Coolant Brand

I see here that the majority recommend ELC Coolant.

I am assuming that ELC is simply " Extended Life Coolant."

I also see recommendations for CAT 1.
I have also heard dont use the orange coloured one as it destroys seals.
have also heard dont use Ford Gold as it gels ( I know Bismic doesnt drink that coolaide)

There seems to be more to Antifreeze than meets the eye and a primer discussion on Antifreeze/coolant may be helpful


Can anyone provide a list of brands that are suitable for use in the 6.0 diesel.

Anyone care to lead off the discussion

It's not simply extended life coolant that you get at the parts store. IIRC Texaco is actually the original formulator of the EC-1. It's also available in Shell, Fleetrite (or is it Fleetguard), Caterpillar, and from Napa. The 100% is a little difficult to find but you can't use the 50/50 or you'll end up with a 25/75 water to coolant ratio because of undrainable system contents. You can search for EC-1 and get LOTS of recent threads on the subject.

I used Shell. As long as it says it meets the standerd for cat EC-1 you will be ok.

It doesn't say it but this document made me think CAT was responsible for the ELC-1 standard.

I switched to shell EC-1 coolant just because I didnt want to deal with the dealership hours and prices...I get it pre-mixed for 11 bucks a gallon.

is the cat in Cat EC-1 refering to category or Caterpillar.

I am still confused I see Zerex and Shell Rotella recommended as suitable. Where is the Cat EC1 ELC that I should be using available. Can you get it at Autozone, O reileys, Pep boys etc.

The cat stands for caterpillar EC-1

As far as where you can get it. You will not be able to find it at any autoparts store. You will need to go to a Cat, internation, volvo (big rig dealer), or other 18 wheeler dealer. I get mine from a local big rig lube place. Some truck stops will carry it as well. I did find it Cat, but they didn't carry the concentrate, the only thing they had was the 50/50. I didn't want to wait for them to order it. So I went to all the Big Rig shops till I found what I wanted

Labeling is confusing (maybe on purpose) but it should say "silicate free" on the bottle. I didn't find any at AutoZone or Advance Auto. Didn't check at O'Rileys. Carequest and Napa are supposed to have it. I went to my local Catepillar dealer and got it but they usually have to order. Most of the equipment they service with 50/50 premixed.

I am still yet to see the geling you guys speak of....I am not trying to be a d*ck but I just have never seen this geling on 7 engines I have had contact with....including my own. Three cooant flushes later and a filter setup and not a problem from the GOLD so many on here swore by for lots of years that I have been on this board....now the sky is no longer blue???Please explain what exactly and under what conditions is this happening?


Thanks
Joe

I don't really think that gold is bad, but I like the ELC because there is no silicant. I have read a lot on this subject over the years, and like you Joe I have never really had a problem with the gelling either. I figure it won't hurt anything running it, and there is speculation (not any real proff) that what everyone has thought to be casting sand all these years, is atually sillicant drop out. Makes since, and since no one has ever had the "sand" analized there is no way to tell if it is casting sand, or sillicant drop out. That's why I did the switch. I just figure that if international uses it on there 6.0's then it won't hurt ours. Granted there's are not the exact same thing, but I don't think the differences in there motor and ours matters as far as running ELC or not. That's just my stand point on it. I don't tell everyone to make the switch. I just did, and I tell people if they do make the switch make sure the coolant you get is CAT EC-1 certified.

I think the gold would be had for soneone with a bad oil cooler that's causing egr cooler puking issues.when the flash boiling takes place is when the silicate drops out and turns to goo,if I understand correctly.

Got it....I still think that no matter what anyone says, a coolant filter is a great idea. I was a fleet mechanic for nine years and I had Internationals VT365's to be exact.

A coolant filter was used on those as well.

I will continue to use gold coolant (I get it free from a friend) until somebody comes up with some cold hard facts and not just a "I heard it is bad so you better change it."

Take Care

I had the solids that I pulled out of my coolant filter analyzed. They were primarily (over 50%) silicon. I am certain it was casting sand because ALL of the silicon in the coolant would amount to ONLY about a half an ounce (according to the ASTM standards for the Gold coolant silicate content). My solids (and the amount of Si I calculated) were a LOT more than that.

Ford has stated that exhaust gas leaking into the coolant can possibly cause precipitation. It is my opinion that this is the goo that some people experience. Casting sand is in no way gooey!.
