Best coolant

What's the best coolant for my 7.3? Seems like my truck just drinks it faster than I can fill it

Good - Ford Green
Better - Ford Gold
Best - Aftermarket HD ELC (Usually Red)

For the record, I dont recommend Ford Green, and recommend the ELC, but gold will do.

Also, if your truck is drinking coolant, the last thing you want to do is waste money putting better (more expensive) coolant in. Get it fixed.

Also, you should note, colors dont matter outside of Ford. Ford uses colors to distinguish their coolants, but a Ford Green and another manufacturer (eg, Prestone) are NOT the same. You should not be running any coolant that is labeled "All Makes and Models", "Mix with any color", "Any Vehicle" etc etc...

You neglected to say that you shouldn't put Ford Gold or any other ELC coolant into a truck not designed for it. If your truck came with green, stick with it. The seals in the front cover were updated for ELC as it reacts to the older sealant

I didnt neglect to say that. I chose not to. I have never ever heard of any e99 trucks having issues with gold or ELC coolant, and I have seen several run it.

Also, T444Es were run with ELC, including their 99 year engines. Sooo... Dont run it if you dont want to. But until I see actual evidence, I will stick with ELC as my recommendation.

Check the weep hole on the water pump. Could be loosing the coolant there. Hope so, otherwise you may have other problems. Fix the leak first. Check the overflow (de-gas) cap for proper pressure. If it's weak you could be loosing it there, but that will probable show as a full overflow bottle and you'll be able to see it leak out the relief hose. You'd probable smell it too. If your pump is bad you'll be able to smell it there too. Otherwise it could be a head gasket. I don't say that to scare you, but it's another possibility. That should be easily found, look at the oil. If it looks like chocolate milk... guess what?

I run Zerex in the white jug in my 7.3L and then just add the Fleetguard DCA4. We sell a lot of the Fleetguard Lifetime coolant too, but I personally put in what was intended for the system. I've had no problems other than having to replace the water pump a year ago.
