Making it complicated - just drain out of the radiator until it's clear. No need to remove anything else unless you want to replace the thermostat and/or the gasket. The green anti-freeze is still made but like all coolants it now contains a bitter-ant to try and deter drinking by animals. Even disconnecting the hoses are really optional - I did them to ensure I could do 40/60 mix of coolant/water.

 

Read my post above

 

I agree they are getting too deep into it. What I always do is; Just open the petcock on the rad, drain the water, turn on the heater to run it through the heater rad, drain the primary container, run a hose in the rad for about 15 minutes with engine running, let drain, close valve and add coolant to what I think will be about 50/50, fill to top with water. (my sequence might need adjustment). We have some of the best water in the world here at Mt. Shasta but I'm thinking the anti-corrosion properties in the gold might remedy harsh waters elseware.

Really? The manual for my 2001 says "use Ford Premium Engine Coolant (green in color). DO NOT USE Ford Extended Life Engine Coolant (orange in color)." It doesn't mention yellow at all.

It says the V10 needs 27.0L (28.5 quarts).

 

Same here on my 2000. His information is incorrect for earlier models.
The green stuff works fine, you just need to replace it sooner. I'm fine with that.

 

Because the Ford "gold" (which looks yellow) wasn't put into use by Ford until 2002 model year, so your 2001 manual wouldn't address it.

The "orange" your manual refers to is the coolant Ford used in the '99 - '02 Cougars.

The "orange" is not the same as the Ford "gold" (Zerex G-05) coolant.

Don't be so quick to dismiss the use. A lot of people used to argue the OAT Extended Life Coolant (red in color) shouldn't be used for the late 1999 model year (MY) and up 7.3L PSD engine, but they were wrong.

On another forum, there was a moderator who always argued with Gooch (a coolant expert) about the use of ELC in the late '99 - '01 year diesels, even though International (who made the engines for Ford) changed some things on the engine to make use of ELC compatible, then recommended OAT ELC for the engines.

Early '99 7.3's should still use the conventional "green" coolant, but from MY late '99 and up, ELC is the best coolant that can be used, even though the manual recommends a conventional "green" coolant.

I'm not advocating the use of the Zerex G-05/Ford "gold" coolant in the early gasser engines since I haven't studied the proper coolant use for those engines like I have the 7.3L diesels, I'm just saying don't be quick to dismiss the idea until you've done your homework.

EDIT: A quick search and some research indicates Ford DOES advocate the use of the Ford "gold"/Zerex G-05 coolant with Excursions that came from the factory with the conventional "green" coolant. So ComputerCowboy was NOT incorrect with his posted info.

 

Thanks for the clarification. I bought some Zerex for a Grand Caravan I used to own, and had heard that it was being used by both Dodge and Ford, but wasn't sure since this manual didn't address it. Regarding the Gold (yellow), even the fordparts.com site says this (emphasis mine):
I did finally find this document that seems to support what you've said:

http://www.fcsdchemicalsandlubricant...ref/scucEN.pdf

Currently the tank is green and I have no idea how long it's been in there, so now I need to decide whether I want to keep the green stuff or switch to yellow.

 

Not to split hairs, but that document doesn't seem to support my post, it specifically supports the info I found last night on the 'net...while half asleep, LOL!

He was talking about a V10, as was I. For a diesel I would use ELC.

 

You need to re-read my post. I used the diesel's to illustrate a point.

I know you and he were talking about the V10, that was clear. Just as it was clear I was posting a response to your assertion that using the Ford "gold" for the V10 was bad info by ComputerCowboy, when in fact it wasn't bad info, but was spot on.

Stewart

 

Computercowboy claimed the v10 is supposed to use the gold stuff.The earlier Excursion models didn't come with the "Gold" stuff. The manual even states to use the green stuff.

 

Like I said, re-read my post.

The "gold" wasn't in use by Ford back in 2000/2001 so naturally your manual WOULDN'T address it.

But now, Ford DOES recommend you fill the V10 with the H-OAT Ford "gold" (Zerex G-05) coolant.

Great discussion, I was not sure about the rear heating system draining, refill, purge. Thanks for the information.
