ELC coolant changeover questions

Hello,

Been doing some reading on the ELC coolant change some of you have done. I currently do not have any coolant issues or oil cooler problems. Is it truly necessary to use the chemicals to clean out the block or is a complete and thorough flush (t/stat out, block drain out, tap water for a while then a thorough follow up with distilled flush) sufficient? Has anyone done it this way with success?

Ive been running a coolant filter for years and was thinking about the ELC upgrade.

Thanks for the time

If you oil cooler isn't clogged and you don't want it clogged I wouldn't do the chemicals, just make sure you have all the gold rinced out and refill with elc.

Thank you for the advice. I plan to tear out the turbo to rebuild it and figured id throw in a new oil cooler since I was right there anyway. The original is still in there and it has 72k on it. My deltas never spread above 15* unless Im towing my heavy 5th wheel up grades with sustained EGT temps around 1100-1200.
I kick myself for not checking the hpop screen years ago when I did the egr delete. I recall an upgraded SS screen they sell now, probably do one of those too. Then ill swap over to the ELC....what do you think?

Thanks

Well if your going to replace the oil cooler and you want to do a flush, do it BEFORE the new cooler goes in. And the oil cooler comes with the updated screen.

Yeah still not sold on the flush just yet. Ill do a little more research on it. Good to hear the updated screen comes with the oil cooler package.

Does the updated oem cooler also come with all necessary gaskets needed?



Thanks for the help

After doing some reading, by removing the thermostat it eliminates the long wait time for the engine to come up to operating temps between flushes. Is there a reason why I shouldn't remove it?

I plan to flush the entire system as recommended (no chemicals so i'd remove the t/stat to eliminate long wait periods between flushes)
Tear apart the top end to replace the oil cooler
Rebuild the turbo (seal leaking)
Make the swap to ELC

pretty much in that order.

It will take it longer to warm up without the thermostat.

Understood but if no chemicals are used (which require operating temps to work) and just a thorough flush is performed, then removing the t/stat makes sense to eliminate the LONG flush intervals waiting for the t/stat to open for water to continue it's flow.....right?

Yea, if your just using water, only problem is the thermostat is made into the neck on these things I think, I can't remember if mine would come out or not.

If not doing chemicals I would just pull the block drains, put a garden hose in the degas bottle and let it run thru with te engine and heater on. Just make sure your hose is out flowing the drains!
