Hi everyone,
Replaced the thermostat the other day and got everything back together alright, no leaks or anything, but I ended up with only 1.5l of G12 and mixed that with a gallon or so of distilled water to fill up the coolant system as a temporary fix. Picked up a gallon of G12 today, want to get the mixture right. Do I have to do a complete drain, and do a pre-mix to ensure my 50/50 blend? What is the quickest way to do this? It seems like most of the G12 hasn't cycled up into the coolant expansion tank (which is mostly water with some G12 mixed in). I originally put in a 50/50 mix, then topped off several times with distilled water. Knowing this, is there any point I can drain which would retain my 50/50 towards the bottom or do I have to re-drain completely again (was kind of a pain in the butt to do the hoses from the oil cooler and the lower intercooler pipe).
On the mixture, I know my owners' manual recommends not less than 40% and not more than 40%, and most tutorials will recommend 50%. The detriment of too little being corrosion and not enough of a cooling effect? The detriment of too much being...? Too viscous? I've read that some will increase the water in summer months although this seems silly.
