As I read through the various forums and posts, it almost seems that half of the posts now are regarding coolant, flushing and ELC. Now I'll admit I have my fair share of oil cooler posting but I have to wonder, is ELC actually preventing issues? I am starting to see oil cooler postings where the owner had switched to ELC already, and to be fair they may have already had a clogged cooler, but the question still stands, how is ELC doing, has it prevented oil cooler issues (EGR cooler issues) and just as importantly has it actually improved your ECT / EOT delta's?
For the record, I finally switched to Zerex ELC over the weekend and glad I did.
Mine plugged after a flush. It was full of sand and GOO. I have had a coolant filter since 1,000 miles, it has 57,000 now. Picking it up from the dealer tomorrow morning for a cooler and EGR cooler replacement.
How long had you been running the ELC previous to your failure?
Was the previous oil cooler so clogged that, maybe you didn't get an effective flush and got rid of the garbage that was present in the system, or was there junk left and that was what immediately clogged your new cooler?
I would like to hear about anyone that has been running the ELC for a long period of time and had an oil cooler failure, BUT after the fact of running the ELC for an extended period of time - say 1 year later or more.
if your cooling system was neglected and you flush with restore restore plus, its a gamble. just be prepared to watch your delta and plan for a new oil cooler.
Absolutely right. We proper maintenance you shouldn't have a problem. The problem is Ford said the stuff was good for 5 years or 100k so people ignored it. I think that if your truck has over all these 6.0 are aging past the point where they should have been flushed and cleaned though most have not been. The point of the flush and cleaning is to prepare the cooling system for a clean coolant charge. The only real way to know what you are starting with as far as the oil cooler goes is to replace it and start with a clean fresh system. If you cooling system is in good shape it should survive a cleaning. If it is marginal it may not.
If i switch to Zerex ELC do I have to add the Motorcraft additive to the coolant or change and go..... I need to do this on a 6.0 i have done this on cars but not on my truck is it the same just get a flush kit from AutoZone.....
This is a little different than the car flush get some of this that the big boys use
Here is the Restore Product from Cummins dealer http://www.fleetguard.com/pdfs/produ...LI33024-GB.pdf
do a search on coolant flush and a free weekend i used 48 gallons of distilled water and NO Motorcraft additive to the coolant:doh:
