If I remember correctly, cold was supposed to be at the top line. I may be wrong, but I know it wasn't complicated anyway.

Since liquid expands when hot, the level will be higher when its hot.
With the cold level midway between min and max, the engine fully warmed up on a hot day leaves the fluid level at max for me. My truck has no overheating issues and runs dead center on the temp gauge.
Common leak points (if yours is going down and you have to keep refilling) are the thermostat housing, the heater control valve (mine is a brand new carquest brand from advance auto and leaks very slowly- get the motorcraft replacement), the water pump, and the stupid coolant tee beneath the intake manifold (PRAY yours isnt bad because its a nightmare to change that hose).

Re: The "what do you hate about your Ranger today" thread
That's right, I did fill mine after driving a little while, up to the top line.
Thanks for the correction.

The way I see it - as long as there's a coolant supply to the feed at the bottom of the tank, it shouldn't matter how much is in it. Min or Max the truck has plenty of coolant.

I remember hearing something on these forums about the fluid level should never be below the level of the cylinder head. Considering it has a water pump and the bottom is the feed, I dont see how this makes sense- the coolant is getting pumped through the head by the pump regardless of how low the reservoir is (as long as fluid is available at the feed).
I could be wrong, but im inclined to agree with you.

I have the 4.0 sohc and I have 1 cold fill line. When the engine is cool and not running it should be at the line(which is really hard to actually see because its on the bottom half of the reservoir blocked by my air intake haha

Yeah the whole system is under pressure anyways, "Great idea, Ford"
It may not look like it, but the whole tank is above the head anyways for that reason - so idiots don't crack the head when the tank runs low. At least a few inches. And if you noticed the little coolant tube that supplies the tank runs from the feed to the heater core, goes up sharply over the AC compressor and then sharp back down to the tank to prevent any air from going back into the system. Ford did pretty well designing this engine.
Just wish they didn't have a 3 quart oil pan or a water-cooled transmission. *sigh

Boiling point is higher under pressure. Not sure I get your point. And what do you mean by water cooled transmission? If it is an auto, it has a cooler, so it will live longer.

Oh I see what you mean, I was telling GSF1200S that the tank level doesn't matter, it's pressurized.
But yeah on the Duratec models the transmission cooler lines go into the radiator, get cooled by the coolant and return back to the tranny. No auxiliary cooler.
Not to mention both the damn cats are an inch from the tranny pan. Its not hard to overheat the trans on this thing, I've done it once before just by driving up a steep hill at 4,000 RPM

Re: The "what do you hate about your Ranger today" thread
Ok. But I thought EVERY auto went through the radiator, and only special packages had an aux cooler, that was in addition to passing through the radiator.

They might but I'm not sure. I can check my friends 4.0 Expo, she has an Aux cooler but I'm not sure on the radiator.
I just think it's not efficient enough, id like to keep the trans temp down but the factory set up doesn't allow it to be as cool as I want it.

Hey guys, what is the consensus about running 93 non ethanol fuel in the 2.3. A friend told me that it might not be good for the engine to run 93 octane fuel.

It's just throwing your money on the oil company. You get nothing out of doing that.
