Coolant?

[fordtruckthing]

I'm sorry to ask because I know its been asked and there is threads for this topic. I've read threads and looked all over the internet and my head is spinning about what a suitable coolant would be to run in my truck. I could leave the topic alone and go to the ford dealer and buy there specified coolant #E2F2-19549-AA however I want other options. My current coolant color is green. There is a International dealer near me what would they carry suitable for my truck or other parts stores? Also planning on doing the coolant filter at same time and I understand what to do any final suggestions on that?

Thanks,

international harvester makes a concentrate that does not need additive. -no maintenance. I think you can add a booster and get you 300,000 quality miles from your coolant....

it's red and get the concentrate, not the premix.
use distilled water and flush your system well.

i was told a seemingly decent way to do the flush easily; without any flushing equipment:

drain from the radiator peckkock - will yield about 4 gallons.
add 4 gallons of fresh water (hose water)
warm the engine (i used the heater as gauge -when it blew warm the system had fully circulated)
drain another radiator full
add 4 gal. of fresh water
Warm the engine
-rinse and repeat until what you're draining from the radiator is clear and fresh (took me about 8 times)

at that point repeat the whole she-bang with distilled -draining and refilling 4 gal. at a time with warmup cycles in between. YES- i went through 28 gal. of distilled -cleaned out two grocery stores .

Add 4 gallons of the IH red concentrate - done! -you have your 50/50 mix.
I made up another 50/50 gallon to have in the truck for initial top-ups for the first few days after flushing.

note: sometimes air can get trapped in the heater hoses as they are the highest part in the system. if this happens, your heat will never blow warm, or will do so intermittently. mine worked itself out aver a day or so but, if air is still trapped, you may have to remove the heater hoses and prime the connections (both sides, heater core and hose sides) will some 50/50 mix

you could also pull the block plugs to get all 8 gallons out at once. i guess there are two by the motor mounts...
