what anti freeze

[CRM_66]

Well its a 1982 mci 9 6v92 dd,with dual radiators up high ,dont know when anti freeze was changed still looks good but decided to change it , does anybody have an idea to what brand anti freeze to use and i was told it needs to be a 50/50 mix help would be appreciated thank you shadow.....

Can't go wrong with 50/50 in most climates, but for the 92 series you need a solution with anti-cavitation properties I believe, due to the wet sleeves - others with more knowledge in this area will be chiming in shortly I'm sure!

Detroit Power Cool is hard to beat in the 92 series.most of the time the Detroit dealers sell it cheaper than a Walmart stocked anti freeze

Once you get the antifreeze, get yourself a bottle of test strips. You can use these to test the antifreeze for level of freeze protection, and you can use these to monitor the level of the various components of the solution.

What is the correct antifreeze for an 8v71?
Thx

Don't waste your money buying the pre mix it's good to carry to top off with but you pay a lot for water buying it

[Busted Knuckle]

Also be sure you get all the air bled out when changing it!
It is very expensive if you leave air pockets!

I've heard the bus grease monkey say that you can run any antifreeze in a '71 series, but you need anti-cavitation for wet sleeves, such as the '92 series.

I've been using the red antifreeze, it's said to have more heat carrying ability,  lvmci...

Gotta be careful going by just color nowadays - many companies are using whatever color they like and it doesn't necessarily mean anything anymore.

You can add Nalcool or similar to, at least the green. It is a water wetter, aiding in heat transfer and anti-cavitation.

LOL he is wrong there,surely he didn't say that,read the current DD spec,that is sorta like saying the old DD spec that approved 15/40 is still ok to use and you could use any water but ditch water times have changed .I use the green for people that want it but the heavy duty green in color cost more than the Power Cool extended life

The Monkey is not a good reference for Detroit Diesel knowledge.

I use Zerex Heavy Duty Extended Life Antifreeze in my Detroit Series 60.  I got my last batch for $18 on sale at NAPA.  ZXED1 is the part number at NAPA.  It has the right additives for a diesel in it.

I don't know if this is the right stuff for a 71 or 92.
