ok i got the new rad ($334 us free shipping no duty at the border) i went to tractor supply for 3 jugs of antifreeze($50) 4 jugs distilled water ($4) the new antifreeze is red the old is green.my question is do i have to flush all the green antifreeze out before i add the red antifreeze(might need 1 more jug of red) what is the proper way to flush the system
Don't make this harder than it is.
Drain what you can, and refill.
I recall 32 quarts, that 8 gallons total, 4 AntiFreeze, 4 water. mix 50/50 as you go
I would purchased pre treated (w/SCA's) anti-freeze
Drive it until it drops

as a matter of fact! It had John Deere (green) antifreeze in it from the P/O. I bought "FLEET CHARGE" from TSC and distilled water from wallyworld. mixed it in a couple of 5 gal jugs. Drained the radiator and then refilled with the RED stuff. made an ugly color but it's working good..Took the wife to the doctor in 98 degree weather with the A/C on max and the engine was 198-203 through town.
Fleet charge is pre charged with SCA's

Above the starter is a block drain, after draining the radiator, remove this plug to drain the engine.

"drive it until it drops" i work hard for every penny i make(as most of us do) and take care of everything i own.i have a habit of doing things right or i just dont do it!!!

I forgot that part of the change...was dealing with other projects at the same time. and now I have a Vacum pump with nasty sounding bearings...Oh well just MORE to do before we leave on Tues. I did undo the hose that comes from the bottom of the rad to the heater line. The drain thingy ( can't say it here) is broken off on the bottom of the rad.

Thanks Trampsdieseltruck! Already drained, refilled and running FINE.
Did you test the DCA-4 coolant level and adjust it?
Without it being at the proper level, you WILL have cylinder corrosion issue some time in the future.
First cylinder #8 will get pinholes letting coolant into the motor oil, not long after you sleeve #8, cylinder #7 will go out and you will be broke chasing pinholes!
I believe sleeving 2 cylinder back then cost about as much as a new block.

Verified 19 mpg city taking off slow as hell the shutting down at red lights, and with the radiator grill blocked flush, no bed cover, "drag shoot" mirrors on I get 24 mpg at 50 to 55 mph on the freeway empty!
However, with a bed cover, no mirrors and Hydroxy
Put in 4 gallons of the Zerex G-05 and 2 gallons of water. Since it holds 8 gallons total, I assume the remaining water was in the engine. If not, I have a huge air buble and will be back here soon crying.
BTW: Used distilled water to flush and refill.

If you didn't drain the block you are probably good, if you did drain the block you haven't bled the system properly.
