Coolant Questions
I have a 1999 F250 with green coolant. I need answers to the following before I start my maintenance project:
1)I have green now and have never done anything with it. I am going to drain, flush, and refill with green. Is this OK?
2)If my vehicle is STOCk, it will NOT have a coolant filter on it correct?
3)What is the difference in the GREEN and GOLD coolant? Is one better than the other?
4)When I put the green back in, do I use ALL GREEN or do I have to mix green and some tap water?
Thanks everyone!!

Gold is good for 100,000 miles and you don't have to put any additives in. You MUST do a complete flush if you go with gold, I think there is a tech article here on how to do it.
A coolant filter isn't a bad idea, dieselsite for 80 bucks.

1. Yes
2. Correct
3. The gold is an extended life coolant. It last's 100,000 miles and does not require the use of supplimental coolant addative like the green does (like Steve_250 said).
4. Mix it 50/50, but use distilled water.

Rotella Diesel ready ELC costs the same as the yellow stuff, and lasts 6x longer without SCAs, with the exception of a booster at 300,000 miles.
A finer coolant doesn't exist.
You can get it at NAPA.
FWIW, even the cheapo stuff at Walmart will make the 100,000 mile mark (but you have to add sca's).

Elc
Rotella ELC in my y2k 110k miles, haven't bought any SCA since 55k miles!! You GOTTA do a complete flush if you change to an ELC. Pull the block, wp drains, and flush untill completely clear. Add your Rotella and you're good to go for longer than you'll keep the truck. 
BTW!!!! Make darn SURE that GM or some other oil changer doesn't add any 'universal' coolant or you'll contaminate the whole thing and need to go back to adding SCA's again!!!

orange is not to be used. most orange coolants are dexcool . also rotella elc costs 16.00 a gallon here and the regualr green costs 7.00 so i just use the green and change it every 2 years.
