what type of coolant to use?

Hi gang, i just wanted to know what type of coolant does our 2001 4.6 e150 use? any particular type/brand? is it a 50/50 mix? i have "universal" (green) fluid i can use. I just want to gradually, "drain and fill" reservoir till it's all changed out. Is this a good procedure?
i looked at the fluid tonight, seems a dark orange color. I'm not sure if there was a git of oil mixed in there as well.
thanks
fab

Check your dipstick for any sign of water/oil mix, it will look milky, also under the oil fill cap. I would just drain/flush and change if you are concerned. Any 50/50 universal green antifreeze will work fine. If your loosing enough to have to keep filling the overflow, you have another problem.

Orange coolant is probably a sign someone added Dex-cool into the system.

Hey gang, well, I emptied out the coolant reservoir with (siphoned it with clear hose). I looked inside once emptied and was surprised to see a lining of black sludge inside the reservoir. Is this normal? If not how can I remove this? I filled it up with a 50/50 mix of green coolant. Thanks

Take the reservoir out of the van and fill it with hot soapy water. Shake it up. Then try to scrub as much as you can with a bottle brush. Then reinstall it and drain the whole system. Fill it with a couple bottles of cooling system cleaner and water. Drive it 2-3 days and then drain it. Repeat as necessary until water draining is clear. Then fill the system with 50/50 MotorCraft Green Coolant/distilled water.

I saw that if someone mixes dexcool with the green stuff it creates a sludge, I hope that wasn't done to yours, flushing that is a nightmare, will require thermostat replacement.

if they are mixed it makes "jello" in your cooling system
as said above, a nightmare
