For Gasoline Engines:
Non-pressurized: (or low pressure, i.e. 4.0 psig) decreased leaks, lower pressure parts, decrease of thermal flexing or cycling (component life extended), elimination of accidents resulting from accidental removal of radiator caps from hot engines.
Allows for a totally closed system (Hermetically Sealed) requiring no service checks and is not subject to contamination.
Improved stability of engine operating temperatures.
Improved aerodynamic styling. The radiator no longer needs to be higher than the engine and can be placed anywhere.
Weight reduction possible if higher coolant temperatures are used. Smaller radiators, less coolant, light-weight metals (such as magnesium for engines), small cooling jackets in the engine, smaller fans.
Decreased duty cycle of coolant fan for the same coolant temperature by allowing for higher temperature excursions for short intervals with no adverse effects on the engine.
Faster combustion chamber metal surface warm-up, CO reduced in start-up (liners get hot faster) mostly because of lower specific heat of cold NPG.
Elimination of premature spark plug failure and head cracking by better cooling of head.
Reduction or elimination of pre-ignition and detonation:
Reduce head distortion and cracking at high compression and supercharged / turbocharged boost levels.
Reduce head gasket fire ring failure.
Reduce piston dome and ring failure.
Reduce valve face sinking ("tuliping").
Reduce rod bearing failure (caused by cylinder pressure, detonation related, spikes).
