Just overfilled the coolant / antifreeze reservoir...

... and the question is - does it really matter?

I know, I know, amateur night at my house. It's late, dark and I never really learnt the difference between 'jobs that can wait until the morning' and 'well, well, well, the coolants low, can't have that can we...'

So, it's gone from being just below 'low' to being at the top of the reservoir, well above 'high'.

So, you tell me PH, I am not in the mood for making decisions.

Leave it, it'll be fine.
Syringe the excess out before the car detonates in a ball of flame.

Thanks for helping.

I did notice that on the header tank cap, there is a pipe that goes into the reservior, but also little pipe that runs off from the cap.. Hence my thoughts that maybe it didn't matter as it'd squeeze out any excess that way. Still, won't take too long to dunk a few wads of kitchen roll in there to soak it up.
