Coolant Flushing World Record in the Making

[colonel angus]

Flushed the truck 14 times and it's still dark as Tea.

Procedure:
Fill with tap water, drive until hot ~195 open both fumoto valves and radiator pet**** collect about 6 gal. of hot cloudy Tea. Repeat

It does settle out a bit but is still Tea colored.

It's improving, but reallllly slow i need encouragement to continue.

Would it help to pull the thermostat or is that counter productive?

Ph is really low Acidict via test strips.

Is it remotely possible that it won't clear up?

Pulling the t/stat may cut it in half, i did my whole flush without the t/stat used cardboard in front of Rad to build heat so the Restore and Restore+ would work but still took 12.5 hrs and 48 gallons of distilled water but it's clean.

Are you using any restore or VC-9

[Ronisonce]

What I did, I stuck a hose in the resevoir.. Opened the fumoto valve and held the truck at like 2k rpms for about 15 minutes.. Before that, I couldn't for the life of me get it clean.

[colonel angus]

I did VC-9 before the new cooler and restore and restore + both 1/2 gal at a time after.

I've been flushing for 2 days with no end in sight.

I'll run it until the thermostat opens and then from then on flush with the fumoto's open and the flow adjusted to keep it around Min. level.

Our local lake is going to go dry.

Took me 5 flushes to get clear from the original Ford Gold and 12 to get clear from running around with 1 Gallon of Restore. I did not use VC-9 or Restore+.

I would pull your T-Stat...I did mine 4 times yesterday. Pulled it out when I started, put it back in for the one hour drive, back out and then back in when done. The T-Stat only starts to open at 192...you are not getting full flow through it.

Here is what it looked like after the first 5 flushes to get the Gold out.


Here is what it looked like after I ran it with Restore.


I did not get a picture when done as it was dark, but after 12 flushes it looked as clear as the first pic.

With the thermostat in will i be leaving the radiator and it's fluid out of the flush?

I've back flushed it several times and it's clear.


Plan is to flush this am keeping it hot and remove tstat in the pm once it clears up for full cleaning.

I had my Tstat out the whole time I was flushing. That way, you're always running fluid through the whole system instead of having to heat it up each time. Definitely needed the cardboard to get it up to temp for the chemicals though...

Pull the thermostat and also be sure to have the heat set at high in the cab. Otherwise you wont clean the gunk out of the heater core and lines.

Did you have a coolant filter installed prior to the flushing? I did and it only took me three rounds to get the coolant to run clear.

Also, how's your oil cooler performance? Is it possible that your oil cooler is plugged which is limiting the amount of your cooling system affected by the flushes?

Part of your problem is also in your actions. Instead of just opening the pet****, you need to pull the lower rad hose off. If you don't you aren't getting nearly as much fluid out as your should for each flush. Plus, you are wasting a TON of time by using the pet**** since it is so much slower.
