We’re in the field almost every day.
We’ve been expecting to see poly organic, nitrite-free antifreeze as a factory fill for quite some time.
We finally saw it. Two 2011 Freightliners had bright red coolant that tested negative for nitrites.
If you’re wondering what’s in your new equipment, dip a test strip. If the bottom pad doesn’t turn pink, chances are you have a poly organic and are protected against nitrite-damage to aluminum radiators and heater cores.
Remember: it’s a best practice not to add nitrite to these newer, technologically advanced coolants.
