Gunge in Header Bottle

[Mark Ferguson]

Had the HGF late last year & just putting everything back together & still got some residue in the header.

1/. Is it ok just left in there or

2/. What is best way of getting residue off sides & flushing it through.

 

My header bottle is the square shaped one.

 

Thanks Fergie

Is this hard residue?

 

Scaley deposits?

 

There was a thread or two about this around 18 months ago.

 

I must say that I tried all of the options suggested (various chemicals, filling the bottle with stones/nuts&bolts and shaking for hours on end etc.)

 

In the end, I gave up. It's still there - doing no harm whatsoever if the current coolant can't budge it...

I got fed with thinking the head gasket had gone, everytime I took the bonnet off, and seeing gunge in the bottle. I used one of those bendy bottle brushes to clean mine. Worked a treat.

Same as Myles and Ozzy - I tried everything, even resorting to sticking it in the washing machine!

 

In the end, I cleaned the deposits away with a soft toothbrush.

Take off the header tank.

 

Plug the hose holes

 

Fill with hot water and some detergent or a dishwasher tablet and a handful of ball bearings or washers or ,m6/m8 nuts.

 

Fit the cap

 

Shake vigorously for around 15 minutes in various different postions.

 

drain the contents.

 

voila, cleanest clean you've ever been.

 

works every time.

If this is a bit too hard or boring then just wipe your finger round every so often till the gunk is (mostly) gone.

I put petrol in mine and shake it around for a few minutes - seemed to work well.
