Hi all and happy new year, does anyone have an opinion on waterless coolants,and if this would help these problems ?

Waterless coolants have a higher boiling point and would help. The main reasons for overheating basically come down to: Blockage, Malfunctioning/Incorrect Parts, Cavitation and Air Flow.
Cavitation is air in the system as a result of not being bled properly (fill point or bleed hole should always be at the highest point of the cooling system). An impeller rotating too fast can be detrimental. I.E a incorrect water pump pulley.

Things to check:
Thermostat opening at correct temperature.
Thermostat is not installed upside down.
Water disappearing under higher revs with radiator cap off. (Hold revs and fill, replace cap)
Hot spots in radiator core - blockage.
Open heater taps when filling radiator and bleeding system.
Water in engine oil? Blown head gasket, cracked head.
Leaks.
Steam out exhaust pipe - Blown head gasket, cracked head, manifold corrosion, crack or gasket seal fail.

A radiator cowling (like a thermo/engine fan) only work at lower speeds I.E in traffic. Open road air speed will surpass cowl and fans.
