I guess I could do that. Lol. Looking into those coolers yesterday, I don't think it's very much. But, it sure seemed a lot when you're laying under the truck and pop the hoses free to get them out.

 

Definitely. I took them of as well. That alone is 30% of the work. Just getting those bolts out of the lower bracket and back in to the exhaust manifold was a task and a half.

I'm curious what the weight reduction is. I'm guessing it's 60-70 lbs or so. Maybe more with the reduced coolant.

 

Coolant flushed and replaced with Rotella ELC. TSC has it on sale at 12.99 a gallon for the concentrate.

Initial impressions are good. My ECT and EOT are back within 4 points with everyday driving. At idle, they're within 3.

 

How were your thermostats? Did you replace them or reuse?

 

They were pristine. I just re-used them. With the EGR & coolers gone, the housing is super easy to get to. If I end up having problems, it'll probably take me thirty minutes to get them swapped out.

 

Wondering if you guys still aprove on the shell Rotella Elc. I'm about to do the flush on my 08 F250 it has 101k or what do you guys recommend?? Also wondering if this is the right bottle. I also wanted to clarify I'm gonna need 5 gallons of the concentrated right?

 

I flushed my system twice. Once when I first bought it and removed the egr, and just a little while ago, when I upgraded my camper to 30ft bunkhouse. The second time I used the nitrite free Rotella.

I watched several videos online, and flushed my engine with a garden hose into the degas, with engine running, and block drain plug out. This was recommended by my trusted D-Mech, and to me it just makes sense to do it this way.


I really like this guy, the way he speaks makes me think he is reserved and conservative, imo.

I ran and drained the coolant several times, plugging and filling up completely between cycles. I did this until the water coming out did not have a bitter taste - lol, i know this is probably weird, but all you do it put your hand under the stream of water coming out of your engine/radiator and barely touch the tip of your tongue on your finger. I was very surprised that it continued to taste very bitter for many flush cycles. Since I was changing from gold to red, I really wanted to make sure that I got every bit of the gold coolant out.

This is what I used...

 

I still recommend it. I've only put 15,000 miles on my truck in the past year and a half with a 2,000 mile trip in May. Much better deltas at 85 MPH. The key to switching is flush flush flush until you think you got it clean and flush two more times.

I did use a napa coolant flush additive about half way through which appeared to clean out a lot of garbage.

I also bought a vac lift on Amazon to make sure I got all the air out of the system.

 

So what do you guys recommend for coolant flush cleaner, the Vc9 or the restorer stuff. Just trying to do this the best way possible, and by chance do you remember the name of that cleaner you got at napa.?

 

I used the Zerex. White bottle. Maybe 32 oz or so.

 

I used the restore stuff from the Cummins dealer, can't remember off the top of my head exactly which one....flushed and filled 4-5 times with distilled and did the final fill with CAT ELC concentrate then topped off with the CAT ELC 50/50. I had about 40k on the truck when I did it and have had a coolant filter on the truck since new basically...
