99 F150 4.6L coolant

[DieselTech]

Hey guys I have a 99 F150 with a 4.6 in it. I'm looking for opinions on which coolant to use. It's time for a flush and new hoses.

Thanks for your input

I have a 1997 4.6 and use Peak Global for the past 100K. The yellow stuff still looks yellow. I have never done an analysis. And I too am due for a flush. I will use Peak Global again.

I have been told that original low silicate green will work the best. So I'm thinking of going with the Zerex original Low silicate, zerex Super flush, and adding a small bottle of Zerex conditioner and lubricater to the coolant fill.

Looks good to me.

Well I flushed it last night. After I ran the flush through it took me almost 2 hours worth of flushing to get the water som comeout clear. After I shut the hose off I ran 3 gallons of Distilled through it to get the Hose water out. Then filled it and added the Additve I bought. After driving arounf today I looked at the coolant and it looked Great!!
