Hello again, guys. I'm about to change the coolant in my 2007. 5 RAM 3500/6. 7L. The instructions call for HOAT coolant. There is some difference in opinion at the auto parts store where I purchased a couple of gallons of Zerex GO5 antifreeze. The bottle is unclear as to whether this is HOAT-type antifreeze. It DOES state that it is good for Cummins engines, supposedly up to present. It appears to me that this is the right stuff but one guy says no, the other yes (confusing??
).
Can anyone here give me a definitive answer? Is Zerex GO5 the right stuff? I hate to damage my engine. Thanks in advance... .
