Fixing things started with a new grommet for the cable of the phamous phlap:
The old one was deteriorated and allowed water ingress into the passenger footwell.
Then I rigged up new plumbing:
I cleaned the expansion reservoir, which was smack full of brown sludge:
I then flushed the entire cooling system as good as I could. This is what the water looked like when I deemed it
I then strategically placed four dishwasher tablets in the cooling system and put everything back together.
Not wanting to waste any expensive antifritz, I filled the system with water only and meticulously followed the
bleeding procedure outlined in the manual.
Note: R16s must be bled when the moon is between half and three quarters after the August Bank Holiday Weekend,
when three witches meet at the crossroads and the neighbour's black cat just walked through your garden.
Anyway, I let it run until the fan came on, went off again, came on again, went off again. So two full cycles.
Nothing untoward was observed, so I'll keep the dishwashertabletted water in until the weekend, then drop it and
refill with proper stuff.
That should be it.
Well, it must be, because I'm not going to take off the scuttle again.
To reconnect the cable for the phamous phlap is such a dirty bitch, it almost drove me up the wall.
Anyway, this is what the water looked like after having it running for ca half an hour:
Not half bad, is it?
