Here is the coolant sample Im sending to Ben for testing.

The sample is shaken not stirred!!!!! It does settle out to a semi red OAT colour with 5mm of sludge at the bottom of the bottle.

CAT analysis.
Mo455,P<1,B<1,Glycol36,NO2 268,Mo04 728,K<1,Na2949,BO3 0,P04 0,Si03 20,Odour -,Oil -,Foaming F,PH 8.9.Cond 3383.

REPORT.
URGENT. The Iron is Extremely High.The glycol level is slightly low.Some foam is visible in the sample.Drain,flush several times with clean water and refill the system with new coolant.Resample afterwards to monitor.

Thoughts people,we have already done all the flushing/new coolant etc,even dropped 2 lots of new coolant after due to turning black,has 100% CAT ELC coolant at the moment.

Andrew,you may get a phonecall from the boss asking you to put into words what you think your prognosis is,we need to get rid of this grader before it costs us bigtime.An independant opinion will really help,will get Tony to cantact you.
Ben when you get the sample,Ive asked them to put the shire Email addy in the info.Could you please send you results/thoughts to Tony Kett.

Its parked up at the moment having a rest as its not needed.

So can I send the bill to council then???

No probs. Bit darker than I expected though. If you have a strong magnet, run it alongside the sediment and see if it pulls anything out. This would indicate possibly a porous block.
Something definitely not right.

Did it go cloudy running rain water?


Sent from my backyard TeePee using smoke signals.

if it keeps on doing it that quickly its got oil contamination.

No oil detected in the sample.Oil floats on water,it wouldnt settle to the bottom of the bottle.
The sludge dries to a coarse sand like texture,its not oil.

Sample should be on the way to Ben.
Never went cloudy with rainwater,was black the whole time.Only takes hours to turn the coolant from red to black.

If a bill is needed send an invoice to the shire with the results
More than happy to cut the bill out with a firewood trip/homebrew evening
