Our 6.7 motors take 9 gallons antifreeze 50/50. How much of it is used in primary and secondary?

 

My manual says 41.8 quarts (10.45 gallons). Per manual, be sure to use distilled water.

Does drain **** bottom left hold both amounts?

 

No, that is primary only. On the right side, there is another drain **** for the secondary.

 

So did I read that right 27 quarts in the primary and 12 in the secondary? My radiator is leaking and I am just going to replace it but I want to have enough coolant on hand once i do it and its 1899 a gallon so I want to have enough here? Could someone clairify that for me please?

 

The owners manual will have the correct amount.


I have not looked it up but that is where I would go to for common replacement fluids and capacity.

 

yea I thought so too it says 29Q bt its not broken down between primary and secondary

 

Oh, I see. I think you will have to break open the secondary at any rate to change the radiator out.


I think they only thing you can away without touching is the A/C condenser and the other 1/2 dz radiators.


Do some searching on youtube. You maybe able to find a video of the procedure and I'll bet that will give you some hints.
