I'm currently getting all my supplies to get my 60k mile maintenance out the way. One of which is a coolant flush and replacement. I contacted Valvoline regarding the correct coolant to use.
This is what I got:
But I also read this:
So WTF am I going to use? I used Zerex G-05 in my '02 Ram 1500 3.7
This is what I got:
For the 2009 Dodge Ram 1500 with the 5.7 Liter Hemi, we recommend the use of the Zerex G-05. *This product is a Hybrid Organic Additive Technology (HOAT) coolant that was designed to be used in the*2002-2012*Chrysler applications. *This product will be yellow in color unlike the factory coolant we produce for Chrysler that it Orange however, it will mix with the existing coolant in the system without any issues.*
But I also read this:
5.7L Engine 1500 Models
MOPAR® Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) or equivalent.
16 Quarts (15 Liters)
CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Technology (HOAT) engine coolant (antifreeze) or any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, it should be flushed with OAT coolant and replaced with the specified OAT engine coolant (antifreeze) as soon as possible.
Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator engine coolant and may plug the radiator.
This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze) is not recommended.
