Martin; if
Rad-Fix is "non clogging" and "can be flushed out" then how can it seal a leak in the long term? Think about it.
The second point about products like that is that they do not eliminate the problem, they "paper over the cracks".
The third point is that they're designed for completely non-technical owners which you clearly are not.
Removing the heads will be a waste of time and a lot of money. You will not have head gasket failure on a KV6.
Have you ensured that the two plastic clips on the straight pipe in the 'V' are both pushed
fully outwards so that they are in close contact with the water pump and thermostat housings? A small leak in the 'V' can evaporate leaving little trace.
Renewing the flattened 'O' ring seals on my original expansion tank cap made a big difference. Have you done that?
