O rings have failed due to compression set
