This past weekend I finally got to flush out all the old green conventional coolant and charge my cooling system with CAT p/n(238-8647) ELC coolant on my truck. Also while I was at it I also replaced my water pump, water pump outlet, thermostat, radiator hoses, and coolant filter. For parts I went all oem the thermostat, upper, lower and degas bottle hose I got from my local Ford dealer. Coolant filter I got from M&D distributors it is a Baldwin filter that I purchased too. Water pump and water pump outlet it got from Riffraff diesel and is a Navistar part. Next I got 5 gallons of CAT ELC coolant from my local Rush Truck Center. Then finally I got 20 gallons of distilled water from my local Walmart. I followed Gooch's coolant procedure from a thread I had read a while back. From start to finish it was a pretty straight forward and easy procedure. What made the entire coolant flush easier was the peak flush n' fill kit that I got from my local Autozone to back flush the heater core. Overall after it was all said and done my truck runs a lot better, cooling system works tons better and so does the heater lol. From all my research and asking around ELC coolant was the way to go especially for this hot summer. So for anyone that are wanting to change their truck's coolant to ELC hopefully this will help.

 

Thats a great thing for your truck ! Congrats on the chore which i know it is. I did mine in the winter when doing my oil cooler and it was not too fun. Pretty cold and my hands were froze.
And i see you got the correct part number for the cat coolant also.

 

Thanks I really appreciate the reply! It was a chore, it took me all morning to do the flush along with a majority of an afternoon doing all the other stuff. But it was well worth it. The CAT coolant was actually the coolant I didn't order. I had ordered p/n 119-5150 CAT coolant but 238-8647 was all they had on hand so I took that instead lol. Other than its was very well worth it.

 

As long as your truck is a late 99 to 2003, ELC is fine. If it's an early 99, it's bad for the injector cups and doesn't play well. Nice work! It feels good to maintain these things.

 

That's one thing I made sure is my truck was compatible with elc. My truck is a 2000 year model and my engine serial was way above 940614. From looking at that I knew I was good. Plus, it's good having a piece of mind that I won't have to worry about my cooling system for a very long time.

 

Byron beat me to it, but I too was going to ask what year your rig was!

Just for info and future searches, here's the Gooch thread you referred to in your first post: Gooch's Coolant Flush Procedure and In-Depth Coolant Information - FTE

Not to throw a monkey wrench into things, but did you get the CAT EC-1 rated ELC or does it just EC-1 on the label? They are two different animals - ask me how I know! (The jugs are almost identical except for the fine print). Nothing wrong with the plain EC-1 but it still requires the test strips and related additives.
Just on a side note. With the ELC EC-1 rated coolant you will not need the coolant filter. The so-called "sand" commonly referred to is actually a precipitate from the conventional coolant. Hence the main reason for the EC-1 rated coolant.

 

The coolant I got is a CAT EC-1 rated elc coolant straight from CAT.
