I bought an updated oil cooler for my 05 6.0 as the temp is running around 210. But I was reading alot about flushing it before installing the new one. The EGR is deleted but I was curious how to go about flushing the cooler first?
Some of the updated coolers, like the sinister can have 20° or 25° delta out of the box. So, if it is not an OEM motorcraft cooler, than the only thing you can do to fix the delta is to put an OEM cooler in. IMO for the oil cooler it is either an OEM cooler, or a BPD air cooled oil cooler.
If you have an OEM cooler, I have flush procedures in my signature block. I did not create these, but I have used them You really need to follow the directions, to include draining the block each time, I recommend the Fumoto valves to make it easier.
One more thing to my above post. If you do switch to ELC coolant, it's a great idea to put a label on your degas bottle so someone doesn't mix coolant later down the road. If you follow my post you'll have a gallon of 50/50 left over. You only need 3 1/2 gal of concentrate to refill. So top off the remaining 1/2 gal with distilled.
You don't need to back flush before installing the new one, though if you do it may buy you some time before needing to install the new one. I had a new one on the shelf for a year or more after a back flush bought me more time.
What you want to do before swapping is a thorough system flush, make sure you open both block plugs, a lot of guys install a Fumoto F108N behind the starter so you only have to drop the starter once. I put Fumoto's on both sides with some 3/8 tubing so I can drain the block into a bucket without making as big a mess. Your gonna need about 20 -30 gallons of distilled water and 4 gallons of Cat EC-1 ELC concentrate. DON"T buy 50/50 and now is the time to get rid of the gold.
For back flush you can buy a fitting that allows a garden hose hook up or get an IPR coolant manifold and filter. Or better yet their Gen 3 EGR delete to clean up your delete and be able to filter or back flush. That'll let you hook up a hose and blow everything backwards thru the oil cooler. Also don't use chemicals live VC9 or Restore, liquid Cascade dishwasher detergent works great.
For the IPR, google IPR Research, not a sponsor so I can't post the link.
Also get a bag of microfiber rags to clean the oil reservoir under the oil cooler, DON'T USE BLUE SHOP TOWELS they leave too much lint. Cleanliness is very important during the whole job. You'll have the intake manifold off and the oil reservoir open. Also a good time to split the turbo and clean the veins and unison ring since it's off anyway.
DTR has a good video on the oil cooler swap with a BPD EGR replacement. Just ignore the EGR part. And be super careful with the wiring harnesses, there's a guy on here now that just did heads and he's having harness problems at the FICM
Once you flush the system real good with the garden hose, do 3 or 4 fill N drains with the distilled before you do the tear down. Everything will be nice and clean for the new cooler and coolant. Since you EGR is deleted you don't need an airlift to fill the engine back up but it sure makes it easy. When I did mine I put a new EGR cooler in so I had to use an airlift to make sure I had coolant in the EGR and oil cooler. You can get a cheap one on fleabay. https://www.ebay.com/itm/Radiator-C...199261&hash=item5204f5331d:g:ytIAAOSwkmZdVVSH
Alright that seems fairly straight forward. I really appreciate the help!!! Where do I get this other coolant. Iv heard about not using the gold stuff. But i have spoken to ford and other part stores and they all seem to be unaware and can't help me.
