Milky Coolant in the Header
 

Odd one this...

Couldn't see any blue fluid in the tank for a couple of rides.

decided today to get the cap off and look inside with a view to a topup.

Pulled the tank back and took off the pressure cap and there was a white viscos foamy **** in there.

I will drain and flush tomorrow. Have taken out the drain plug fm water pump and all that comes out is pure blue anti f.

I know when I had a replacement Gearbox 700 miles ago the mechanic admitted that the said tank had slipped into some oil and taken some on. He had washed it thru a number of times and has offered at next service to flush the cooling system thru for free.

Oil level is fine and a good dark brown colour.

Coolant from the pump is blue and coolant like as expected.

Top header tank is full of milk.

Like I said will drain and flush tomorrow and refill.

Any advice welcome

Cheers guys

Had the same problem, found that the water pump seal had gone.

flushed through about 20 bucket fulls today and topped up the whole coolant system with the right stuff - took her for a blast and thrashed it ......and still have blue in the header,,time will tell ........will see what happens in the next couple of weeks
