Stock is 190.4. The "hot" aftermarket one I found is 192

Typically AM does not have the sub thermo and warm the car up slower, even if they will maintain a higher temp. Which is OK for the application I suppose.

Heat capacity is largely a function of temperature, not pressure. So changes in pressure will have very negligible effects.

Running more anitfreeze and less water will reduce the heat capacity of the coolant.


EDIT: From thermo 1 book, enthalpy for water

at 100*C @ 10kPa = 2687.46 kJ/kg

at 100*C @ 50kPa = 2682.52 kJ/kg

For a loss, of 0.0018%. Tiny, and pressure hurts heat capacity, not helps it.

Upper hoses are smaller so the pressure is in the motor and the pump sucks from the radiator avoiding the above mentioned problem. The pressure were talking about here is not pressure from heat, its the current pressure from the pump.

Yeah uh... about that. I don't know what car you are talking about but the inlet and outlet of my radiators are both 1.25".

actually, the water neck from the rad to the pump is the bottleneck of the system in our cars. However, I also discovered that this lower pipe follows the required shape for a coolant reroute, so I'm using it for a hard-pipe instead of the rubber ****.
