[Vwdiesel] Food color in coolant?

[Dave Cook]

Sounds crazy, right?

As you know, I've started driving my '78, TDI powered bus again after having installed the second motor.  At this stage in the game, I'm considering everything testing until I'm sure all systems are set up and working properly, etc.  

 
I'm waiting for the cluster to arrive from Brazil which will allow me to have the warning light for low coolant condition.  But I'm a little paranoid, so I'm checking the level anytime before driving for now.

Trouble is, the bottle is a little cloudy so sometimes, depending on the lighting, etc, it is a little hard to see the exact level.

So I was thinking of adding a little food color to the coolant to make it darker/more visible.  Once I'm satisfied that things are working properly, the system will be drained and flushed and filled with proper coolant.

I can't think of any reason this would hurt anything, but I'd like to see other's thoughts.  Perhaps I'm just being paranoid about missing it if I lost coolant again due to what happened before.
