antifreeze

[barnaclebill15]

Changed my thermostat about 3 years ago and needed to add some antifreeze so bought some from the dealers, I am sure it was blue.
Checking levels today, the coolant looked a little low so before topping up looked in the header with my flashlight and it looks slightly orange.
Confused now, sure what I used before was blue, still have the old bottle but the label has come off.
Have not had any work done by the indy on the heating so can not account for the colour change.
Any ideas

Colour is nothing but a dye and there is no standard as to what each colour is.
The correct coolant for most MBs is Comma G48 (green/blue usually )but if you don't know what's there already do a full flush with plain water and refill from scratch.
You cannot mix the various types as they can form a gel (and that does nothing for cooling).

is that a bit like a torch?

Sorry, three years training foreign engine cadets so need to use words they understand, spanner gets blank looks as does torch and all pressures in Mpa and kpa.
Cause problems saying thousands of an inch then tell then 1mm is about 40 thou so 0.1 is about 4 thou.

Removed a small quantity from the header and it is blue/green when viewed in a clear plastic bottle but in situ looking into the header it is red/orange, must be the colour of the bottom of the header.
Well problem solved just get another 325 from the dealers.
