i gonna drain and flush my radiator and engine in AM and replace antifreeze /coolant. what is the best product for the price?

Is the motorcraft coolant the only/best option?

Mod (Ret.)

Ask yourself: What antifreeze got the truck to this point without issue?

Then buy the same product.

I've stuck with Motorcraft Gold Coolant. If you have an 5.4L-get 3 gals-it will take all of it but 1qt. Just changed my this past fall, working great.


Be sure to use distilled water, not the garden hose.

Did you use 50/50 mix?

FrozenTundraGuy

No, since the block was full of distilled water, I just added the antifreeze, started it up and let it mix. I had to top it off a little bit both times. It worked out fine and is easier than taking the drain plugs out of the block to drain it.

Zerex G-05 is what I use in mine. Same as the Motocraft Gold. Different label

FrozenTundraGuy

Don't know about it being the same, but it is very hard to find in my market area-so I stuck with Motorcraft which is readily available.
