water level should be to the water level indicated on the recovery tank when the engine reaches operating tempature.
Look real close to the side of the reservoir - you'll find very hard-to-see level markings: "Full Cold" and "Full Hot" (or similar terms).
Those are your level targets when topping off the coolant.
There are illustrations and instructions for your specific model year in the Owners Manual - along with anti-freeze specification. (See "Related Questions" below for free online copies of 1996 and new Ford product Owners Manuals!)
This is also a good time to think about how long has it been since the anti-freeze was changed.
If it is brown or otherwise discolored, you should seriously consider having the engine flushed and filled with new coolant.
See "Related Questions" below for more about radiator draining and flushing...
The coolant level is set by the level in the coolant reservoir. There is a line for the level if the engine is cold and a line for if the engine is up to temperature. You should fill it to the corresponding line.
In the coolant reservoir when the engine is cool.
Most vehicles have a coolant reservoir (a clear plastic tub) with a phrase "engine coolant only" printed on the cap. This is where you should add engine coolant.
Yes , on my 1995 Ford Explorer XLT there is a cold fill mark . When the engine is cold the coolant level should be up to the mark
Yes , mine has a cold and hot mark , the coolant should be up to the cold mark when the engine is cold
When the engine is cold it should be up to the cold fill mark
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
With your engine cold there usually is a cold fill mark on the reservoir or there might be a dipstick attached to the reservoir cap that has a L or F mark
Looking into the engine, on the far right there is a visible coolant reservoir near the hinge of the hood. On the side of the reservoir closest to the center of the engine, there should be large markings for minimum and maximum fill. Given the bright orange color of the recommended coolant, it should be easy to see the level.
The freeze plug on a 1998 Ford Taurus is located on the front of the engine block. It prevents the engine from cracking should the coolant freeze.
There is no cap on the radiator; instead, the coolant reservoir is pressurized along with the rest of the cooling system. Look on the passenger side, under the hood. You should see the windshield washer reservoir AND the coolant reservoir. Be careful with the lid of the coolant reservoir. If the engine is hot, it will blow off in your face.
On a 2003 Ford Ranger : The 2.3 litre four cylinder engine has a thread on cap on the engine coolant reservoir , that is the pressure cap / radiator cap ----------------------------------------------------------------------------------------------------- On the 3.0 and 4.0 litre V6 engines , I believe there is a radiator cap on the top of the radiator , but with the engine cool you should add engine coolant to the engine coolant reservoir - it has a cold fill mark
