Why Does Your Vehicle Need a Coolant System?

The cooling system takes care of the highly inefficient combustion process that wastes the majority of the energy from fuel by way of heat instead of horsepower and torque. Only 30-40% of fuel burned is turned into mechanical power the rest turns into heat and you need a system to deal with that.

The big issue with coolant is where to dispose of it safely. Please don't just dump it down the street!! And dont even let it absorb into your skin. It's bad stuff!!! But the Amsoil Heavy Duty version has stopped my over heating in my Ford 390! Yes Sir!

What type coolant for those inverter systems and what is the frequency of changing it out?
