Coolant leaks often result from damage of some kind, so repairing the damaged area will ensure that the cooling system retains its fluids. Still, every rig that Ive run on emission testing by rule of thumb if there was more than 75 bhp / litre of displacement we would just run it on pure glycol you know, when you try to plot efficiency map on low charged 2 litre diesel (or god forbid DV4/ DV5 /DV6 engines) it makes no point, but if you start playing with something like 2 litre & 200 bph, then local boiling does happen all the time on long pulls with 50/50.
