[W126 Coupe] PAG VISCOSITY FOR NIPPONDENSO 10P?

[Steve Nervig]

Good enough, Dick. As you say, I would think that the pressure is the  
best measurement, as pressure change is how the system works. But I  
would also think that the systems would be more chassis dependent  
(length of hoses, volume to cool, etc), than engine dependent (mine's  
an M104), but I'm just guessing.
