Antifreeze question

[55gasser]

thinking about changing the antifreeze in my 05 6.0.

Can i use a good antifreeze from auto zone or wal-mart or do i have to use the dealer brand ?

thanks for your help.

you can get zerex g-05 i got it at napa but thats about all u can use other then motorcraft gold

The only other thing you can use is if you want to get the best stuff, go with CAT ELC coolant. Its red in color, its NOT dex-cool. Its 500k coolant that is specifically made for diesels. I think the CAT, fleetguard, and rotella brand coolants are all the same. You just have to make sure you flush out all the old gold stuff really good. Otherwise yes the zerex G-05 stuff is what will work for an OEM replacement.

If you're gonna flush it make sure you use the motorcraft vc-9 flushing agent. You need 2 quarts. Drain the whole system including the block. Pour it in with water and run it at 1500 rpm for an hour, drain the entire system again, flush it out with water until there is no more flushing additive. Then fill with half system capacity of straight undiluted coolant and top off with water.

Yes they can be mixed.

The question to ask is why on earth is Ford using the same coolant in their Escape model vehicle?

[dieseldan2005]

From what i gather they didn't want to have different coolant for different models (saving money). So they just went with the G-05 based coolant in everything. This is not a diesel specific coolant though. Thats why i recommended the CAT ELC coolant. Its specifically designed for diesel engines and its supposed to last up to 500k. We have over 350k on both of our semi's with C15 cat engines with this coolant and there is no signs of any breakdown or contamination.

Exactly!! That;s why I'm switching to Fleetrite ELC when I install my turbo and intake manifold.
