Coolant Flush

[jp45601]

I just bought my 6.0 in september & I dont know if the coolant is the Ford Gold or what? It is gold sorta in color. I want to flush the old cooloant out come Spring. I am a little leery about using restore & restore + since I have read about how it could end up clogging my oil cooler. My oil & coolant temperatures are only 7 degrees apart. my eot is 197 & my ect is 190. That was while I was running 70 mph. Being this close do you think that I shouuld flush it with restore & restore+ Or just flush out the old coolant then install the ELC coolant? I appreciate any help that anybody can give me. Thanks in advance.

flush with restore, skip the restore +. I feel that restore + pushed my deltas up. But my cooler was already getting bad. So thats why I ran it.

I just flushed mine out with distilled water a few times yesterday, filled up with shell elc and called it good. Like you my oil cooler is still good, I'm not running the risk of clogging it by running cleaners. Others have done it this way and were just fine.

also previous owner, put 3 egr coolers in and 1 oil cooler in prior to 2008. So I think that tells me the care taken on the cooling system (lack of).

Im with you on this one. Ive yet to flush mine due to time but when I do Im going this route. I even bought the VC-9 but backed out. I am also sticking with the gold due to warranty. I just cant see plugging up the oil cooler. I mean its going to happen if you flush it with the chemical. Ford recommends flushing with the chemical IF the levels of your current coolant is shot. Mine is not and has never been so I see no reason to pour a bunch of de-scaler in it.

Thing to be aware of is that you can not just drain out the Ford gold junk, flush only with distilled water and think everything will be cool. You are changing the coolant type, not just the coolant. To change coolant type requires that you flush and use chemicals. The Restore removes the silicate build up on the walls of the cooling system that helped in cavitation and then turns it in a goo, slim and it will this is not the problem it's the Restore+ that removes the mineral build up. I had 4-6* deltas before both flushes and the same after but i had about 29k on mine higher the miles the bigger the chance of oil cooler plugging with mineral build up useing the Restore+.

I would like to Thank everybody that answered my post. It was all very good information. I decided that when I flush my coolant that I will use restore. I wont use restore + till my oil cooler starts going bad. Then I will use restore & restore + . When I do the flush in the spring, I will make sure that I do a thorough job of reverse flushing. I feel that the best defense against the oil cooler from clogging up will be reverse flushing.

can a flush w/restore be done with the motor out of the truck ?

IIRC you need 185* temp for it to properly clean.

I'm in the process of flushing now and had a hard time gettting the truck to operating temps with the thermo removed and the front grill blocked up. Just an FYI if its around 45* outside it will be a little tougher, after being on the highway for 20 minutes it finally warmed up, but driving on back roads won't do it.

I also couldn't get my block drain plug out so I'm going to flush an extra 3-4 times. The 8mm hex key is stripped a little. I tried some PB but i don't think that will do much with the oring right there. When I bring the truck back from the restore+ flush I'll try to loosen it when block is at 190* Thoughts on flushing a few extra times?
