Where can you find a free schematic of 2000 Ford Explorer coolant system?

Answer I seriously doubt that such an animal even exists, let alone for free. There are certain basic things like cooling system operation and componet function and location, that vehicle manufactures assume that those who work on vehicles, know and can figure out. Quite frankly a cooling system is one of the most basic things and is pretty elementary, and really doesn't need what you would call a schematic.

The flow is simple. Radiator to lower hose, to water pump, to engine block, to heater hoses, back to block, to cylinder heads, to intake, to thermostat, to top hose, back to radiator. That is a cooling system in a nut shell.

That would be the only thing that could be laid out in a schematic, order of componets ad coolant flow. If you are having a specific problem, if you post what that problem is specifically, maybe we can help resolve it here.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
