According to the 2004 Ford Explorer Owner Guide :
It came from the factory with a 50 / 50 mix of distilled water and YELLOW
colored antifreeze ( meeting Ford specification WSS-M97B51-A1 )
That really depends on WHAT MODEL YEAR of Ford Explorer My 1995 Ford Explorer XLT came with a 50 / 50 mix of distilled water and GREEN color antifreeze meeting Ford specification ESE-M97B44-A in its 4.0 litre Over Head Valve , V6 engine cooling system from the factory
Cylinder head where valves are-usually. Valves themselves, no. Antifreeze passes around the engine in special chambers known as galleries. It cools the metalwork of the engine and does not (or should not) enter any part of the combustion, or intake system.
Your 50 / 50 mixture of antifreeze and preferably distilled water should be right near the top of the radiator ( as long as you can put the cap on without the antifreeze mixture overflowing ) The plastic coolant reservoir in the passenger side of the engine compartment has a cold mark on it , just maintain your coolant level up to the cold mark when the engine is cold . ( Ford recommends to not drop below 40 % antifreeze and not exceed 60 % antifreeze in your engine coolant mixture )
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
According to the 2000 Ford Explorer Owner Guide : All the engine cooling systems came from the factory with a 50 / 50 mix of distilled water and GREEN color antifreeze ( meeting Ford specification ESE-M97B44-A ) * 4.0 EFI / 4.0 SOHC / 5.0 liter V8
Any antifreeze which is Dexcool approved.
No. Antifreeze should not mix with engine oil in any vehicle.
It depends on the fluid. Antifreeze is a different color from engine oil.
In the coolant reservoir when the engine is cool.
It should be a 50/50 mixture of water and antifreeze.
No , the engine should be cool before adding any fluids to the engine cooling system
