Para003 Posted April 19, 2014 Share Posted April 19, 2014 Hi all or g'day from Oz. I have a B model with the C motor 673 turbo. Coming in to autumn( fall) and am looking for advice for which is the better type of coolant for antifreeze protection. We get down to a max of minus 12 C in winter! Thanking you in advance.

Freightrain Posted April 19, 2014 Share Posted April 19, 2014 I've always just run standard green car antifreeze mix in my truck. Used to sit out when I first got it(near 0* F) without issue.

farmer52 Posted April 19, 2014 Share Posted April 19, 2014 At the minimum you need a coolant approved for use in a Diesel engine. Although you have "dry sleeves", I would be hesitant about using a "standard" automotive (gasoline engine only) coolant. Just my 2 cents.A friend recommended Peak Final Charge Extended Life Coolant (red).50/50 mix of most coolants will protect to -34F (-36C).

Freightrain Posted April 19, 2014 Share Posted April 19, 2014 I've been curious, but since my 2000 Ford PSD had green in it(though you were to check PH levels), and the B came with green in it I've just let it be.

b61mack Posted April 20, 2014 Share Posted April 20, 2014 I have green in my B61 with a 300+, I went to an automotive store and bought mine. green worked for years before the red and never had any problems. if it was newer I would use red, that's what the coolant filter is for.

One can use a CF if desired. Other "colors" need a CAF.I determined why my E7 does not have a CAF because the fleet used RED coolant. 1 Quote Ken PRR Country and Charter member of the "Mack Pack" Link to comment https://www.bigmacktrucks.com/topic/35467-coolant-type-in-673-motor/#findComment-242732 Share on other sites More sharing options...
