A little worried about doing a coolant flush
Ok, so I have been reading alot about doing a coolant flush on my 06 with 75,000 miles on it. Not sure if it has even had it done before as I purchased it with around 50,000 miles on it.
The only reason I would like to do this is because over the summer towing my 12,000 lbs horse trailer it seemed like the fan engaged a little more often then last summer, plus like i said I dont know if it has had a flush ever.
But after reading alot I'm worried about doing more harm then good, and possibly clogging the oil cooler while doing the flush? Any thoughts on this, and no I have not got any gauges yet to moniter temps better so I have no base line numbers to go by. Thanks....

If you decide to flush this may help.

I will look into the scangauge, I then can get a good set of numbers to go by first, and while I'm doing the flush.
No I dont have a filter on it.

I'm in the middle of a flush right now, same miles as you 75k. So far so good and my EOT temps have dropped after doing some back flushing. Still have to do VC-9 and final distilled flushes.
At the very least you should dump your coolant and do a distilled water flush and replace coolant, but imo doing a very thorough Restore and VC-9 flsuh will be worth it.
Couple things I'm really glad I did. #1 was to install Fumoto drain plugs #F-108N in the block drains. I pulled the starter to do the passengers side. Way worth it makes draining a snap and can do it right away without having to wait for it to cool. I also am pulling the lower rad hose by loosening the clamp and then knocking it off with a 2 x 4 so I don't get splashed. I'm using very hot water to fill so the truck is damn near up to temp after I start it. I didn't pull the thermostat.
Also I back flushed first thing before the Restore flush(I was waiting for my Fumoto valves to come in). Shot hot water through the heater core, radiator and most importantly the oil cooler. I used a turkey baster to shoot some restore directly in the oil cooler and let it sit for a couple hours. did that twice, backflushed the crap out of it and then filled with water and did a little run down the highway. Just doing that dropped my delta from 28* to 9*.
I'm still going to replace my oil cooler and do an egr delete but I'm almost at the point where I wouldn't need to. My thought though is that if I'm going to plug a cooler back up after the flush I'd rather it be the old one.
Cheers and good luck.

I'm for sure going to do a flush soon. But first my list of things in order.
1. Get something to read my temp numbers so I have a baseline to go by. What do you think of the scangauge? Or any other affordable devices.
2. Need to get me some Fumoto drain plugs ordered for sure, have been burnt by coolant before (no fun)
3. Get all the stuff to do the flush with water/ VC-9/ Coolant etc.

Edge Insight for monitoring
Fumoto block drain valves
Restore for 2 hours @ 65 MPH with cardboard covering the grill (if under 60degrees F ambient)
Restore Plus for 2 hours @ 65 MPH with cardboard covering the grill (if under 60degrees F ambient)
Backfush the oil cooler from your filtered hot water tank
Backflush the heater core from your filtered hot water tank
Backflush the radiator from your filtered hot water tank
24 Gallons of distilled water
ELC coolant
Took me 2 full days but goy my 30 degree spread down to 9 now, The love you put into it is the love your gonna get out of it. Good Luck!
