Switching to ELC after Coolant Leak
I have a 2009 F250.
Recently I noticed after a long trip towing that my degas bottle was low and I have needed to add coolant a few times since. I finally had a chance to track it down today and found that the upper radiator hose was leaking (old style). I ordered a new upper and lower hose today. I also went to the international dealership and picked up Fleetrite ELC and tracked down a Cummins dealer that had restore plus, but no restore.
I know that i have to run chemical cleaners to switch coolant types but I am weary about doing the full flush with both restore and restore plus. I am considering using Restore Plus only. Until recently, I rarely had a difference between EOT and ECT. If I did it was only by a couple degrees if i was towing. Now (the last week) I am starting to see 2-5* difference @ 70 mph. I don't want to ruin an oil cooler that is mostly working okay, but I think I really need to get this Gold coolant out. I have been running a coolant filter for about 10,000 miles and have changed it once. Hardly anything came out of the first one.
I'm hoping for some input on what you all would do here. Hopefully all my parts (including egr delete) will be in by the middle of the week. For now my truck is sitting with a belly full of distilled water.
