After a bit of a delay I'm back at it.
Been too busy to work on or even drive the bus.
I'm getting ready to change the coolant in the auction bus I bought 6months ago.
I've been reading up on coolants and it sounds like I need one that meets ATSM D-6210.
I found one, at the local napa or o'reiley store.
Its "Peak final global extra life". Its got all the right words,
The only thing that got my attention was that it was an organic acid technology.
It says I can mix it with the "green" stuff but only to a 25% contamination level.
I'm planning on replacing as much of the fluid as I can.
The manual say this engine, 7.3, has an initial fill capacity of 31.2 qts, thats 8 gallons.
If I get atleast 6 gals out I should be OK.
I guess if I get less than the 6 gal out; I could fill with water, circulate it with the engine to dilute it and then drain again. I'll have to do some high school math to see
how often I have to repeat to get it below 25%
Its been a while.
Does anyone know anything about it, is it any good and is my plan sound?
