Coolant Flush

[dbullard]

It is time to do the coolant flush on my '06, while I am in there I am going to replace the hoses and thermostat and I am wondering if any one has any good recommendations for a coolant as well as flushing the block??

I think it's the Turbo Diesel Buyer's Guide that discusses fluids for the vehicle (anyone know for sure?).

Pages 246-248 address fluids, it'll be there.

Flushing the Block

Ok, thanks for the fluid advice, what about anything for the flushing the block??

Im getting ready to do mine aswell and from what ive read it sounds like the water pumps seem to go around 120k-ish so might be a good time to do that if your in there, im going to do mine.

I use Finish dish washing powder. About 1/2 cup.

I reverse flush through the heater core after about an hour of running the flush.

Remove the bottom rad hose and run until the PPM equals the tap water.

I also alternate hooking up and unhooking the lower hose with the rad cap off and usually get some stuff out of there too.

Whatever you do, be sure you flush it out enough. You dont want the Finish staying in there.

Mine is a 12V. I dont know if the procedure wouldbe different for youre, but this will give you an idea on what youre doing.



JM. 02 YMMV dont take any wooden nickels etc. etc.

I dont have any flushing advise, other then just use water, and pay attention to the coolant requirements based on your manual. Two bit's of advise i do have, based on changeing my 05's coolant a week ago. First, if the 06' radiator petcock is the same as my 05', be careful. I turned the petcock on mine one full turn, and it was slow to drain. Got back under there and turned another full turn and it got much quicker, but the backup nut inside the rad came off. . After fixing that pain in the ***** i started the flushing procedure. Long story short, be cautious of air pockets in the coolant system. This truck was the worst of anything i have ever owned about getting air out of the system. . I mean anything!
