Thin layer of gunge in coolant tank - should I be worried?

[Neil_K]

I have what appears to be a thin layer of slimey gunge (colourless) in the coolant bottle on the flat section below the inlet pipe. Not wanting to instantly jump on the HGF band-wagon, is it something to be concerned about? Inside of cap seems OK. Could it just be manky old coolant?

 

Engine is not particularly old (in miles terms) and always driven with consideration for temperatures etc - whether that makes a difference?

Have that in mine, always have. I wouldn't worry

Watch out, whatever hits the fan will not be distributed evenly

The coolant system is where all the pixies and gremlins hide... hence the slime....

VX's always make the expansion tank brown but it usually goes no further.

If it's a K and the coolant level has been low for whatever reason keep an particular eye on it, and particularly if overpressurising / water loss.
